IBM Tivoli Storage Resource Manager: A Practical Introduction
Preface
Storage growth continues to accelerate, and the cost of disk can approach 80% of total
system hardware costs. Yet, the storage in most businesses is typically only about 50% used.
How can you take control of your storage assets to render utilization more efficient and make
the most of your storage dollars?
IBM® Tivoli® Storage Resource Manager helps you discover, monitor, and create enterprise
policies for your filesystems and databases. You will find out where all your storage is going,
and be able to act intelligently on this information. Application availability is improved because
you will have early warnings when filesystems are running out of space. If you are thinking
about server consolidation, you can use IBM Tivoli Storage Resource Manager to help
efficiently utilize your accumulated storage resources.
This IBM Redbook shows how to install, configure, and protect the IBM Tivoli Storage
Resource Manager environment; how to create policies; how to define automated actions like
scripts or SNMP events when policies are violated; and how to produce detailed, meaningful
storage reports. This book is intended for those who want to learn more about IBM Tivoli
Storage Resource Manager and those who are about to implement it.
The second edition of this redbook is updated for IBM Tivoli Storage Resource Manager
Version 1.2 and includes information on IBM TotalStorage® Enterprise Storage System
reporting using CIM/OM, filesystem extension, as well as on how to integrate IBM Tivoli
Storage Resource Manager with other Tivoli products.

Introduction to Storage Resource
Management
Industry needs Storage Resource Management (SRM) today in open environments for the
same reasons that industry needed Storage Resource Management in the mainframe
environment in the early and mid 1980s. Businesses are generating data so fast that data
storage and data management capabilities are being overwhelmed. If these capabilities
cannot handle the growth, then at some point, the next transaction cannot be captured, and
the business will stop.
Two key problems which impact this situation are:
򐂰 Storage costs are too high
򐂰 Storage management costs are too high
SRM tools will help companies lower their cost of storage, and of storage management.
In this chapter, we:
򐂰 Identify the business and technology considerations, which caused the development of
SRM tools in the UNIX and Windows space
򐂰 Discuss SRM:
– Benefits of using SRM tools
– Functions that SRM tools should accomplish
Subsequent chapters introduce a solution for SRM - IBM Tivoli Storage Resource Manager,
and discuss deployment architectures, installation and design considerations, operations, and
maintenance.

1.1 What is Storage Resource Management?
Tivoli uses the following definition for Storage Resource Management:
“Storage Resource Management (SRM) is an active, intelligent, business-centric
management solution for storage resources across the enterprise. SRM enables
administrators to visualize their distributed storage network, establish management
policies, and report on resource utilization. Enterprise SRM must support heterogeneous
storage environments, integrate with current and future technologies, and enable policy
based automation to simplify administration. SRM is intended to reduce system costs,
improve return on investment, and reduce the risk of application downtime.”
Figure 1-1 provides some additional definitions as used by outside sources.
SRM Definitions
SRM is a collection of automated tools that enable
administrators to visualize a distributed collection of storage
resources, to make intelligent, informed decisions about the
usage of those resources"
Enterprise Storage, Storage Resource Management Update, Sep 2001
"SRM is a component of overall systems management
infrastructure that improves application availability...by
providing capacity and performance trending, storage and
SAN device configuration, and removable media
management...SRM can help synthesize a unified view of
dispersed and heterogeneous storage deployments.
Gartner Group, Storage Resource Management for Distributed Systems,
ibm.com/redbooks
Figure 1-1 Storage Resource Management definitions
1.1.1 Storage Resource Management, then and now
Storage Resource Management has existed in the mainframe world since the mid-80s,
however, the requirements have only comparatively recently been recognized in the open
(Windows and UNIX) environment. The open environment is also dramatically different from
the traditional mainframe environments of the 80s. In the first release (in 1985) of storage
management software on the mainframe, a company did not go out of business (at least in
the short-term) if their systems failed. Companies had paper systems to fall back on if
computers failed.
Today computers are typically the only vehicle for storing a company's business data.
Computers and storage are now mission-critical.

IBM Tivoli Storage Resource Manager: A Practical Introduction
Today, you need to manage storage to stay in business. You cannot manage what you cannot
measure, and Storage Resource Management is a key tool for measuring and managing
storage resources.
Open environments today are larger and the systems are much more heterogeneous than in
the last century. Table 1-1 summarizes some of the other major differences.

1.2 Storage management issues today
Storage Management Issues Today
Growth (both business transactions and storage
infrastructure) is overwhelming people, tools, and
processes
Unmanaged storage costs too much
Manual Storage Management costs too much
ibm.com/redbooks
Figure 1-2 Storage management issues today
Figure 1-2 summarizes current storage management issues:
򐂰 Data growth
򐂰 High cost of unmanaged storage
򐂰 High cost of manually managing storage
1.2.1 Growth
The single biggest issue is growth. Growth is being driven by three general trends:
򐂰 Business transaction volumes are growing
򐂰 Businesses are now storing more information, from different formats and sources, than
ever before. These include audio, graphical, and other scanned data that previously was
stored only on film, paper, or other traditional media.
򐂰 These new data types (like music, video clips, images, graphical files, etc.) require more
storage per file than older data types like flat files.
The data and storage infrastructure that support this growth is itself growing dramatically.
Storage growth rate is estimated to range from 50-125% annually, depending on the industry
or consultant report of your choice.
Rapid infrastructure growth creates a number of technology and management issues, shown
in Figure 1-3.

ibm.com/redbooks
Figure 1-3 Infrastructure growth issues
Server growth
Major companies have hundreds of large UNIX servers, and sometimes thousands of
Microsoft Windows servers. They are deploying more servers every quarter, and most large
companies have a large variety of different hardware and software platforms (often not by
design) rather than standardizing on particular configurations.
Staffing growth
While we know that storage and data are growing rapidly, support staff numbers are not. This
only exacerbates the problem. An average corporate server may be supporting in the order of
3 TB of data in the coming years, yet it is estimated that a typical systems administrator can
manage only 1 TB. Since in today’s economic times, businesses are looking to cut costs,
most are shrinking rather than increasing their IT departments. Clearly, more intelligent and
powerful applications will be required to support this environment.
Storage data growth
Although companies are growing their data storage at around 50-125% per year on average,
larger companies may see even higher rates. A typical large company may have as much as
150 TB of data to store installed within the next two years. Total storage reserves of 150 TB to
handle the growth in storage with storage is being consolidated into SANs (Storage Area
Networks). However, SANs do not solve the underlying problems of mismanaged data and its
explosive growth. SANs concentrate the storage, the data, and the problems, and emphasize
the need for management.
Chapter 1. Introduction to Storage Resource Management

1.2.2 Storage costs too much, and money is not used efficiently
Two of the principal issues driving storage management requirements are the costs and
inefficient utilization of storage.
Costs
Storage is a large portion of IT budgets. Even with disk prices dropping at 30% per year (on
average), if storage requirements grow at 100% per year, total costs spent on storage will
grow 40% year-over-year. Storage has to be managed.
The fact that storage is inefficiently used is doubly critical in today’s environment of tight
budgets:
1. Storage administrators do not have the tools to answer questions like:
– How much storage will I need next year, given my current growth rates?
– How fast are my databases growing?
– What servers are running out of storage today?
– Can I compare the forecast on demand versus capacity from last year to the actual rate
of growth that occurred this year?
2. Because they do not have the answers to these and other questions, they wind up:
– Buying storage at the last minute (paying too much money for it)
– Buying too much (better to spend too much money on storage than to not have enough
when it is urgently needed)
Storage Resource Management tools would help the storage administrator answer these
questions, and allow corporations to buy the right amount of storage at the right time.
Utilization inefficiencies
Data protection schemes (RAID, mirroring, replication, etc.) are used to protect data from disk
failures and other hardware errors. Allocating and using additional disk for data protection is a
good business decision, and is not an inefficient use of storage.
However, there are many other ways that disk is used inefficiently. Here are a few examples,
and note that if the data is mirrored or RAIDed, then the problem is accordingly multiplied.
1. With direct-attached storage (whether internal or attached to a SAN) in some cases, a
very small percentage of available storage is actually used for application data.
2. Applications are installed, but then are not used. No one tries to locate these unused files.
Application upgrades can also leave unneeded files.
3. Many files are created once, used once, and never accessed or used again; for example,
for testing purposes. This is an example of a stale or obsolete file.
4. Some files are duplicated to other directories or systems, and later the need for the
duplicate file goes away. The duplicate file is no longer needed, but it is cheaper to leave
the duplicate file where it is rather than spend the time to try to find it.
5. It is increasingly common to find music files (often illegally copied) video clips, and other
personal data items placed onto expensive corporate storage.
Current open systems storage utilization rates can range from as low as 25% (direct-attached
Windows servers) to 50-60% (SAN-attached storage). What this means is that on average, if
a company has 100 GB of storage in a filesystem, there is about 25 to 50 GB of actual
important data on that 100 GB of storage. The rest of the disk space is being wasted.
8
IBM Tivoli Storage Resource Manager: A Practical Introduction
If storage is growing at 100%, and companies are using only 25% or 50% of what they buy to
hold real data, then companies are buying storage they do not need, because they cannot
manage data efficiently.
Table 1-2 Current estimated open-systems efficiency rates of storage utilization
Environment
Efficiency rate (typical)
NT Direct-attached
25%
UNIX Direct-attached
50%
FC SAN-attached
70%
Example 1-1 (for a low-end NT environment) and Example 1-2 (for a high-end UNIX
environment) show how the numbers can add up.
Example 1-1 Storage costs in NT environment
A utility company in the Northeast has 150 NT servers with internal disk, with an average
of 25GB usable per NT server. Given requirements for mirroring the OS disk, a hot spare,
RAID-5 for the data, and experience that buying a server fully populated with disks is less
expensive than adding disks to a partially populated server, the client bought 6 disks per
server to get 1 disk for actual data per server. The average cost of the NT servers was
$25,000, and the 36GB disks cost $640 each (market price), with the controller costing
$1100. The client was spending about $5000 per server (disks plus controller) for storage.
The client
spent 6 x 150 x $640= $576,000 for 32TBs of raw disk
to get 1 x 150 x $640 = $96,000 for 3.75TB of disk used for storing data, or
15.4 cents per MB usable.
Vendors argue that disk costs 1.8 cents per MB ($576,000/(32.4*1000) = 1.77 cents). While
true, it is misleading. Companies buy usable disk, not raw storage.
Two comments:
1. The difference is partly the cost of unmanaged storage (and partly the cost of
protection).
2. 15 cents per MB is close enough to the cost of enterprise disk to justify investigating
storage consolidation.
Example 1-2 Same examples, using enterprise storage
We re-calculated the same example using enterprise storage.
Typical efficiency (space used/space available) in enterprise FC SAN Storage is less than
50%. (It is more that the rate for internal storage because more attention is paid to
expensive fibre channel storage.) For the purposes of this example, we are assuming a 50%
‘best case’ scenario.
To get 3.75 TB of usable disk, the customer would have to buy 7.5TB of disk from a vendor.
Using 72GB mirrored disks which cost over $15,000 each, the customer would
buy 14 disks/TB * 3.75TBs * 2 (efficiency factor) * $15,000**/disk = $1,575,000,
to get 14 * 3.75 * $15,000 = $787,500 of usable (3.75TBs) of disk, or
42 cents per MB list price usable.
** -
90% of the current list price from one well-known storage vendor for a 72GB disk
Chapter 1. Introduction to Storage Resource Management
9
In the examples for 3.75 TB (Example 1-2) the amount of disk bought and not used for storing
original data (excluding data protection) was:
򐂰 $480,000 in the NT example above (75% of storage costs)
򐂰 $787,000 in the enterprise disk example (50% of storage costs)
If you extend the two examples above to 150 TB of data, then customers would spend either
$23,000,000 (for the NT example) or $63,000,000 (for the enterprise example) for storage.
Given efficiency rates on 150 TB of used disk:
򐂰 75% of the $23M, or $19M, would have been wasted in the NT example
򐂰 50% of the $63M, or $31.5M, would have been wasted in the enterprise disk example
These costs are the price for not managing storage well.
How much of this could be re-captured by using Storage Resource Management software?
Storage Resource Management can help storage administrators improve the efficiency of
disk utilization. It is hard to quantify exactly the efficiency rates in the UNIX/Windows space,
since use of such tools is relatively new. However, in the mainframe world with DFSMS,
efficiency rates of over 95% disk utilization are common. If in the UNIX/Windows space, we
can conservatively assume that we could achieve rates of 80%, then Figure 1-4 shows the
cost savings that might be possible in our examples above.

Figure 1-5 Predicted savings from managed storage versus unmanaged storage
One key piece of information is shown in Figure 1-4. By using SRM software to improve our
utilization, then, using existing storage, we can absorb 27 months of growth in the Windows
example, or seven months of growth in the enterprise storage example - this represents a
significant cost benefit.

1.2.3 Unmanaged storage costs too much, and the scope is large
Need for Storage Management
"Most of our clients report that they can afford to
buy storage, but they can't manage it."
Nick Allen, Vice President, Research Director, Gartner
"It's not important how much storage you have,
it's how much managed storage you have. If
you don't know what you've got, how do you
know what you need?"
Michael Karp, Enterprise Management Associates
ibm.com/redbooks
Figure 1-6 The need for storage management
Today, when the user calls and says “my application ran out of disk space and just stopped!”
administrators (storage administrators, network administrators, application administrators, or
platform administrators) have to scramble to get the application running again.
Administrators have to:
򐂰 Scan the filesystems for stale or duplicate files, and delete them
򐂰 Look at the application to see if some data can be archived, and try to archive it
򐂰 Or else, quickly order more disk for earliest delivery, paying whatever the vendor demands
Meantime, the application is down, the company is losing money, and user satisfaction is very
low. Not being able to track the space used against space available is very expensive.
Current tools and processes
The current approach to managing storage resources typically involves manual processes
and custom scripts. For every platform, there might be a custom script to list the storage
available on individual servers. The storage administrators who manage these scripts must
run them periodically, and generally do not have the time to analyze the results, and
sometimes miss critical situations.
To find the stale files, duplicate files, or inappropriate files, the storage administrator would
have to get write access to all the servers in the environment, write the custom scripts, debug
them, run them regularly and review the resulting information manually, and then try to act on
it, while trying to perform his normal duties. The scripts also have to be maintained so that
they cater for new servers, new LUNs or volumes, new filesystems, new applications, new
policies, and so on. Doing all this manually is very difficult, if not almost impossible.

IBM Tivoli Storage Resource Manager: A Practical Introduction
Looking forward
Based on various studies of estimated system and data growth, we proposed the following
projection of the number of filesystems and amounts of storage that would have to be
managed by a typical large company in 2004.

Figure 1-7 Scope of the problem - total storage, total number of filesystems
In this projection we used 100 GB for the size of the average UNIX host today, 25 GB for the
average Windows host, and 150 TB of storage as a target for the total storage in the average
large company. We also made some assumptions as to the number of filesystems per
UNIX/Windows host. We believe that this is a quite conservative projection. If you use larger
numbers, then the numbers are even more daunting. Nonetheless, the projection illustrates
the point: by 2004, an average large company will be managing:
򐂰 7,500 filesystems
򐂰 150TBs of storage
򐂰 3,750 servers
How many people would I need to manage storage?
The answer to this question depends on the tools used to manage storage.

Figure 1-8 Number and cost of storage administrators needed
In trying to project the staffing cost for storage administration (and only for administering disk)
we started with Figure 1-7, made some assumptions, and looked at the numbers. We made
two different projections - one based on the number of Gigabytes of storage that an
administrator would administer with today’s tools, and one based on the number of servers
that an administrator could manage. The assumptions were conservative.
For storage, we assumed that UNIX administrators could handle 3 TB, and Windows
administrators could handle 1 TB, and that the weighted average cost of an administrator was
$100,000 per year. Adjust your own model according to your own situation, since salary costs
vary greatly among different countries and cities, as well as within industry.
Even with conservative assumptions, administering disk will cost a lot of money. These
numbers are significant, and in parallel the situation facing the IT service industry in 1985
before the introduction of storage management tools on the mainframe. After DFSMS was
introduced to the mainframe, storage administration labor costs dropped by 90%.
Fewer studies have yet been performed in the UNIX/Windows world on the impact of storage
management tools on storage administration costs. If we were to use 45% (half the savings
achieved in the mainframe world) as a working guideline for the savings, we could achieve in
the UNIX/Windows world, given the large numbers, and the figure would be substantial.
1.2.4 Storage management functions defined
So far, we have discussed only administering disk. Storage administration covers other areas
as well:
򐂰 Platform administration
򐂰 Backup and recovery
14
IBM Tivoli Storage Resource Manager: A Practical Introduction
򐂰 Business Continuance and Disaster Recovery
Platform administration
A company with hundreds of UNIX and thousands of Windows servers across different
business units has thousands of separate filesystems to administer. Managing that many
anything is difficult. A growing percentage of companies have started consolidating storage
into SANs, but they still have the same number of storage entities to manage. Filesystems are
still assigned to individual application servers, and storage on the FC storage frame is
logically segregated.
Some companies have FC storage pools, NAS storage pools, and direct-attached storage
environments. Each FC storage pool is managed by its own storage manager. Each NAS pool
has its own manager. Each small group of direct-attached servers has its own platform
administrator. These labor costs can be at the user department level, at the division IT level,
or at the corporate IT level. The costs are hard to aggregate, but are large.
Backup and recovery
Whether your backup and recovery is decentralized or centralized, the same tasks have to be
performed. These tasks are almost always performed manually.

򐂰 Monitor job stream
򐂰 Fix Errors
Recovery:
򐂰 Extract tapes from library, send offsite
򐂰 Recover tapes from offsite as needed
򐂰 Load those tapes into library, perform
recovery
In either case, the corporation is paying for IT professionals to manage the backup and
recovery function. Dollars are either hidden in parts of individual’s salaries across the many
different departmental budgets, or prominently displayed (i.e. a large figure) in a centralized
budget.
Business Continuance and Disaster Recovery
The Disaster Recovery and Business Continuance function continues to be prominent. This
function involves planning a recovery from a site or facility disaster, including people,
processes, facilities, and IT infrastructure. With formerly two to three people, today,
companies have staffed up this function to five to ten people who report (in many cases)
directly to the CEO.
1.2.5 Architecture for a suite of Storage Management solutions
Figure 1-9 shows the storage infrastructure functions from the low level device solutions up to
the business management level.
The current set of Tivoli solutions already provide many of the functions in the Business
Management section (that is, Systems Management, Storage Management, and Security
Management).
Chapter 1. Introduction to Storage Resource Management
15
IBM Tivoli Storage Manager, IBM Tivoli Storage Resource Manager, and IBM Tivoli Storage
Area Network Manager provide the functionality for the middle Storage Resource
Management layer. They interoperate with and utilize the lower level Storage Infrastructure
layer applications. These are often vendor-specific solutions, such as individual Element
Managers or Replication Solutions. These also encompass some upcoming products from
IBM, such as for Virtualization.

1.2.6 Standards and Storage Resource Management tools
For the storage users community (both vendors and buyers), standards form the basis for
compatibility and interpretability:
򐂰 Standards enable buyers to pick the solutions they want to implement with the knowledge
that today’s solution will be interoperable with tomorrow’s solution, and that existing
hardware investments will be protected as the environments are extended.
򐂰 For vendors, standards give the confidence that a wide market exists for their solutions,
and lower the costs of compatibility testing.
As the Storage Resource Management tools start to implement reporting based on the
storage devices themselves, not just reporting from the operating systems view, the tools
need to know how to get this data from various storage devices. In the past and often still
today, such information was only accessible through vendor APIs as there still is no
standardized way to extract data from the storage device. For example, if the Storage
Resource Management tool wants to report where in the storage array particular data is
located, it will need to communicate to the storage device through a custom API to get this
information. This approach has several drawbacks:
16
IBM Tivoli Storage Resource Manager: A Practical Introduction
򐂰 When the vendor changes the API, the management application has to change also.
򐂰 Higher development costs, because of the diversity of storage devices.
򐂰 Slow time to market in case of limited development resources.
򐂰 Some storage vendors do not publish the APIs, resulting in either unsupported devices, or
need to make special arrangements with those vendors.
򐂰 Management application vendor must maintain a large number of different specifications.
Standards organizations and standards
Today, there are at least 10 organizations involved in creating standards for storage, storage
management, SAN management, and interpretability. Figure 1-10 shows the key
organizations involved in developing and promoting standards relating to storage, storage
management, and SAN management, and the relevant standards for which they are
responsible.

Key standards for Storage Resource Management are:

Standards. This includes the CIM Device Model for Storage, which at the time of writing
was version 2.7.2 for the CIM schema
򐂰 Storage Networking Industry Association (SNIA) Storage Management Initiative (SMI)
Specification
CIM/WEB management model
CIM was developed as part of the Web-Based Enterprise Management (WBEM) initiative by
the Desktop Management Task Force (DMTF) to simplify management of distributed systems.
Chapter 1. Introduction to Storage Resource Management
17
It uses an object-oriented approach to describe management information, and the description
(data model) is platform- and vendor-independent. CIM profiles have already been developed
for some devices, such as Storage Subsystems, Fibre Channel switches, and NAS devices.
IBM’s intent is to support CIM-based management as and when device manufacturers deliver
CIM-based management interfaces.
CIM/WBEM technology uses a powerful human and machine readable language called the
managed object format (MOF) to precisely specify object models. Compilers can be
developed to read MOF files and automatically generate data type definitions, interface stubs,
and GUI constructs to be inserted into management applications.
SMIS object models are extensible, as explained in “SMI Specification” on page 18, enabling
easy addition of new devices and functionality to the model, and allowing vendor-unique
extensions for added-value functionality.
Figure 1-11 shows the components of the SMIS/CIM/WBEM model.

Figure 1-12 SMI Specification
The idea behind SMIS is to standardize the management interfaces so that management
applications can utilize these and provide cross device management. This means that a
newly introduced device can be immediately managed as it will conform to the standards.
SMIS extends CIM/WBEM with the following:
򐂰 A single management transport
Within the WBEM architecture, the CIM-XML over HTTP protocol was selected for this
transport in SMIS
򐂰 A complete, unified, and rigidly specified object model.
SMIS defines “profiles” and “recipes” within the CIM that enables a management client to
reliably utilize a component vendor’s implementation of the standard such as the control of
LUNs and Zones in the context of a SAN
򐂰 Consistent use of durable names
As a storage network configuration evolves and is reconfigured, key long-lived resources
like disk volumes must be uniquely and consistently identified over time
򐂰 Rigorously documented client implementation considerations
SMIS provides client developers with vital information for traversing CIM classes within a
device/subsystem and between devices/subsystems such that complex storage
networking topologies can be successfully mapped and reliably controlled
򐂰 An automated discovery system
SMIS compliant products when introduced in a SAN environment will automatically
announce their presence and capabilities to other constituents
򐂰 Resource Locking
Chapter 1. Introduction to Storage Resource Management
19
SMIS compliant management applications from multiple vendors can exist in the same
storage device or SAN and cooperatively share resources through a lock manager
The models and protocols in the SMIS implementation are platform-independent, enabling
application development for any platform, and enabling them to run on different platforms. The
SNIA will also provide interpretability tests which will help vendors to test their applications
and devices if they conform to the standard.
Integrating legacy devices into the CIM model
As these standards are still evolving, we cannot expect that all devices will support the native
CIM interface, and because of this, the SMIS is introducing CIM agents and CIM object
managers (CIM/OM). The agents and object managers bridge proprietary device
management to device management models and protocols used by SMIS. The agent is used
for one device and an object manager for a set of devices. This type of operation is also called
a proxy model and is shown in Figure 1-13.

Figure 1-13 CIM Agent & CIM Object Manager
The CIM Agent or CIM Object Manager (CIM/OM) will translate a proprietary management
interface to the CIM interface. An example of a CIM/OM is the IBM CIM Object Manager for
the IBM TotalStorage Enterprise Storage Server (ESS).
In the future, more and more devices will be native CIM compliant, and will therefore have a
built-in Agent as shown in the “Embedded Model” in Figure 1-13.
When widely adopted, SMIS will streamline the way that the entire storage industry deals with
management. Management application developers will no longer have to integrate
incompatible feature-poor interfaces into their products. Component developers will no longer
have to “push” their unique interface functionality to applications developers. Instead, both will
be better able to concentrate on developing features and functions that have value to

end-users. Ultimately, faced with reduced costs for management, end-users will be able to
adopt storage-networking technology faster and build larger, more powerful networks.

1.3 Objectives of Storage Resource Management
Customers want to achieve the following goals (shown in Figure 1-14) with Storage Resource
Management tools.
Objectives of Storage Resource Management
Lower the cost of storage acquisition
Lower the cost of storage management
use industry standards for managing storage devices (eg CIM/WBEM)
manage all storage with one application
manage across the boundaries of the physical devices
Support business requirements as seamlessly as possible
efficiently store all data

Figure 1-14 Objectives of Storage Resource Management
IBM Tivoli Storage Resource Manager is enabled for CIM/WBEM based storage management
and as more and more devices become CIM enabled, it will be ready to manage them,
enabling a single point of management control for different storage devices.
IBM Tivoli Storage Resource Manager addresses the goals identified above, and offers
storage administrators the reporting tools needed to understand:
How much space is allocated to each application server, and how much is being used?
How fast data is growing (for a server, a filesystem, a type of data, etc.)?
How much space is being wasted?
How much space is available across a business unit or the enterprise?
How the data is distributed inside storage device (as of time of writing this was only
available for IBM ESS)?

Summary
We have demonstrated that:
򐂰 Storage and data are growing rapidly.
򐂰 Storage inefficiencies are rife.
򐂰 Storage costs a lot, even as the cost of storage decreases.
򐂰 Storage management costs a lot.
򐂰 Companies cannot continue to manage storage and data the old way (managing
individual components) and be successful. Companies must adopt new tools to manage
storage and data.

Introduction to IBM Tivoli
Storage Resource Manager
This chapter introduces and positions IBM Tivoli Storage Resource Manager - its
architecture, components, and functionality.
Tivoli Storage Resource Manager monitors storage assets, capacity, and usage across an
enterprise. Tivoli Storage Resource Manager can look at:
򐂰 Storage from a host perspective: Manage all the host-attached storage, capacity and
consumption attributed to filesystems, users, directories, and files
򐂰 Storage from an application perspective: Monitor and manage the storage activity inside
different database entities including instance, tablespace, and table
򐂰 Storage utilization and provide chargeback information.
Tivoli Storage Resource Manager provides over 300 standardized reports (and the ability to
customize your own reports) about filesystems, databases, and storage infrastructure. These
reports provide the storage administrator information about:

The Tivoli Storage Resource Manager Server:
򐂰 Controls the discovery, reporting, and Alert functions
򐂰 Stores all data in the central repository
򐂰 Issues commands to Agents for jobs (either scheduled or ad hoc)
򐂰 Receives requests from the user interface clients for information, and retrieves the
requested information from the central data repository.
򐂰 Extends filesystems automatically
򐂰 Reports on the IBM TotalStorage Enterprise Storage Server (ESS) and can also provide
LUN provisioning
An RDBMS (either locally or remote) manages the repository of data collected from the
Agents, and the reporting and monitoring capabilities defined by the users.
WWW Server
The Web Server is optional, and handles communications to allow remote Web access to the
Server. The WWW Server can run on the same physical server as the SRM Server.
SRM Agent (on a Managed System)
The Agent runs Probes and Scans, collects storage-related information from the managed
system, and forwards it to the Manager to be stored in the database repository, and acted on
Chapter 2. Introduction to IBM Tivoli Storage Resource Manager
27
if so defined. An Agent is required for every host system to be monitored, with the exception
of NetWare and NAS devices.
Novell NetWare and NAS devices do not currently support locally installed Agents - they are
managed through an Agent installed on a machine that uses (accesses) the NetWare or NAS
device. The Agent will discover information on the volumes or filesystems that are accessible
to the Agent’s host.
The Agents are quite lightweight. Agents listen for commands from the host, and then perform
a Probe (against the operating system), and/or a Scan (against selected filesystems). Normal
operations might see one scheduled Scan per day or week, plus various ad hoc Scans.
Chapter 5, “Operations: Policy, Quotas, and Alerts” on page 159 provides details of Scans
and Probes.
Clients (direct-connected and Web connected)
Direct-connect Clients have the GUI to the Server installed locally. They communicate directly
to the Manager to perform administration, monitoring, and reporting. The Manager retrieves
information requested by the Clients from the database repository.
Web-connect clients use the WWW Server to access the user interface through a Web
browser. The Java administrative applet is downloaded to the Web Client machine and
presents the same user interface that Direct-connect Clients see.

– Perform administrative tasks and customize the Tivoli Storage Resource Manager
environment
– Create Groups, Profiles, Quotas, and Constraints
– Set Alerts
2.2 Enhancements to Tivoli Storage Resource Manager V 1.2
This section describes enhancements for IBM Tivoli Storage Resource Manager Version 1.2.
2.2.1 Automated filesystem extension
Filesystem extension allows you to create additional space in the local filesystems of
managed hosts. You can extend filesystems manually, or set up a policy to do it automatically.
Policy can be configured to extend filesystems at a specified time, or when the utilization
reaches a specified threshold. Filesystem extension is supported for JFS filesystems running
on AIX 5.1 and VxFS filesystems running on Sun Solaris 2.8. See 5.3.1, “Filesystem
extension and LUN provisioning” on page 200.
Chapter 2. Introduction to IBM Tivoli Storage Resource Manager
29
2.2.2 Enterprise Storage Server (ESS) integration
ESS Subsystem Reporting gathers and reports on IBM TotalStorage Enterprise Subsystem
(ESS) devices that can be seen in the CIM/OM. IBM Tivoli Storage Resource Manager can
discover ESS subsystems, and report on them. The new subsystem reports show the
capacity, controllers, disks, and LUNs of an ESS, and their relationships to computers and
filesystems within a network. See also 6.3.1, “ESS Reporting” on page 297. ESS LUN
provisioning provides filesystem extension using the ESS Common Information Model/Object
Manager (CIM/OM) to interact with ESS subsystems. CIM/OM was introduced in “CIM/WEB
management model” on page 17. This function allows for the automatic provisioning of
Enterprise Storage Server LUNs when there is not enough space available in a volume group
to extend a filesystem. For more information on ESS LUN provisioning see 5.3.1, “Filesystem
extension and LUN provisioning” on page 200.
2.2.3 TEC integration
You can now choose to send Alerts to the Tivoli Enterprise Console ® (TEC) when they are
triggered. The TEC administrator can write correlation and automation rules to analyze IBM
Tivoli Storage Resource Manager events according to the event definitions specified in the
BAROC file (provided by IBM Tivoli Storage Resource Manager). It also performs responses
such as sending further notification, creating or updating trouble tickets, running programs,
etc. See Chapter 8., “Integration with Tivoli Enterprise Console” on page 411.
2.2.4 Cloudscape
Interbase (formerly shipped for a database repository with IBM Tivoli Storage Resource
Manager) has been replaced with IBM’s Cloudscape database for use as an IBM Tivoli
Storage Resource Manager repository. You can easily install this lightweight database and
use it for demonstration purposes, trial licenses, test environments, and so on. See the IBM
Tivoli Storage Resource Manager Installation Guide, GC32-9066, for more information about
Cloudscape support.
2.2.5 UDB/DB2 support
IBM Tivoli Storage Resource Manager for Databases now supports DB2 UDB 7.1 or higher,
including distributed DB2 databases.
2.3 Justification for IBM Tivoli Storage Resource Manager
An investment in Tivoli Storage Resource Manager is typically justified by:
򐂰 Reducing costs (disk, and storage administration)
򐂰 Enhancing revenue (keeping data available to applications all the time)
When you first run Tivoli Storage Resource Manager (and Tivoli Storage Resource Manager
for Databases) against your servers and disks, filesystems and databases, you find out:
򐂰 What space is used on what servers and storage
򐂰 What files are using that space
򐂰 Which database applications have sufficient space, and which do not
Customers typically find that utilization percentage across the enterprise is low - typically less
than 50%. Therefore, generally the initial focus is on housecleaning - delete stale, old, or
inappropriate files. After housecleaning, storage utilization should now have reached even
lower levels - maybe 40% this time. After completing this step, you can continue to more long

term goals such as planning for future growth and storage purchases, and implementing
appropriate policies and reporting to ensure storage use remains efficient.
2.3.1 Improving storage return on investment
Tivoli Storage Resource Manager can improve the storage return on investment by:
򐂰 Delaying purchases of disk - After performing housecleaning, you can satisfy the demand
for more storage from existing (now freed-up) disk. Depending on your particular situation,
you may not need to buy more disk for 6 to 24 months.
򐂰 Lowering the storage growth rate - Because you now are monitoring and keeping better
control of your storage according to policies in place, it should grow at a lower rate than
before.
򐂰 Lowering disk costs - With Tivoli Storage Resource Manager, you will know what the real
quarter-to-quarter growth rates actually are, instead of approximating (best-effort basis)
once per year. You can project your annual demand with a good degree of accuracy, and
can negotiate an annual contract with periodic deliveries, at a price lower than you would
have paid for periodic emergency purchases.
򐂰 Lowering storage management costs - The manual effort is greatly reduced as most
functions, such as gathering the information and analyzing it, are automated. Automated
Alerts can be set up so the administrator only needs to get involved in exception
conditions.
Enhancing revenue
Before using Tivoli Storage Resource Manager to manage your storage, it was difficult to get
advance warning of out-of-space conditions on critical application servers. If an application
did run out of storage on a server, it would typically just stop. This means revenue generated
from that application or the service provided by it also stopped, and this incurred a high cost
to fix it, as fixing unplanned outages fast is usually expensive.
With Tivoli Storage Resource Manager, applications will not run out of storage. You will know
when they need more storage, and can get it at a reasonable cost before an outage occurs.
You will avoid the loss of revenue and services, plus the additional costs associated with
unplanned outages.

2.4.1 Basic menu displays
Figure 2-5 shows the main menu for IBM Tivoli Storage Resource Manager. You can see that
the Agents configured show under the Agents entry. The green dot shows that the Agent is
communicating with the Server. The red crossed circle indicates that CLYDE is down. The red
triangle next to the Agent SUSE82-1 indicates that the Agent on that system is not reachable.
The red crossed square next to the Agent BANDA indicates that it was connected, but
currently there is an update for Tivoli Storage Resource Manager agent running. This display
thus shows a quick summary of the state of each Agent.

2.4.2 Discover and monitor Agents, disks, filesystems, and databases
Tivoli Storage Resource Manager uses three methods to discover information about the
assets in the storage environment: Pings, Probes, and Scans. These are typically set up to
run automatically as scheduled tasks. You can define different Ping, Probe, and Scan jobs to
run against different Agents or groups of Agents (for example, to run a regular Probe of all
Windows systems) according to your particular requirements.
Pings
A Ping is a standard ICMP Ping which checks registered Agents for availability. If an Agent
does not respond to a Ping (or a pre-defined number of Pings) you can set up an Alert to take
some action. The actions could be one, any, or all of:
򐂰
򐂰
򐂰
򐂰
򐂰
SNMP trap
Notification at login
Entry in the Windows event log
Run a script
Send e-mail to a specified user(s)
Pings are used to generate Availability Reports, which lists the percentage of times a
computer has responded to the Ping. An example of an Availability Report for Ping is shown
in Figure 2-7. Availability Reports are discussed in detail in 6.2.3, “Availability Reporting” on
page 262.
Chapter 2. Introduction to IBM Tivoli Storage Resource Manager
35
Figure 2-7 Availability Report - Ping
Probes
Probes are used to gather information about the assets and system resources of monitored
servers, such as processor count and speed, memory size, disk count and size, filesystems,
etc. If Tivoli Storage Resource Manager for Databases is licensed, then Probes also gather
information about the files, instances, logs, and objects that makeup the monitored
databases. The data collected by the Probe process is used in the Assets Reports described
in 6.2.1, “Asset Reporting” on page 252.
Figure 2-8 shows an Asset report for detected disks.
Figure 2-8 Asset Report of discovered disks
Figure 2-9 shows an Asset Report for detected database tablespaces.
36
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 2-9 Asset Report of database tablespaces
Scans
The Scan process is used to gather statistics about usage and trends of the server storage. If
Tivoli Storage Resource Manager for Databases is licensed, then Scans also gather
information about the storage usage and trends within the monitored databases. Data
collected by the Scan jobs are tailored by Profiles. Results of Scan jobs are stored in the
enterprise repository. This data supplies the data for the Capacity, Usage, Usage Violations,
and Backup Reporting functions. These reports can be scheduled to run regularly, or they can
be run ad hoc by the administrator.
Profiles limit the scanning according to the parameters specified in the Profile. Profiles are
used in Scan jobs to specify what file patterns will be scanned, what attributes will be
gathered, what summary view will be available in reports and the retention period for the
statistics. Tivoli Storage Resource Manager supplies a number of default Profiles which can
be used, or additional Profiles can be defined. Table 5-1 on page 180 shows the default
Profiles provided. Some of these include:
򐂰 Largest files - Gathers statistics on the largest files
򐂰 Largest directories - Gathers statistics on the largest directories
򐂰 Most at risk - Gathers statistics on the files that have been modified the longest time ago
and have not been backed up since modified (Windows Agents only)
Figure 2-10 shows a sample of a report produced from data collected in Scans.
Chapter 2. Introduction to IBM Tivoli Storage Resource Manager
37
Figure 2-10 Summary View - by filesystem, disk space used and disk space free
This report shows a list of the filesystems on each Agent, the amount of space used in each,
expressed in bytes and as a percentage, the amount of free space, and the total capacity
available in the filesystem.
2.4.3 Reporting
Reporting in Tivoli Storage Resource Manager is very rich, with over 300 pre-defined views,
and the capability to customize those standard views, save the custom report, and add it to
your menu for scheduled or ad hoc reports. You can also create your own individual reports
according to particular needs and set them to run as needed, or in batch (regularly). Reports
can be produced in table format or a variety of charting (graph) views. You can export reports
to CSV or HTML formats for external usage.
Reports are generated against data already in the repository. A common practice is to
schedule Scans and Probes just before running reports.
Reporting can be done at almost any level in the system, from the enterprise down to a
specific entity and any level in between. Figure 2-6 on page 34 shows a high-level summary
report. Or, you can drill down to something very specific. Figure 2-11 is an example of a
38
IBM Tivoli Storage Resource Manager: A Practical Introduction
lower-level report, where the administrator has focussed on a particular Agent, BANDA, to
look at a particular disk on a particular controller.
Figure 2-11 Asset Report - BANDA assets
Reports can be produced either system-wide or grouped into views, such as by computer, or
OS type.
Restriction: Currently, there is a maximum of 32,767 (216 -1) rows per report. Therefore,
you cannot produce a report Tivoli Storage Resource Manager to list all the .HTM files in a
directory containing a million files. However, you can (and it would be more productive to
do so) produce a report of the 20 largest files in the directory, or the 20 oldest files, for
example.
Tivoli Storage Resource Manager allows you to group information about similar entities (disk,
filesystems, etc.) from different servers or business units into a summary report, so that
business and technology administrators can manage an enterprise infrastructure. Or, you can
summarize information from a specific server - the flexibility and choice of configuration is
entirely up to the administrator.
You can report as at a point in time, or produce a historical report, showing storage growth
trends over time. Tivoli Storage Resource Manager reporting lets you track actual demand for
disk over time, and then use this information to forecast future demand for the next quarter,
two quarters, year, etc. Figure 2-12 is an example of a historical report, showing a graph of
the number of files on the C drive on the Agent WISLA.
Chapter 2. Introduction to IBM Tivoli Storage Resource Manager
39
Figure 2-12 Historical report of filesystem utilization
Tivoli Storage Resource Manager has three basic types of reports:
򐂰 Computers and filesystems
򐂰 Databases (if the module is licensed)
򐂰 Chargeback (if the module is licensed)
Reporting categories
Major reporting categories for filesystems and databases are:
򐂰 Assets Reporting uses the data collected Probes to build a hardware inventory of the
storage assets. You can then navigate through a hierarchical view of the assets by drilling
down through computers, controllers, disks, filesystems, directories, and exports. For
database reporting, information on instances, databases, tables, and data files is
presented for reporting.
򐂰 Storage Subsystems Reporting provides information shows storage capacity at a
computer, filesystem, storage subsystem, LUN, and disk level. These reports also enable
you to view the relationships among the components of a storage subsystem. Storage
Subsystem Reporting is available at the time of writing for the IBM TotalStorage Enterprise
Storage Server (ESS)
򐂰 Availability Reporting shows responses to Ping jobs, as well as computer uptime.
򐂰 Capacity Reporting shows how much storage capacity is installed, how much of the
installed capacity is being used, and how much is available for future growth. Reporting is
done by disk and filesystem, and for databases, by database.
򐂰 Usage Reporting shows the usage and growth of storage consumption, grouped by
filesystem, and computers, individual users, or enterprise-wide.
򐂰 Usage Violation Reporting shows violations to the corporate storage usage policies, as
defined through Tivoli Storage Resource Manager. Violations are either of Quota (defining
40
IBM Tivoli Storage Resource Manager: A Practical Introduction
how much storage a user or group of users is allowed) or Constraint (defining which file
types, owners and file sizes are allowed on a computer or storage entity). You can define
what action should be taken when a violation is detected - for example, SNMP trap, e-mail,
or running a user-written script.
򐂰 Backup Reporting identifies files which are at risk because they have not been backed up.
Reporting on the Web
It is easy to customize Tivoli Storage Resource Manager to set up a reports Web site, so that
anyone in the organization can view selected reports through their browser. Section 6.7,
“Setting up a reports Web site” on page 361 explains how to do this. Figure 2-13 shows an
example of a simple Web site to view Storage Resource Management reports.
Figure 2-13 SRM Reports on the Web
2.4.4 Alerts
An Alert defines an action to be performed if a particular event occurs or condition is found.
Alerts can be set on physical objects (computers and disks) or a logical objects (filesystems,
directories, users, databases, and OS user groups). Alerts can tell you, for instance, if a disk
has a lot of recent defects, or if a filesystem or database is approaching capacity.
Alerts on computers and disks come from the output of Probe jobs and are generated for
each object that meets the triggering condition. If you have specified a triggered action
(running a script, sending an e-mail, etc.) then that action will happen if the condition is met.
Alerts on filesystems, directories, users, and OS user groups come from the combined output
of a Probe and a Scan. Again, if you have specified an action, that action will be performed if
the condition is met.
Chapter 2. Introduction to IBM Tivoli Storage Resource Manager
41
An Alert will register in the Alert log, plus you can also define one, some or all of the following
actions to be performed in addition:
򐂰
򐂰
򐂰
򐂰
򐂰
򐂰
Send an e-mail indicating the nature of the Alert.
Run a specific script with relevant parameters supplied from the content of the Alert.
Make an entry into the Windows event log.
Pop up next time the user logs in to Tivoli Storage Resource Manager.
Send an SNMP trap.
Log a TEC event
Figure 2-14 shows the Alert Log. The entries Alert Log, All, Computer, and Filesystem are in
red, signifying that an Alert threshold has been reached. Drilling down on Computer, you can
see the details of the Alert. We can see it was caused by the system VMWARE2KSRV1 being
unreachable.
Figure 2-14 Alert Log and details
Refer to 5.2, “OS Alerts” on page 189 for details on alerts.
2.4.5 Chargeback: Charging for storage usage
Through the optional Tivoli Storage Resource Manager for Chargeback product, Tivoli
Storage Resource Manager provides the ability to produce Chargeback information for
storage usage. The following items can have charges allocated against them:
򐂰
򐂰
򐂰
򐂰
Operating system storage by user
Operating system disk capacity by computer
Storage usage by database user
Total size by database tablespace
Tivoli Storage Resource Manager can directly produce an invoice or create a file in CIMS
format. CIMS is a set of resource accounting tools that allow you to track, manage, allocate,
and charge for IT resources and costs. For more information on CIMS see the Web site:
http://www.cims.com.
Chargeback is a very powerful tool for raising the awareness within the organization of the
cost of storage, and the need to have the appropriate tools and processes in place to manage
storage effectively and efficiently.
Example 2-1 shows a Chargeback Report based on disk usage by user.

Tivoli Storage Resource Manager consists of the following components:
򐂰 Server acts as the center for all management operations. All requests from clients are
sent to the SRM server, and the server then retrieves data from the repository and returns
it to the client. With this data, users can construct and display the reports. The Server also
directs the Agent activity through its job scheduling component.
򐂰 Database Repository is used to store the collected data from the Agents.
򐂰 WWW Server is optional, and provides communications for remote Web access to the
Server. The WWW Server can run on the same physical system as the Tivoli Storage
Resource Manager Server.
򐂰 Managed Systems run the Tivoli Storage Resource Manager Agent code, which is used
to gather the information about the managed server, its storage, and managed
applications.
򐂰 Direct-connect Clients have the GUI to the Server installed locally. They communicate
directly with the Server to perform administration, monitoring, and reporting.
򐂰 Scheduled Batch Reports are jobs which prepare reports based on collected data from
the Managed Systems, which are scheduled to run automatically. The reports will be
generated using the data residing in the database.
48
IBM Tivoli Storage Resource Manager: A Practical Introduction
򐂰 Web Connect Clients use the WWW Server to access the GUI through a Web browser.
The Java administrative applet is downloaded to the Web Client machine and presents the
same user interface as for the Direct Connect Clients.
3.2 IBM Tivoli Storage Resource Manager Server
The Server component is the main part of IBM Tivoli Storage Resource Manager. The Server
is responsible for the following roles as shown in Figure 3-2.

Figure 3-2 IBM Tivoli Storage Resource Manager Server roles
򐂰 Monitoring
– Discovery - The Server searches the network to discover machines which do not have
Agent code installed (that is, not yet being monitored by IBM Tivoli Storage Resource
Manager). It will add them to the Unmanaged list (shown in Figure 3-3 on page 51) so
they can be potentially managed later. Only Windows systems in the same domain as
the IBM Tivoli Storage Resource Manager Server will be discovered.
– Probes - The Server will collect the inventory of storage assets of Managed Systems
(computers, controllers, disk driver, filesystems, logical units, etc.) and store it in the
database repository.
– Pings - The Server checks the availability of the Managed Systems by issuing TCP/IP
ping commands to the system. This function is not available for NAS devices and
NetWare servers.
– Scans - The Server Scans the Managed Systems to gather information on usage and
consumption.
Chapter 3. Deployment architecture
49
򐂰 Policy Management
– Quotas - The Quota check is performed based on the results of the Scans. Quotas
define the consumption level for filesystems, computers, and network. Quotas can be
run from the GUI, or they can be scheduled to run automatically. The data used for
Quota checking resides in the database. To achieve the most accurate Quota checking,
you need to schedule the Scan job before performing Quota check.
– Constraints - During a Scan, the Server will also perform a Constraint check on the
results. Constraints can be used to define what are acceptable and unacceptable file
types, file sizes, and file owners on Managed Systems.
– Scheduled Actions - You can schedule execution of a script against Managed Systems.
The script can be use any kind of command-shell, batch programming language of
third party tool, which can be invoked through a command line interface and is valid for
execution on the Agent.
򐂰 Alerts
– Alerts - After a Scan the Server will issue Alerts related to the Alert Threshold defined.
The Server roles described above are covered in more detail in Chapter 5, “Operations:
Policy, Quotas, and Alerts” on page 159.
All Storage Resource Management operations are controlled from the Server side. The
Server communicates with the Agents (Managed Systems) when it is performing those tasks.
No managed tasks are performed on the Agent itself. The Agent is just performing the Scans
and script execution on behalf of the Server. Also, all the communication with the database is
done on the Server side for performance reasons. The data is transmitted from the Agent to
the Server and the Server then stores it in the database repository. With such an approach,
there is no need for any database connectivity software on the Agents. Also, since the
Direct-connect Clients and Web Connect Clients for reporting request data through the
Server, rather than directly from the database, they also do not require any database
connectivity software installed.
As everything is controlled and run from the Server side, reliability and availability is a key
consideration for the system which is running the IBM Tivoli Storage Resource Manager
Server.
3.2.1 Discovery of unmanaged Windows systems
After the Tivoli Storage Resource Manager Server is installed it will try to find any unmanaged
Windows systems. In the process of discovery, one of the Agents installed in each Windows
domain or workgroup will identify other Windows systems. This data will be then transferred to
the Tivoli Storage Resource Manager Server, which will then query each system to determine
if they have Tivoli Storage Resource Manager Agent installed. If the system does not have the
Agent installed it will appear in the Unmanaged Systems list. To access this list, select IBM
Tivoli SRM -> Reporting -> Asset -> System-wide as shown in Figure 3-3.
50
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 3-3 Unmanaged systems
When you install the Tivoli Storage Resource Manager Server in a new environment, an
Agent is automatically installed on the same system as the Server. In this case after the initial
discovery job, all the Windows systems from the domain or workgroup of the Server system
will be displayed under Unmanaged Computers.
3.2.2 Scripts
Scripts are executed as a result of either of the following events:
򐂰 Scheduled actions - Batch Reports
򐂰 Alerts - An Alert can trigger an action, which can be a script
How are scripts run?
During the installation process of the Server and Agents, the \scripts directory under the
installation directory is created. The default directory is:
򐂰 Windows: \Program directory\Tivoli\TSRM
򐂰 UNIX: /opt/Tivoli/TSRM or /usr/Tivoli/TSRM
The following steps explain how scripts are run when they are triggered:
򐂰 The Server looks in its local \scripts directory.
򐂰 If the script with the required name is in that directory, the Server will load the script, and
send it to the Agent where it is designated to run.
򐂰 The Agent receives the script, saves it into a temporary file, and runs it.
򐂰 After the script is finished, the temporary file on the Agent is deleted.
Chapter 3. Deployment architecture
51
Note: When running a script against a NAS device or Novell NetWare servers, the
script is run on the Agent assigned to the filesystem where the triggered condition
occurred.
There are two possible scenarios where the script may not run from the Server:
򐂰 The script already exists on the Agent. In this case the Agent will run the local script
directly instead. The Agent is always checked first to see if it has a local copy, before
running it from the Server.
򐂰 You did not check the Agent may run scripts sent by server option during the
installation process as described in 4.3.3, “Installation of the Server code” on page 71:
Without this option set, Agents will not receive scripts from the server for execution.
Note: The advantage of setting the policy that Agents may run scripts from the Server is
that you can then install and maintain only one repository for all scripts. This can ease
the management of the scripts and it will also give you consistency.
3.3 IBM Tivoli Storage Resource Manager Agent
The Tivoli Storage Resource Manager Agent is responsible for the following tasks as shown
in Figure 3-4.

Figure 3-4 SRM Agent tasks
The Agent code is required on every system you want to manage. As the Agents
communicate through TCP/IP, the Managed System needs IP connectivity to the Server.
52
IBM Tivoli Storage Resource Manager: A Practical Introduction
The product uses the same code base for all three Agent types (OS, Database, and
Chargeback). Each of the Agents is activated by the licenses installed with the Manager code.
There are two exceptions on Agent placement:
򐂰 NAS devices - The monitoring of NAS devices is done through the systems using NAS
attached storage. Depending on the protocol used for filesystem access, those systems
can be either Windows or UNIX based systems.
Tip: It is recommended that you divide NAS exported filesystems among the Managed
Systems, which access the NAS device. This means that the workload of scanning and
probing is shared among the Agents.
򐂰 Novell NetWare servers - For retrieving the storage information from the servers and
volumes within NDS trees, you must install the Agent code on a Windows system where a
Novell NetWare client is already located. The Agent code uses native NetWare calls from
these systems. The requirements for a Windows Agent to scan NetWare systems are:
– Running Windows 2000 or Windows NT 4 SP4 and above
– Installed a NetWare Client
– Has access to the Novell NetWare servers and volumes within your environment. This
means that you must have a user ID with the correct access level to be able to perform
queries into the NDS trees.
3.4 Deployment considerations
In this section we will outline some considerations for deploying Tivoli Storage Resource
Manager installations. As Tivoli Storage Resource Manager supports various platforms for
the Server and Agent installations, the choice of Server platform will usually reflect the
platforms used in your environment. From the generally available information, and from our
experience in the lab installations, Tivoli Storage Resource Manager can coexist with virtually
any other server software.
A single Server instance can theoretically support more than 1000 Agents. Of course, the
load on the Server side will increase with the number of jobs defined. The load of the jobs on
the Server and Agents depends of the job definition. For example, a Scan which will look for
all files will run much longer, and be more CPU-intensive easier than a Scan which will look
for only particular file types.
The Agent should be installed on every system you want to manage. For managing NAS
devices and Novell NetWare servers, you need to install Agents on the systems using the
NAS and NetWare filesystems, as described in 3.3, “IBM Tivoli Storage Resource Manager
Agent” on page 52.
3.4.1 Repository database
All the configuration data and the data collected from Agent Scans is stored in the database
repository. By using this approach, all the data can be off-loaded to a separate database
server, since Tivoli Storage Resource Manager can use either a locally installed database or
a remote database repository. In the current edition of Tivoli Storage Resource Manager, the
repository can be local or remote using any of Microsoft SQL-Server, Oracle, and Sybase
SQL, or IBM DB2 UDB. The size of the database will vary upon the number of actions you are
taking in your Storage Resource Management environment. The size of the database will
depend on the following parameters:
Chapter 3. Deployment architecture
53
򐂰 The amount of historical data you keep
򐂰 The number of scanned files on each Managed System - for each scanned file, if a file
meets a Constraint criteria, a corresponding entry will be saved in the database.
򐂰 The type of jobs (for example, different type of Scans and Constraints) you are performing
򐂰 The number of systems you want to manage - i.e. Agents.
Tip: If possible, it is recommended that you use a separate system for the database
repository.
3.4.2 CIM/OM server placement
IBM Tivoli Storage Resource Manager provides a filesystem extension feature that can be
used to automatically increase filesystem capacity for managed hosts when utilization
reaches a specified level. This function allows for the automatic provisioning of Enterprise
Storage Server LUNs when there is not enough space available in a volume group to extend
a filesystem.
Filesystem extension uses the ESS Common Information Model/Object Manager (CIM/OM)
to interact with ESS subsystems. See “SMI Specification” on page 18 for more information on
CIM/OM. The IBM Tivoli Storage Resource Manager server communicates with the CIM/OM
server over an IP network using the HTTPS protocol. CIM/OMs installed on the same network
subnet as the IBM Tivoli Storage Resource Manager server can be automatically discovered.
The Service Location Protocol (SLP) is used to discover CIM/OMs.
For information about supported versions of the CIM/OM, see the IBM Tivoli Storage
Resource Manager Support Website at:
http://www-3.ibm.com/software/sysmgmt/products/support/IBMTivoliStorageResourceManager.html
Restriction: Automatic discovery is not supported for CIM/OMs installed on Sun Solaris or
HP-UX.
In our lab setup (Figure 3-5), the CIM/OM server is installed on a host called W2KADVTSM,
which talks to the ESS (ESSF20) through Ethernet. The IBM Tivoli Storage Resource
Manager server (W2KADVTSRM) makes an HTTPS connection over the network directly to
the CIM/OM server. Neither the IBM Tivoli Storage Resource Manager server, nor the
CIM/OM server need to be connected through Fibre Channel to the ESS.

If you just want ESS LUN reporting, then you do not need agents on the machines connected
to the ESS through Fibre Channel. For additional information (filesystems, devices, etc.) and
filesystem-extension and LUN provisioning, there must be an agent on the hosts connected to
the ESS.
3.4.3 NAS Agent placement
In Figure 3-6 we show an example of two Managed Systems, one on UNIX and one on
Windows using filesystems from a NAS device.

In this example we also divided the workload of scanning the NAS device over the two
systems. Depending on the size of the NAS filesystems, it is recommended to spread the
scanning workload among the systems running the Agent code.
NAS discovery
After you complete the installation of the Agents for the systems accessing the NAS devices,
initial discovery will be performed. The discovery job is sent to every managed UNIX Agent
and to one managed Windows Agent in each Windows domain:
򐂰 Windows - The Agent responsible for the discovery will issue an SNMP query to all the
Windows systems and NAS devices in the domain. If the Vendor Identification Number
matches a number defined in the file config\nas.config in the installation directory, the
system will be considered as a NAS device. In Example 3-1 you can see the nas.config file
from our lab installation.

After the initial Agent installation the entry for Microsoft is not present. We added the entry
to recognize the IBM NAS 200 device in our lab.
56
IBM Tivoli Storage Resource Manager: A Practical Introduction
Note: IBM NAS 200 is a Windows OS powered NAS device.
The 311 entry is the generic identification number for Windows systems so all Windows
machines will be discovered. You can later limit the login to the NAS devices (as shown in
Figure 3-7) selecting only the NAS device(s) you want to manage, and leave all the others
unselected. After discovering the NAS devices, the Agent will perform a login into each
device. By default, the password supplied during installation will be used. If the NAS
device requires a different password you can supply this password for each filesystem
separately as shown in “Configuration: General settings” on page 108.
Attention: If you decide to put the 311 entry in nas.config file, all Windows based
systems with SNMP enabled will be recognized as Other NAS devices, as shown in
Figure 3-7. This means that any Windows systems without installed Agents will no
longer show up under unmanaged devices. This could cause potential for a confusing
situation as you may think that all Windows based systems are managed, since they do
not appear in the unmanaged list.
Figure 3-7 After setting 311 for NAS discovery
Tip: Because of the mentioned reasons, if your Windows powered NAS device allows
installation of third party products, we recommend that you install the Agent on the
device itself.
򐂰 UNIX - All the Managed Systems that have filesystems mounted from other machines will
be used for discovering the NAS devices. The Agent uses the mount table (on Solaris,
auto-mount config files are also used) for the imported mounts. After this, it will perform an
SNMP query, and if the identification number returned is listed in the file nas.config, the
Chapter 3. Deployment architecture
57
device will be qualified as a NAS device. The NAS discovery process in UNIX will not
perform any logins into the NAS device.
Note: If the NAS device does not report back on the SNMP query, it will appear in the
Unmanaged Computers Report.
3.4.4 Novell NetWare Agent placement
Figure 3-8 shows Windows systems with the Novell NetWare client installed, accessing two

In this example, the data for the Novell NetWare server is extracted using Novell NDS
information. More than one NetWare server can be monitored from a single Managed System
with the Agent installed.
Attention: The system which will manage Novell Servers should have a user ID with
sufficient rights to perform queries to the NDS trees.
Novell NetWare discovery
The Novell NetWare servers are discovered from the Agents, which are installed on the
Windows system with the Novell NetWare client installed.

3.5 Deployment scenarios
In this section we will discuss several possible deployment scenarios.
3.5.1 Standalone Server installation with local database
The Tivoli Storage Resource Manager Server can be installed on a single system using a
local database. In this scenario, the Tivoli Storage Resource Manager Server and database
are resident on the same physical system. You can see this installation type in Figure 3-9.

Figure 3-9 Installation with local database
This type of installation can have certain scalability limitations as you need to take care of the
database growth and maintenance. This type of installation is available on all supported Tivoli
Storage Resource Manager Server platforms, providing the database product itself is
supported on that operating system. For example, Microsoft SQL-Server is only available for
Windows systems.
In our lab we performed this type of installation using a Windows 2000 Server system with
IBM DB2 Version 7.2 as the underlying database. The details of the installation are covered in
Chapter 4, “IBM Tivoli Storage Resource Manager installation” on page 67.
3.5.2 Standalone Server installation with remote database
In such a setup, the IBM Tivoli Storage Resource Manager server is installed on a supported
Server platform, accessing a remote database repository. In this case you can use different
platforms for the Server and the database. You can see this installation in Figure 3-10.

Figure 3-10 Installation with remote database
As the majority of enterprise database implementations are based on centralized
management, this setup allows Tivoli Storage Resource Manager to also participate in this
architecture by using a database on the centralized server. In this case, the management of
the database will be done by the DBAs.
3.5.3 Standby Server installation for HA using remote database
A standalone installation with a remote database can give us a certain level of high
availability. Typically, enterprise database servers are already protected using high availability
(HA) solutions, so we therefore only need to protect the Tivoli Storage Resource Manager
Server itself. One possibility would be to have a standby server (for example, a testing server)
which can be enabled in the event of a Tivoli Storage Resource Manager Server failure. This
setup is shown in Figure 3-11.

Figure 3-11 HA setup with remote database
The standby Server has to be installed with the same settings as the primary one, and it
needs to have access to the same database. Also, whenever you make changes to the
primary Server you need to make the same changes to the secondary Server.
In the event of a primary Server failure, you would only need to change the DNS record so
that the standby Server IP address will be resolved when Agents perform queries to the Tivoli
Storage Resource Manager Server.
In our lab environment we performed an installation using Oracle 8.1.7 on Windows 2000
Server to use as a database repository. We installed the Tivoli Storage Resource Manager
Server on another two Windows 2000 server systems. The details of installation are covered
in 4.8, “Manager HA install using remote Oracle database” on page 142.
3.5.4 Windows cluster install of IBM Tivoli Storage Resource Manager Server
In this case, the Tivoli Storage Resource Manager Server is installed on two Microsoft
Windows Server systems set up in a Microsoft Cluster Services (MSCS) environment. The
systems will use SAN attached storage for the shared disk resources. The database
repository will reside on a separate server. The setup is shown in Figure 3-12.

automatically maintains the consistency of the configuration.
In our lab environment we performed this installation using a remote database repository on
Oracle 8.1.7 on Windows 2000. We installed IBM Tivoli Storage Resource Manager Server
on cluster of two Windows 2000 Advanced Server systems. The details of the installation are
given in 4.7, “Microsoft Cluster installation” on page 123.
3.5.5 AIX cluster installation of IBM Tivoli Storage Resource Manager Server
In this case the installation of the IBM Tivoli Storage Resource Manager server will be
performed on two AIX server systems set up in an IBM HACMP environment. Both systems
will have the Tivoli Storage Resource Manager Server installed and they will use SAN
attached storage for the shared disk resources. The database repository will reside on a
separate server. The setup is shown in Figure 3-13.

򐂰 IBM DB2 7.2 with Fix Pack 8
򐂰 IBM Tivoli Storage Resource Manager Version 1.2
4.3.2 Database creation for repository
Before installing the Tivoli Storage Resource Manager Server, you need to create the
database for the data collected by the Server. You can either use a local database residing on
the same system as the Server itself, or a remote database residing on a different system.
These databases can be used remotely at the time of writing:

A DB2 database can be created using DB2 Control Center or by using command line tools.
We used the DB2 Control Center wizard to create the database, and accepted defaults for the
configuration settings. In our case we created a database called ITSRMDB for this
environment.
For the database which will be used as the repository, you also need to provide the JDBC
driver. Tivoli Storage Resource Manager uses the JDBC protocol to access the database.
70
IBM Tivoli Storage Resource Manager: A Practical Introduction
4.3.3 Installation of the Server code
To install the Server code in the Windows environment, run SETUP.EXE from the Windows
directory on the Tivoli Storage Resource Manager CD. Figure 4-4 shows the initial screen.
Figure 4-4 Initial installation screen
As this is a new install, the only possible selection is to install the IBM Tivoli SRM code. Click
Next to continue and the license agreement displays. Accept the license agreement and click
Next to continue. On the next window click Yes to confirm. You then select the components to
install, as shown in Figure 4-5.
Figure 4-5 Selecting product to install
As we are installing the Server code, we selected The Tivoli SRM Server and an Agent on
this machine.
Note: Whenever you install the Server code, the Agent code is also installed.
Chapter 4. IBM Tivoli Storage Resource Manager installation

After clicking Next, the license key screen in Figure 4-6 appears.
Figure 4-6 Enter licenses
Enter in the supplied licenses, depending on what you have bought for your organization.
Click Next to continue, and the database selection screen in Figure 4-7 displays.
Figure 4-7 Selecting the database engine for the repository
Select the database server which is available. In our setup, we used DB2 UDB as the
database repository.
After selecting the database repository click Next; you will see the service account screen
shown in Figure 4-8.
Figure 4-8 Creating account for running the service
72
IBM Tivoli Storage Resource Manager: A Practical Introduction
The installation program will create a system user ID which will be used for running the Tivoli
Storage Resource Manager Server service. Click OK to display the database selection
screen, as in Figure 4-9.
Figure 4-9 Selecting the database for the repository
The installation program will query the DB2 installation for existing databases and display
them. If the database you created for Tivoli Storage Resource Manager repository is listed,
you can select it by clicking on the name. Otherwise, you can type in the name under
Database Alias field. You also need to provide the database user name and password under
Connection information. Because the manager is accessing the database using JDBC you
need to specify the path to the JDBC driver in the JDBC driver.
Tip: JDBC is usually provided from the database vendor.
The JDBC driver for IBM DB2 is installed automatically with the database product itself.
Note: The setup for the other database engines will be slightly different, but you will still be
asked for the same type of information - that is, database name, user ID, and JDBC driver.
After providing all the necessary information, click Next and you will see the Repository
Creation Parameters screen shown in Figure 4-10.
Chapter 4. IBM Tivoli Storage Resource Manager installation
73
Figure 4-10 Repository parameters
On this screen you can specify the database schema and tablespace name.
Tip: We recommend that you accept the defaults for these two fields. Alternatively, you can
also use the naming convention that is used in your enterprise.
If you are using DB2 as the repository, you can also choose how you will manage the
database space:
򐂰 System Managed (SMS)
This option indicates that the space is managed by the OS. In this case you specify the
Container Directory, which is then managed by the system, and can grow as large as the
free space on the filesystem.
Tip: If you do not have in house database skills the System Managed approach is
recommended.
򐂰 Database managed (DMS)
This option means that the space is managed by the database. In this case you need to
specify the Container Directory, Container File and Size fields. Container file
specifies a filename for the repository, and Size is the predefined space for that file. You
can later change this by using the ALTER TABLESPACE command.
Tip: We recommended that you use meaningful names for Container Directory and
Container Filer at installation. This can help you in case you need to find the container
file.
The setup for other types of databases is similar. An example using Oracle is in step 9.,
“Install the Tivoli Storage Resource Manager Server on the primary server using the same
parameters as on the standby server.’’ on page 145. An example using MS SQL-Server is in
4.3.4, “Microsoft SQL-Server as repository’’ on page 78.
74
IBM Tivoli Storage Resource Manager: A Practical Introduction
After supplying all the necessary parameters click Next and you will see the parameter
screen similar to Figure 4-11.
Figure 4-11 Server setup
In this screen you need to provide the following information:
򐂰 Server name: The installation program will already display the host name of the computer
that you are installing on.
򐂰 Server port: The port on which the Server listens for the Agent requests.
򐂰 Agent port: The port on which the Agent listens for the requests.
Note: The ports 2078 and 2077 are registered with IANA (Internet Assigned Numbers
Authority), so we recommend you use them, unless they are already in use in your
network, you can change them. If you change them on the Manager installation, you
also need to change them on each host Agent installation.
The Agent port defined here is used for the local Agent which is installed along with the
Server installation. The port which is defined is registered in the database, and because of
that, each individual Agent could possibly use a different port (however, this is not
recommended).
򐂰 Agent should perform a SCAN when first brought up: With this option on, the host
Agent will perform an initial scan after installation.
򐂰 Agent may run scripts sent by server (in addition to local scripts): If this option is
selected, host Agents will accept scripts sent from the Manager, otherwise, they will only
run locally stored scripts. You can get more information about scripts in 3.2.2, “Scripts’’ on
page 51.
򐂰 Administrators Group: This is the name of the administrators users group. The default
value is Administrators, and can be changed if required for your organization. The
security roles are described in 4.6.1, “Security’’ on page 98.
After supplying all the needed information, click Next. You will see the NAS Discovery screen
shown in Figure 4-12.
Chapter 4. IBM Tivoli Storage Resource Manager installation
75
Figure 4-12 NAS settings
In this screen you define parameters which are used for NAS discovery:
򐂰 User Name - User name to login to Windows NAS devices
򐂰 Password - Password for Windows NAS devices
Tip: If you use different user names on different NAS devices you can later specify a
different user name and password combination for each device.
򐂰 SNMP Communities - The manager uses SNMP communities to query and identify NAS
filers (for example Network Appliance NAS devices). If you do not specify the community
name, the public community is used.
The NAS discovery process is explained in “NAS discovery” on page 56.
After specifying the required parameters click Next - you will see the Space Requirements
screen as in Figure 4-13.
76
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 4-13 Space requirements
In this screen you can choose the installation path for the Server code. Here you can also see
the required space for the installation, which can help you to select a directory location. If the
destination directory does not exist, you will be prompted for creation of it, after you click
Next. Finally, you will see the installation summary screen in Figure 4-14.
Figure 4-14 Before copying files
At this stage you can still decide to go back and change settings if necessary. Click Next to
start copying files.
If you installed the Tivoli Storage Resource Manager repository in a DB2 UDB database, the
Create Service Account window is shown in Figure 4-15. The Tivoli Storage Resource
Manager creates a new Service account and the Agent will use it when running probes and
scans against DB2 databases on the current machine.

Here you specify the name and location of the database components. Click Next and the
installation process continues as in Figure 4-11 on page 75.
4.3.5 Installing Cloudscape as a test database
This section shows installing using the Cloudscape database as a repository. The
Cloudscape database is recommended for test and demonstration purposes only (not
production) as it is limited on performance. The Cloudscape product provides a complete
Java-based database.
If you select Cloudscape as the database repository when installing, you will see the screen
like Figure 4-20.
Figure 4-20 Cloudscape selection to install
Click Next and the installation process will continue. The pop-up warning in Figure 4-21
advises you not to use the database in a production environment.

Click OK and the installation process continues as from Figure 4-11 on page 75.
4.3.6 Configuration for Web access
The client GUI for management and data collection is automatically installed with the Server
code. With this GUI, you can perform all the Storage Resource Management operations from
the Server system.
You can also access the Server system over the network and perform administration tasks
from a remote workstation. The remote administration console is a Java based applet, which
can be run locally or remotely by downloading it from the Web server.
Remote administration can be done in two ways:
򐂰 Installing the administration GUI on remote workstations as per the instructions in 4.3.7,
“Installation of the GUI code’’ on page 87
򐂰 Setting up the Web access for remote workstations
In our example we set up remote Web access using Microsoft IIS (Internet Information
Server) which is built into Windows 2000. We did the following:
1. Select Start -> Administrative Tools -> Internet Information Services.
2. Right-click Default Web Site and select New -> Virtual Directory (Figure 4-22).

same as in Windows, described in 4.3.3, “Installation of the Server code’’ on page 71.
4.4 Installing the Agent code
This section covers installing the Tivoli Storage Resource Manager Agents.
Windows Agent
To install the Agent code for Windows, run SETUP.EXE from the Windows directory on the Tivoli
Storage Resource Manager CD. The initial screen displays, as in Figure 4-4 on page 71.
Click Next and accept the license. You will see the installation selection screen shown in
Figure 4-35.
Chapter 4. IBM Tivoli Storage Resource Manager installation
89
Figure 4-35 Agent install selection
Select An Agent on this machine and click Next. You will see the Parameters screen, as
shown in Figure 4-36.
Figure 4-36 Agent parameters setup
The Server Port should match the entry from the Server installation - 2078 in our case, as
shown in Figure 4-11 on page 75, or the Agent will not be able to connect to the Server. The
Server Name should be the hostname (or IP address) of the Tivoli Storage Resource Manager
Server. The Agent Port can be any free port on the Agent system. You should use the same
port for all Agents as this helps simplify management.
If you do not want to automatically perform a Scan after the Agent is installed, deselect the
option Agent should perform a SCAN when first brought up (gathers default
statistics).
If for some reason you do not want to allow Agents to accept scripts from the server, deselect
Agent may run scripts sent by server (in addition to local scripts).
90
IBM Tivoli Storage Resource Manager: A Practical Introduction
Tip: You can change how the Agent will handle scripts later by editing the config file and
restarting the Agent.
After supplying all the parameters click Next. The installation program will check the
connection to the Server. The Space Requirements screen will display, as shown in
Figure 4-37.
Figure 4-37 Space requirements
Here you can see the required space for installation and specify the installation directory. If
the directory does not exists you need to confirm its creation. Click Next, then confirm the
settings on the next screen. Select Next to start copying files. After the installation is
complete, the Agent will automatically start.
If you are installing on an Agent with a NetWare client, you will be prompted to create a local
account for the Agent (as shown in Figure 4-38) before the Agent is started after installation.
Figure 4-38 Novell logon ID creation
This account can only be created if you are logged into the Novell NDS with sufficient
privilege.
UNIX Agent
Install the UNIX Agent by running ./setup.sh from the appropriate directory. Our example is
a Linux Agent. If you execute the script without parameters, the help is displayed as shown in
Example 4-1.
Chapter 4. IBM Tivoli Storage Resource Manager installation
91
Example 4-1 Running UNIX Agent installation script
Linux-1:/tmp/SRM/linux # ./setup.sh
To run the GUI install:
setup.sh -g
To run a quick (agent-only) install:
setup.sh -s <server-host> [-d <dest-dir>] [-p <server-port>]
[-q <agent-port>] [-x] [-n] [-l [o][r]]
<dest-dir>
defaults to /usr/Tivoli/TSRM or /opt/Tivoli/TSRM
<server-port> defaults to 2078
<agent-port> defaults to 2077
-x prevents agent from running scripts sent from server
-n prevents agent from running initial scan
-l identifies the products that will be licensed on this agent
Valid product codes are: o - Tivoli SRM
r - Tivoli SRM for Databases
Linux-1:/tmp/SRM/linux # ./setup.sh -s bonnie -d /opt/tivoli/TSRM -p 2078 -q 2077 -l o
There are two ways to install a UNIX Agent:
򐂰 Graphical - using ./setup.sh -g The installation procedure is the same as for the
Windows Agent, shown in “Windows Agent” on page 89.
򐂰 Text (quick) mode - using ./setup.sh and specifying parameters on the command line
To install the Agent using the quick method, you need to supply the following parameters:
򐂰 -s servername - The Server name or IP address
򐂰 -d directory - The installation directory. The usual installation places are in /opt and /usr.
Specify the full path, for example /opt/tivoli/ITSRM.
򐂰 -p serverport - The Server port
򐂰 -q agentport - The Agent port
Note: The d, p, and q parameters can be omitted, if so, these defaults will be used:
򐂰 d - /opt/tivoli/TSRM or /usr/tivoli/TSRM, depending on the platform
򐂰 p - 2078
򐂰 q - 2077
򐂰 -l products - The products which you want to be active on this Agent:
–
–
–
–
o - Base component
r - Oracle Agent
m - Microsoft SQL-Server Agent
s - Sybase Agent
In our example we executed the following command:
./setup.sh -s bonnie -d /opt/tivoli/TSRM -p 2078 -q 2077 -l
During installation you will see messages similar to those shown in Example 4-2.

For a Linux Agent, the installation process will create an auto-start entry in /etc/init.d and link
to this entry in runlevel 3 and 5. Other UNIX variants will create a similar entry in the
appropriate file to enable automatic start of the Agent on system start.
If for some reason, the Agent no longer appears in the Agent list, or it is marked as
Unreachable, and the network connection is working, you can force the registration process
by creating an empty file called PROBE_ME in the Agent installation directory. For example, on
Windows use C:\Program Files\Tivoli\TSRM\PROBE_ME. If the Agent showed as
Unreachable, you should first delete it from the Agent list.
Note: If you delete or reregister an Agent you will lose all historical data for this Agent.
4.5 Applying maintenance to Tivoli Storage Resource Manager
In the current release of the product, you apply maintenance by running the installation
program. Follow these steps to apply maintenance:
1. On the welcome screen (Figure 4-39) select Apply maintenance to IBM Tivoli SRM.
Chapter 4. IBM Tivoli Storage Resource Manager installation
93
Figure 4-39 Selecting to apply the maintenance
2. Click Next, you will see the maintenance selection screen similar to Figure 4-40.
Figure 4-40 Product maintenance selection
3. In this case, we are upgrading the Server. Select The IBM Tivoli SRM Server and all of
its Agents and click Next.
If the Server being upgraded uses IBM DB2 as the repository database, you will see the
screen shown in Figure 4-41; otherwise, you will go directly to the confirmation screen in
the next step.
94
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 4-41 DB2 admin user ID and password
4. Here you have to enter the DB2 administrator user ID and password. Click Next and you
will see the confirmation screen. Click Next to start the maintenance.
5. After all the upgraded files are copied, the summary screen (Figure 4-42) displays.
Figure 4-42 Maintenance finished
Check for errors and click Done to finish the maintenance process.
After performing maintenance on the Server system, the Server will automatically upgrade all
the Agents.
If for any reason you need to force an upgrade of the Agents with the same version currently
available, you need to create an empty file with the name UPGRADE_AGENTS in the Server
installation directory. For example, in Windows C:\Program Files\Tivoli\TRSM This will force
an upgrade.
Chapter 4. IBM Tivoli Storage Resource Manager installation
95
Maintenance can also be performed separately for the Agent and GUI installation by selecting
the other options on Figure 4-40.
4.5.1 Planned upgrade installation for Agents
IBM Tivoli Storage Resource Manager Version 1.2 can now update agents connected to the
Server. You can define a job for these actions, as shown in Figure 4-43. We selected the
Agent on BANDA to upgrade by highlighting it and clicking the circled arrow button.
Figure 4-43 Select Agent to upgrade
You can also choose a time to perform the upgrade (When to Upgrade tab in Figure 4-44). We
chose to perform the upgrade immediately.
96
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 4-44 Schedule agent upgrade
Under Options, (Figure 4-45) you can force a reinstall if the Agent is already on this level.
Figure 4-45 Force upgrade on Agent
Chapter 4. IBM Tivoli Storage Resource Manager installation
97
On the Alert tab, you can define actions in the event of an error. We selected to send an event
to the TEC console by checking TEC Event.
Figure 4-46 Alert selection for failed Agent upgrade.
After saving the job, the scheduler will run it at the selected time (immediately in this case).
Each Agent will be stopped, upgraded, and restarted.
4.6 Basic administrative tasks
This section describes some basic administrative tasks for Tivoli Storage Resource Manager.
4.6.1 Security
To log in to the Tivoli Storage Resource Manager Server, you can use any local user ID on the
Server system. During installation you can specify the administration group (shown in
Figure 4-11 on page 75). The members of this group will be able to perform all tasks using the
GUI interface. We recommend creating a special group for Tivoli Storage Resource Manager
administrators. The group name can be changed after installation by editing the server.config
in the config directory and restarting the Server services. An example of the file is shown in
Example 4-3.
Example 4-3 Tivoli Storage Resource Manager server.config file
[controller]

Log-File Retention
This option defines how long to keep the log files, as shown in Figure 4-68.
Figure 4-68 Log File Retention
The possible parameters are:
򐂰 Keep at most n runs of each schedule - The numbers of runs you want to keep for each
scheduled job.
򐂰 Keep at most n day’s worth of log-files, regardless of schedule - The number of days
you want to keep the log files. Every log file older that this will be deleted.
򐂰 Quota Email Address Rules - Here you specify the rules for generating the e-mail
address of Quota violators based on login name, first name, and/or last name as they are
registered within the OS. The Quota Email Address Rules screen is shown in Figure 4-69.
Chapter 4. IBM Tivoli Storage Resource Manager installation
115
Figure 4-69 Filters for Quota Email
Depending on the OS, Tivoli Storage Resource Manager obtains the user names from:
򐂰
򐂰
򐂰
򐂰
Windows 2000 - Full name field, from LDAP
Windows NT - Full name field, from domain-level security database
NetWare - Surname and Given name fields, from LDAP
UNIX - User description from the password file
The name is stored in the repository database and then specific algorithms are used to
extract the names for building e-mail address rules. In the example shown in Figure 4-69, the
last name plus the first character of the first name will be used to create the name. When
e-mail is sent the default domain defined in Alert Disposition (see “Alert Disposition” on
page 114) will be appended.
More explanation on setting up the rules is in the manual IBM Tivoli Storage Resource
Manager Configuration and Getting Started Guide, SC32-9067.
Scan/Probe Agent Administration
Here you assign the Agents which will perform scanning and probing of NAS filesystems and
the volumes and filesystems of an NDS tree. The Scan/Probe Agent Administration screen is
shown in Figure 4-70.
116
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 4-70 Agent selection for NAS and NDS
The following information is displayed:
򐂰 Licensed NetWare servers
򐂰 NetWare volumes discovered by discovery jobs
򐂰 Discovered NAS filesystems
This information is gathered during the discovery process on the Agents accessing NAS
devices and Novell NetWare servers.
The Agent systems with access to the NAS or NetWare volumes and filesystems will be
displayed here along with information on which volume or filesystem(s) they are using.
Important: If the discovery jobs are not run against NDS trees and NAS devices, the
volumes and filesystems will not be displayed.
To change the Agent that will scan the volume and filesystem, select the desired row(s) and

4.7 Microsoft Cluster installation
In this section we will outline how to install Tivoli Storage Resource Manager in a Microsoft
Cluster (MSCS) environment using IBM DB2 as a local repository for the database. We will
provide step by step instructions to:
򐂰 Install and configure Microsoft Cluster server on clustered systems
򐂰 Install and configure DB2 on clustered systems
򐂰 Install and configure the Tivoli Storage Resource Manager Server on clustered systems
Our environment uses the following setup:
򐂰 Two Windows 2000 Advanced servers with Fix Pack 2 installed, members of the same
domain. The primary system is DIOMEDE, with SENEGAL as the other cluster member.
Important: The clustered systems must be members of the same domain. They can
also be domain controllers.
򐂰 One Fibre Channel HBA in each of the systems attached to the SAN
򐂰 IBM FAStT Storage system with two 10GB LUNs FC-attached to the hosts. The LUNs
were configured to be seen by both systems. The first LUN was used as the quorum disk
and the second LUN was used as the data disk for DB2 and Tivoli Storage Resource
Manager.

4.7.1 Microsoft Cluster initial setup
We followed these steps to implement the Tivoli Storage Resource Manager cluster:
1. Install Windows 2000 Advanced server on both systems.
2. Prepare two shared LUNs on storage accessible from both systems.
3. Check both systems can see the disks. Make sure that the disks are Basic type.
4. Create the partitions, format the disks using NTFS filesystem, and assign drive letters to
both disks. In our example the first disk was E: and the second disk was F:.
5. Check that the disks are visible from the second system with the same drive letters. If the
disks cannot be seen, restart the system.
6. Each system requires two network adapters. We recommend that one from each system
is connected through a dedicated link, for example, with an Ethernet crossover cable.
These adapters will be used for the heartbeat. Both adapters must use static IP
addresses.
Tip: We recommend using private subnet addresses for the heartbeat adapters.
7. Obtain two additional IP addresses, to be used for the cluster setup.
124
IBM Tivoli Storage Resource Manager: A Practical Introduction
8. Start the cluster installation and configuration on the first node, in our example DIOMEDE,
by accessing Add/Remove Windows Components in Control Panel -> Add/Remove
Programs. Select Cluster Service and click Next. Figure 4-81 displays the Configuration
Wizard.

128
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 4-89 Private network
17.In this panel you select roles for each network defined on the systems. At least two
networks are required, they can have the following roles:
– Client access - The network will be used for client access.
– Internal cluster communication only - The network will be used for cluster heartbeat.
– All communications - The network will be used for both communication methods
mentioned above.
In our example we selected our Local Area Connection network for Internal cluster
communication only.
Figure 4-90 shows our second Network configuration.
Figure 4-90 Public network
Chapter 4. IBM Tivoli Storage Resource Manager installation
129
18.In this window we selected to use Local Area Connection 2 for All communications
Tip: We recommend defining the All communications mode for the second adapter if
you have only two network adapters in the system.
After completing the network connection setup, click Next to continue to the Internal
Cluster Communication screen shown in Figure 4-91.
Figure 4-91 Network priority for internal cluster communication
19.If more than one network was defined for cluster communication, the priority order for
them must be specified. In our example, we specified one network for private
communication and another network for all communications, therefore, we will define the
private network as the top priority network used for inter-cluster communication. If this
network fails, the all communications network will be used for inter-cluster communication
as well as client access.
The Cluster IP address screen comes next, shown in Figure 4-92.
130
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 4-92 Cluster IP address
20.Here you define the Cluster IP Address to be used by clients to access cluster resources.
If additional networks were defined for public or all communications access, you need to
also specify the network to which this address will be bound. In our example we used the
Local Area Connection 2 network.
After defining the address click Next to continue, and Finish to end the installation and
configuration on the first node.
21.Start the cluster installation and configuration on the second node, (SENEGAL in our
example) by accessing Add/Remove Windows Components in Control Panel ->
Add/Remove Programs, and selecting Cluster Service. The first windows shown are
identical to those for the primary cluster node (Figure 4-81 on page 125, and Figure 4-82
on page 125). Continue to the Create or Join a Cluster screen, shown in Figure 4-93.

22.As we are joining the existing cluster, select The second or next node in the cluster.
Next, specify the cluster name (Figure 4-94).
Figure 4-94 Joining cluster name
23.Enter the name of the cluster you created on the first node (in step 12 on page 126) and
supply the same user ID, password, and domain of the account you will use to connect to
the cluster (in step 13 on page 127). Click Next. Figure 4-95 displays.
Figure 4-95 Account for running the service
24.Specify the password for the domain account which will be used to run the cluster service
on this node. Click Next and then Finish to complete the installation and configuration of
the cluster.
132
IBM Tivoli Storage Resource Manager: A Practical Introduction
25.Check if the cluster service is running by starting Cluster administration from
Administrative Tools. If the cluster is running all the nodes (DIOMEDE and SENEGAL in
our example) should be up and all resources should be online as shown in Figure 4-96.
Figure 4-96 Running cluster
Tip: If you installed the cluster from media at a lower Service Pack level than the installed
one, you should reapply the latest Service Pack on both nodes before continuing.
4.7.2 Adding shared disk resource for DB2 instance and SRM installation
In our setup, we use a local DB2 database for the Tivoli Storage Resource Manager
repository. To enable this for clustering, we need to provide a clustered instance for this
database, which requires definition of an additional shared disk resource. We have already
defined Disk F: to our cluster as shown in Figure 4-96 on page 133, as a member of the
Cluster group, but it will be later moved to a new cluster group used for the Tivoli Storage
Resource Manager Server cluster.
4.7.3 Installation of DB2 database on both nodes
To cluster the DB2 instance we need to install DB2 on both nodes. The application should be
installed on a local drive, in our example drive C:.
Before installing, create a user ID that will be used to install DB2 (db2admin in our example).
This user ID should be a member of the Windows DomainAdmins group. To start the
installation, log on using this newly created user ID.
When installing DB2, you only need to select the DB2 Enterprise Edition component. You
can then accept all defaults - the only thing you need to change is to select Do not install the
OLAP Starter Kit. After installation, restart the system and apply the appropriate Fix Pack.
In our installation we used IBM DB2 Enterprise Edition 7.2 with Fix Pack 7.
4.7.4 Setting up a clustered instance in DB2
To have a clustered database we need to create a clustered instance. The DB2 installation
provides the db2mscs utility, which automatically changes the existing instance to a clustered
Chapter 4. IBM Tivoli Storage Resource Manager installation
133
instance, and also creates a new cluster group and all needed resources. Follow these steps
to create the clustered instance:
1. Log on to the system which currently owns the shared disk for the DB2 instance, in our
example Disk F:, with the user ID you created for DB2 installation.
2. Create a new instance, in our example ITSRM, using the following command:
db2icrt ITSRM
3. In the DB2 installation directory create a file DB2MSCS.CFG file with the following entries:
– DB2_INSTANCE - The instance to be clustered
– CLUSTER_NAME - The cluster in which this instance will be clustered
– GROUP_NAME - The cluster group for this instance. We recommend not using the
default Cluster Group here.
– IP_NAME - The IP address to be used for accessing this instance
– IP_ADDRESS - The fixed IP address to be used for accessing this instance
– IP_SUBNET - The subnet mask for IP_ADDRESS
– IP_NETWORK - The network to be used for accessing the instance. Usually this is
either the public or all communications network.
– NETNAME_NAME - The network name to be used to access this instance
– NETNAME_VALUE - The value for the network name to be used for accessing the
instance.
– NETNAME_DEPENDENCY - The IP address on which the network name will need to
be available before. In our case this should be the IP address defined in this
configuration file.
– DISK_NAME - The shared disk to be used for this instance. This resource must exist,
and should not be the quorum disk. The instance directory will be copied to this
resource.
– INSTPROF_DISK - If you specified more then one DISK_NAME, which will be moved
into the instance cluster group, you can specify which disk will be used for the instance
specified in the DB2_INSTANCE parameter.
You can see the configuration file we created in Example 4-4.
Example 4-4 DB2MSCS.CFG file for ITSRM instance
DB2_INSTANCE=ITSRM
CLUSTER_NAME=ITSOSRMCL
GROUP_NAME=SRMCluster
IP_NAME=SRMCluster IP Address
IP_ADDRESS=9.1.38.73
IP_SUBNET=255.255.254.0
IP_NETWORK=Local Area Connection 2
NETNAME_NAME=SRMCluster Network Name
NETNAME_VALUE=CLUSTER2
NETNAME_DEPENDENCY=SRMCluster IP Address
DISK_NAME=Disk F:
INSTPROF_DISK=Disk F:
4. Run the following command to cluster the instance you created in step 2:
db2mscs -f:DB2MSCS.CFG
The command will define all the necessary cluster objects and copy the database instance
files to the clustered disk.
134
IBM Tivoli Storage Resource Manager: A Practical Introduction
5. After the command successfully finishes, the new cluster group with the name defined in
the configuration file will appear in the cluster definition, as seen in Figure 4-97.
Figure 4-97 DB2 clustered instance
6. Verify that all resources in the new cluster group, in our example SRMCluster, are online.
You can verify the database instance by accessing it in the DB2 Control Center and
creating a sample database. You can also try to failover the resource group and see if the
instance is available.
When you have verified that the clustered instance is working and is capable of failover,
continue with the next installation steps.
4.7.5 Installing IBM Tivoli Storage Resource Manager Server on both nodes
In our example we installed the Tivoli Storage Resource Manager Server on the same disk as
the DB2 clustered instance, Disk F:.
Follow these steps to install Tivoli Storage Resource Manager Server on both nodes:
1. Log on to the first node (DIOMEDE) as the Domain Administrator.
2. If required, fail over the DB2 instance cluster group, in our example SRMCluster, to the
first node in the cluster. This is necessary for our configuration as the DB2 instance is
installed on Disk F: in this group and this disk is required to install the Tivoli Storage
Resource Manager Server on it.
3. Create the database in a non-clustered local instance. We created ITSRMDBD in the DB2
instance as shown in Figure 4-98.
Chapter 4. IBM Tivoli Storage Resource Manager installation
135
Figure 4-98 Database on first node
4. Install Tivoli Storage Resource Manager Server following the instructions in 4.3.3,
“Installation of the Server code’’ on page 71, using the database created in step 3 as the
repository, in our example ITSRMDBD. Use the cluster NETNAME_VALUE, in our
example cluster2, for the server name (Example 4-4 on page 134). We installed in the
directory F:\Tivoli\TSRM.
5. After installation, stop the services for Server and Agent, and change them to manual
startup mode as shown in Figure 4-99.
Figure 4-99 Service mode
6. Rename the installation directory. In our example we renamed it to F:\Tivoli\TSRMD.
136
IBM Tivoli Storage Resource Manager: A Practical Introduction
7. During the installation, the TSRMsrv1 Domain account is created. This account has to be
deleted before installing on the second node.
8. Failover the DB2 instance cluster group, in our example SRMCluster, to the second node
in the cluster. This is necessary as we will install Tivoli Storage Resource Manager on this
drive.
9. Log on to the second node as the Domain Administrator.
10.Create the database in a non clustered local instance. In our example we created
ITSRMDBS in the DB2 instance as shown in Figure 4-100.
Figure 4-100 Database on second node
11.Install Tivoli Storage Resource Manager Server following the instructions in 4.3.3,
“Installation of the Server code’’ on page 71, using the database created in step 10 as the
repository, in our example ITSRMDBS. Use the cluster NETNAME_VALUE, in our
example cluster2, for server name. In our example we installed in the directory
F:\Tivoli\TSRM.
12.After installation, stop the services for Server and Agent, and change them to manual
startup mode as shown in Figure 4-99.
4.7.6 Copying the repository database to the clustered instance
To copy the database from the local instance to the clustered instance, do the following on the
second node with the clustered instance cluster group, (SRMCluster), active on this node:
1. Define the clustered instance, in our example ITSRM, in DB2 Control Center as shown in
Figure 4-100.
2. Make a backup of the local database used for the Tivoli Storage Resource Manager
Server, in our example ITSRMDBS, using the database backup tool from DB2 Control
Center.
3. Restore the database into the clustered instance using a different name; in our example
we used SRMDBCL, using the database restore tool from DB2 Control Center.
4. Failover the clustered instance to the first node.
Chapter 4. IBM Tivoli Storage Resource Manager installation
137
5. Define the clustered instance, in our example ITSRM, in DB2 Control Center as shown in
Figure 4-98 on page 136.
6. Define the restored database, in our example SRMDBCL, in DB2 Control Center as shown
in Figure 4-98 on page 136. Check if the database can be accessed normally.
Continue with the setup when you have verified that the database in the clustered instance
can be accessed from both cluster nodes.
4.7.7 Editing the Server config file to reflect the database change
As we will be using a database in a clustered instance, the Tivoli Storage Resource Manager
Server configuration file (server.config in the config directory) needs to be changed to point to
this database. Example 4-5 shows the config file we used.
Example 4-5 Server config file
[controller]
name="cluster2"
port=2078
maxConnections=500
routerThreads=1
serviceThreads=2
agentErrorLimit=3
adminGroup="Administrators"
commEncrypted=0
[logging]
logsKept=5
messagesPerLog=100000
[repository]
driver=COM.ibm.db2.jdbc.app.DB2Driver
url="jdbc:db2:SRMDBCL"
user=TivoliSRM
connectionPool=10
[service]
name=TStorm.server.svp.GuiSvp
[service]
name=TStorm.server.svp.AgentSvp
[service]
name=scheduler.Scheduler
As you can see we changed the database URL to url=”jdbc:db2:SRMDBCL” to reflect that the
repository database was moved to the clustered instance.
4.7.8 Creating clustered resources for the Server and Agent
Now we are ready to set up the Tivoli Storage Resource Manager Server and Agent as
clustered resources so they will be able to failover.
Follow these steps to define the resources for operating in a clustered environment:
1. Change the password of the TSRMsrv1 domain account to a new value. The password is
randomly generated by the initial install program, and it is used to run the Tivoli Storage
Resource Manager service. Since we need to synchronize this password on both systems,
we must manually reset it.
2. Edit the logon properties for the Tivoli Storage Resource Manager Server service on both
cluster nodes to reflect the password changes. Right-click on the service entry in the
138
IBM Tivoli Storage Resource Manager: A Practical Introduction
Services applet and select Properties. You should see the window as shown in
Figure 4-101.
Figure 4-101 Password change
Select the Log On tab and enter the new password.
Attention: If you do not change the password on both nodes, the service will fail to
start.
3. Using Cluster Administration, define a new Generic Service resource for the Tivoli
Storage Resource Manager Server in the clustered instance group, in our example
SRMCluster group. When creating the resource you should define it to be dependent on
the following resources:
–
–
–
–
The disk where you installed the Server
The clustered database instance
The clustered IP address
The clustered Network Name
You can see these values in our example in Figure 4-102.
Chapter 4. IBM Tivoli Storage Resource Manager installation
139
Figure 4-102 Resource dependences
The service name used for this resource is TrelliSrv1 as shown in Figure 4-103.
Figure 4-103 Server service name
Also check Use Network Name for computer name, so that the Network Name defined
for this cluster group will be associated with this resource.
4. Using Cluster Administration define a new Generic Service resource for the Tivoli
Storage Resource Manager Agent in the clustered instance group, in our example
SRMCluster group. When creating the resource you should define it to be dependent on
the following resources:
–
–
–
–
The disk where you installed the Server
The clustered database instance
The clustered IP address
The clustered Network Name
You can see these values in our example in Figure 4-102.
140
IBM Tivoli Storage Resource Manager: A Practical Introduction
The service name used for this resource is TrelliSrv1 as shown in Figure 4-104.
Figure 4-104 Agent service name
5. After creating both resources, bring them online, as in Figure 4-105.
Figure 4-105 Cluster view
If all resources are online your Tivoli Storage Resource Manager Server cluster
implementation is ready to use.
Note: When installing the Agents point them to the name which resolves into the cluster IP
address, in our example SRMCluster IP Address as shown in Figure 4-105.
Chapter 4. IBM Tivoli Storage Resource Manager installation
141
4.8 Manager HA install using remote Oracle database
This section shows how to install Tivoli Storage Resource Manager using a remote Oracle
database. Enterprise database servers are usually already clustered for HA (high availability),
so we will not discuss that further here. We will only focus on protecting the application server
itself. We will set up a primary Tivoli Storage Resource Manager Server using a remote
Oracle database. We will then have a standby Server which can be manually switched over in
the event of failure of the primary. Note this scenario does not use automatic failover.
For this installation we used Oracle 8.1.7 running on a Windows 2000 server as the
repository. Before installing, you need to install a JDBC driver for the database. This driver
can be downloaded from the following Web site:
http://otn.oracle.com/software/tech/java/sqlj_jdbc/content.html
or located in the Oracle installation directory:
[install drive]:\Oracle\Ora81\jdbc\lib
Put the JDBC drivers on the local drive of the systems where the Tivoli Storage Resource
Manager Server will be installed.
Our configuration will use the environment shown in Figure 3-11 on page 61. To set this up:
1. Create the repository database on the Oracle database server.
Our database server was installed in the system GALLIUM, and created using the Oracle
Database Configuration Assistant (Figure 4-106).
Figure 4-106 Starting Oracle Database Configuration Assistant
2. Select Create a database and click Next. On the next screen select Typical and click
Next. Select Create new database files and click Next. For the primary type of database
usage, select Multipurpose and click Next. You can accept the default value for
Concurrently connected users, (in our example, 15) and click Next. On the screen
where you can select options to use with the database, you should deselect all options
and then click Next. A screen similar to Figure 4-107 will display.
142
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 4-107 Selecting the database name
3. Here you define the database name, in our example ITSRMREM. The Assistant will
automatically define the SID for the database, and in our example we accepted the default
value ITSRMREM. After specifying the name click Next. In the next window, select No
don’t register the database and click Next. In the window asking when to create the
database select Create Database Now and click Finish. The assistant will create the
database.
4. Install the Tivoli Storage Resource Manager Server on the standby server using this
database, following the instructions in 4.3.3, “Installation of the Server code’’ on page 71.
In the step for database selection, choose Oracle. The screen shown in Figure 4-108
displays.

7. Stop the Tivoli Storage Resource Manager Server service and set the startup type to
manual, using the Services applet under Administrative tools (Figure 4-110).
Figure 4-110 Setting services to manual
8. Clear the repository database, using the Oracle database tools. Delete and recreate the
database with the same name as when you created it (ITSRMREM in our example). This
is required because the installation program tries to create the repository in the database
and if the repository already exists, the installation will fail.

IBM Tivoli Storage Resource Manager: A Practical Introduction
9. Install the Tivoli Storage Resource Manager Server on the primary server using the same
parameters as on the standby server.
Note: If you are using this scenario for HA, you need to maintain two directories inside
the Tivoli Storage Resource Manager installation directory in a consistent state. These
directories are:
򐂰 config - for the configuration files. After installation or changes on the primary server,
you need to copy those two files to the standby server:
– repository
– nas.config
򐂰 scripts - for scripts. If you use server distribution to the Agents for the scripts, all
scripts must be copied on both servers.
4.8.1 Testing the standby HA installation
To test the scenario, we simulated a primary server failure. We then did the following:
򐂰 In the DNS server we changed the settings so that the name of the primary server pointed
to the standby server IP address.
򐂰 Started the Tivoli Storage Resource Manager Server services on the standby server.
After starting the services, the standby server connects to the remote database repository
using the same settings as the primary server. As all the information except scripts and basic
configuration options are in the database, the operations can resume.
Tip: For the best results you should keep the clocks of the primary and standby servers
synchronized.
Note: The local Agent installed on the primary server will not appear. Also, all tasks related
to that Agent will fail as the name of the standby server Agent is not the same as for the
primary server.
4.9 CIM/OM
This section describes how CIM/OM works, how to install and configure the CIM/ON server,
and how to configure Tivoli Storage Resource Manager to login into the CIM/OM server.
4.9.1 What is CIM/OM?
The Common Information Model (CIM) agent consists of the CIM Object Manager (CIM/OM),
the Service Location Protocol (SLP), and the device provider. A device can be a storage
server such as an IBM TotalStorage Enterprise Storage Server (ESS). The CIM agent
registers itself with SLP to enable discovery by the Client application. The SLP is a directory
service called by a client application to locate the CIM Object Manager. The client application
and the CIM/OM communicate through CIM Messages. The CIM/OM and device provider
communicate through method calls made from the CIM/OM to the provider. The device
provider communicates with the device through proprietary calls. Figure 4-111 shows the
ESS CIM/OM implementation.

IBM Tivoli Storage Resource Manager supports reporting from CIM compliant devices. At the
present time, the only tested device is the ESS using its CIM/OM server. IBM Tivoli Storage
Resource Manager gathers and reports on ESS devices defined in the CIM/OM server. It
uses Probe jobs to collect information about the defined ESS devices and uses the reporting
facilities to view that information.
4.9.2 CIM/OM Server installation for ESS
The supported platforms for the CIM/OM server are shown in Figure 4-112.

Figure 4-112 CIM/OM server supported platforms
To install and configure the ESS CIM/OM server you need:
򐂰 ESS 2.1.1.135 or later for model F20 and 2.1.1.136 or later for model 800
򐂰 Command line Interface (CLI) Version 2.1.1.8 or later
򐂰 TCP/IP communication
In our example we installed the CIM/OM server V1.1.0.1 on Windows 2000 Advanced Server.
The CIM/OM software can be downloaded from the Web site:
http://www-1.ibm.com/support/search.wss?rs=586&q=ssg1*&tc=STHUUM&dc=D400
Pre-installation task
Before installing the CIM/OM server, the ESS CLI has to be installed and configured correctly.
In our example we used ESS CLI Version 2.1.1.8. Verify the ESS CLI is correctly installed
using the command shown in Example 4-6.
Example 4-6 Checking ESS CLI installation

Chapter 4. IBM Tivoli Storage Resource Manager installation
149
Post-installation
The installation process creates two system services:
򐂰 Service Location Protocol (SLP)
򐂰 IBM CIM Object Manager
After installation, verify the two services are running, as they are essential to provide the
CIM/OM interface to the managed ESS devices.
CIM/OM configuration
Now you need to configure the CIM/OM to actually access the ESS and start providing this
information to the CIM enabled management application.
1. Define the users who will access the CIM/OM interface to gather data. Open a command
prompt with Start -> Programs -> IBM TotalStorage CIM Agent for ESS -> Configure
CIMOM Users. Use the adduser command as in Example 4-7.
Example 4-7 Adding CIM/OM users
Application setuser started in interactive mode
To terminate the application enter: exit
To get a help message enter: help
>>> adduser itsrm itsrm
An entry for user itsrm successfully added
>>>
In our example we defined user itsrm, with password itsrm. The exit command closes
the window.
2. Define the ESSs which will be controlled by the CIM/OM server. Open a command prompt
with Start -> Programs -> IBM TotalStorage CIM Agent for ESS -> Enable ESS
Communication. Use the address command (Example 4-8) to define a managed ESS.
Example 4-8 Defining ESSes to be managed by CIM/OM
Application setdevice started in interactive mode
To terminate the application enter: exit
To get a help message enter: help
>>> address 172.31.1.1 storwatch specialist
An ess provider entry for IP 172.31.1.1 successfully added
>>>
3. After applying these definitions, we recommend rebooting the CIM/OM server.
4. To check that the setup is correct, run the verifyconfig command in the CIM/OM
installation directory as shown in Example 4-9.
Example 4-9 Verifying ESS CIM/OM configuration

IBM Tivoli Storage Resource Manager: A Practical Introduction
Your Managed Systems should be listed as IBMTSESS_StorageSystem. If not, re-check
all the setup steps.
Tip: If the verification still fails, try restarting both the CIM/OM services before re-verifying.
Upgrading CIM/OM
At the time of writing there was a fix Version 1.1.0.2 available for CIM/OM. It is recommended
to install this fix, which can be downloaded from:
http://www-1.ibm.com/support/search.wss?rs=586&q=ssg1*&tc=STHUUM&dc=D400
To install the update, do the following:
1. Stop the CIM/OM related services:
– Service Location Protocol (SLP)
– IBM CIM Object Manager
2. Unpack the fix file to a temporary directory, and run the cimagentfix.cmd to start the
update. You will see a screen similar to Figure 4-116.
Figure 4-116 Welcome screen
3. Click Next to start the installation; it will check the current and new version, as shown in
Figure 4-117.
Chapter 4. IBM Tivoli Storage Resource Manager installation

152
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 4-119 Installation finished
6. Click Finish to end the installation process.
After the upgrade, check if the CIM/OM related services are running, and verify the
configuration as shown in Example 4-9 on page 150.
CIM/OM security
By default CIM/OM server uses secure communication with certificates. The certificate
created during installation is in the file truststore in the installation directory. You can create
new certificates with the command mkcertificate The new certificate will also be stored in
the truststore file.
IBM Tivoli Storage Resource Manager supports secure communication with CIM/OM. If you
are using an application which does not support the secure protocol, the CIM/OM server can
be configured to run in insecure mode. Follow the instructions in Common Information Model
Agent Installation and Configuration Guide for the IBM Enterprise Storage Server,
GC35-0485.
Your CIM/OM server for IBM ESS is now ready to do some serious reporting.
4.9.3 CIM/OM configuration in IBM Tivoli Storage Resource Manager
Before using the storage subsystem reports with IBM Tivoli Storage Resource Manager, you
need to register the CIM/OM server as follows:
1. Navigate to CIM/OM Logins node in the navigation tree as shown in Figure 4-120.
Chapter 4. IBM Tivoli Storage Resource Manager installation
153
Figure 4-120 CIM/OM Logins in navigation tree
2. To create a new CIM/OM login definition, click Create. Figure 4-121 displays.
Figure 4-121 Defining CIM/OM login
The following fields have to be populated:
– Host Name - fully resolvable name of the CIM/OM server - in our example w2kadvtsm.
– Port - the CIM/OM CP/IP port. The CIM/OM server for ESS uses port 5989 for secure
communication port and 5988 for insecure communication. In our example we used
port 5989.
154
IBM Tivoli Storage Resource Manager: A Practical Introduction
– Protocol - The ESS CIM/OM server can use either https or http for the protocol. In our
example we used the secure protocol https.
– User Name - the user name which is defined in the CIM/OM server. In our example we
used itsrm (step 1 on page 150).
– Password - the corresponding password for the user name.
– Certificate File - the certificate file which was created on the CIM/OM server.
Tip: The truststore file has to be copied from the CIM/OM server to the machine
where IBM Tivoli Storage Resource Manager server is installed. If both are running
on the same machine, you can use the original location.
After entering all the required data, click Save to store the information into the repository
database. The defined CIM/OM login will appear similar to Figure 4-120.
Once you have defined the CIM/OM login(s) you can edit or delete them using the Edit
and Delete buttons.
3. Before you can start collecting data for CIM/OM managed ESSs, you need to discover
them. The discovery is done using the CIM/OM login information by the Agent on the IBM
Tivoli Storage Resource Manager Server. Select Discovery under Monitoring in the IBM
Tivoli SRM Tree. Right-click the Discovery tree and select Run Now as shown in
Figure 4-122.
Figure 4-122 Running discovery
4. Once discovery is complete, you should see two entries from the Agent installed on the
IBM Tivoli Storage Resource Manager Server. If you scroll the status window correctly you
can distinguish which was the CIM/OM discovery as shown in Figure 4-123.
Chapter 4. IBM Tivoli Storage Resource Manager installation
155
Figure 4-123 Finding CIM/OM discovery
The Log File Name for the CIM/OM will include cimom_discovery in the name, thus
identifying it as the discovered CIM/OM. To see if the discovery was successful, display
the job output information by double clicking the spy glass symbol circled in Figure 4-123.
The output is shown in Figure 4-124.
156
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 4-124 Discovery job output
Our output shows that the ESS subsystem (2105.18921, where 18921 is the ESS serial
number) was discovered and configured. You can also see that CIM/OM data was queried
from the host w2kadvtsm which is the CIM/OM server.
5. Once the ESS is discovered, it can be configured for monitoring. Navigate to CIM/OM
Storage Subsystem Administration in the Navigation Tree as shown in Figure 4-125.
Figure 4-125 Storage Subsystem Administration
All discovered ESS’s will be displayed. To enable reporting on particular ESS, check the
Monitored square as shown in Figure 4-125.
Chapter 4. IBM Tivoli Storage Resource Manager installation
157
You can also set an alias, which will be then used in reports, by selecting the ESS entry
and clicking on Set disk alias. In our example we specified ESSF20 as an alias.
We give details of ESS subsystem reporting in 6.3, “Tivoli Storage Resource Manager

Figure 5-1 Tivoli Storage Resource Manager Monitoring features
The Monitoring features of Tivoli Storage Resource Manager enable you to run regularly
scheduled or on-the-flight data collection jobs. These jobs gather statistics about the storage
assets and their availability and their usage within your enterprise, and make the collected
data available for reporting.
We will now give a quick overview of the monitoring jobs, and explain how they work through
practical examples.
Reporting on the collected data is explained in Chapter 6, “Reporting” on page 247.
5.1.1 Navigation tree
Figure 5-2 shows the complete navigation tree for OS Monitoring which includes Groups,
Discovery, Pings, Probes, Scans, and Profiles.

Figure 5-2 OS Monitoring tree
Except for Discovery, you can create multiple definitions for each of those monitoring features
of Tivoli Storage Resource Manager. To create a new definition, right-click on the feature and
select New <feature>. Figure 5-3 shows how to create a new Scan job.
Figure 5-3 New Scan job creation
Once saved, any definition within Tivoli Storage Resource Manager can be updated by
right-clicking on the object and selecting Edit. This will put you in Edit mode. Save your
changes by clicking the floppy disk icon in the top menu bar.
Chapter 5. Operations: Policy, Quotas, and Alerts
161
Discovery, Pings, Probes, and Scan menus contain jobs that can run on a scheduled basis or
ad hoc. To execute a job immediately, right-click the job then select Run now (see
Figure 5-4). Each execution of a job creates a time-stamped output that can be displayed by
expanding the tree under the job.
Figure 5-4 OS Monitoring - Jobs list
The color of the job output represents the job status:
򐂰
򐂰
򐂰
򐂰
Green - Successful run
Brown - Warnings occurred during the run
Red - Errors occurred during the run
Blue - Running jobs
To view the output of a job, double click the job.
Groups and Profiles are definitions that may be used by other jobs - they do not produce an
output in themselves.
As shown in Figure 5-4, all objects created within Tivoli Storage Resource Manager are
prefixed with the user ID of the creator. Default definitions, created during product installation,
are prefixed with Tivoli.Default.
Groups, Discovery, Probes, Scans, and Profiles are explained in the following sections.
5.1.2 Groups
Before defining monitoring and management jobs, it may be useful to group your resources
so that you can limit the scope of monitoring or data collection.
Figure 5-5 shows the groups you can create with Tivoli Storage Resource Manager.

Figure 5-5 Tivoli Storage Resource Manager Groups
Computer Groups
Computer Groups allow you to target management jobs on specific computers based on your
own criteria. Some criteria you might consider for grouping computers are platform type,
application type, database type, and environment type (for example, test or production).
Our lab environment contains:
򐂰
򐂰
򐂰
򐂰
򐂰
UNIX servers
Windows 2000 servers
MS SQL-Server databases

In order to target specific servers for monitoring based on OS and/or database type, we will
define these four groups:
򐂰
򐂰
򐂰
򐂰
Windows Systems
UNIX System
Windows DB Systems
NAS Devices
To create the first group, expand Groups -> Computer, right-click Computer and select New
Computer Group. Our first group will contain all UNIX systems as shown in Figure 5-6. To
add or remove a host from the group, highlight it in either the Available or Current Selections
panel and use the arrow buttons. You can also enter a meaningful description in the field.
Chapter 5. Operations: Policy, Quotas, and Alerts
163
Figure 5-6 Computer Group definition
To save the new Group, click the floppy disk icon in the menu bar, and enter the Group name
in the confirmation box shown in Figure 5-7.
Figure 5-7 Save a new Computer Group
We created the other groups using the same process, and named them Windows Systems,
Windows DB Systems, and NAS Devices.
Important: To avoid redundant data collection, a computer can belong to only one Group
at a time. If you add a system which is already in a Group, to a second Group, it will
automatically be removed from the first Group.
Figure 5-8 shows the final Group configuration, with the members of the Windows Systems
group.
164
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 5-8 Final Computers Group definitions
Note: The default group Tivoli.DefaultComputerGroup contains all servers that have been
discovered, but not yet assigned to a Group.
Filesystem Groups
Filesystem Groups are used to associate together filesystems from different computers that
have some commonality. You can then use this group definition to focus the Scan and the
Alert processes to those filesystems.
To create a Filesystem Group, you have to select explicitly each filesystem for each computer
you want to include in the group. There is no way to do a grouped selection, e.g. / (root)
filesystem for all UNIX servers or C:\ for all Windows platforms. Figure 5-9 shows the
Filesystem Group definition screen.
Chapter 5. Operations: Policy, Quotas, and Alerts
165
Figure 5-9 Filesystem Group definition
Note: As for computers, a filesystem can belong to only one Group.
Directory GROUPS
Use Directory Groups to group together directories to which you want to apply the same
storage management rules.
Figure 5-10 shows the Directory Group definition screen.
166
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 5-10 Directory group definition
The Directory Group definition has two views for directory selection:
򐂰 Use directories by computer to specify several directories for one computer.
򐂰 Use computers by directory to specify one directory for several computers.
The button on the bottom of the screen toggles between New computer and New directory
depending on the view you select.
We will define one Directory Group with /tmp for all computers, and another with the Oracle
log directory for a specific computer (DIOMEDE). To define the first Group:
1. Select computers by directory.
2. Click on New directory.
3. Enter /tmp in the Directory field and select All computers (see Figure 5-11).

Figure 5-13 Final Directories Group definition
User Groups
You can define Groups made up of selected user IDs. These groupings will enable you to
easily define and focus storage management rules such as scanning and Constraints on the
defined IDs.
Note: You can include in a User Group only user IDs defined on the discovered hosts,
which have files belonging to them.
Figure 5-14 shows the list of available users at a specific point in time.
Chapter 5. Operations: Policy, Quotas, and Alerts
169
Figure 5-14 List of available users
As shown in Example 5-1, we added a new user on the Agent DIOMEDE and created some
files for the user. We than ran a new Scan.
Example 5-1 Create user and files
root@brazil> mkgroup -'A' itso_grp
root@brazil> mkuser pgrp=itso_grp home=/home/itso_usr itso_usr
root@brazil> chown itso_usr:itso_grp /home/itso_usr
root@brazil> su - itso_usr
$ pwd
/home/itso_usr
$ echo "hello" > myfile
$ ls -l myfile
-rw-r--r-1 itso_usr itso_grp
6 Sep 13 11:46 myfile
Now, Figure 5-15 shows that this user ID (itso_usr) is listed in the Available user’s list.
170
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 5-15 List of available user after Scan
Note: As for computers, a user can be defined in only one Group.
OS User Group Groups
You can define Groups consisting of operating system user groups such as Administrators for
Windows or adm for UNIX. To define a Group consisting of user groups, select OS User
Group from the Groups entry on the left hand panel.
Note: As for users, an OS User Group will be added to the list of available Groups only
when a Scan job finds at least one file owned by a user belonging to that Group.
Note: As for users, an OS User Group can belong to only one Group at a time.

Use IBM Tivoli SRM -> Monitoring -> Discovery to change the settings of the Discovery
job. The following options are available.
When to run tab
The initial tab When to Run, (Figure 5-17) is used to modify the scheduling settings. You can
specify to execute the discovery:
򐂰 Now - Run once when the job is saved.
򐂰 Once - at a specified time in the future
򐂰 Repeatedly - Choose the frequency in minutes, hours, days, weeks, or months. You can
limit the run to specific days of the week.

5.1.4 Pings
Figure 5-19 summarizes the Ping process.
Tivoli Storage Resource Manager Ping process
The Ping process will
launch TCP/IP pings against monitored computers
generate statistics on computer Availability in the central repository
generate an Alert if the process fails because of an unavailable host
ibm.com/redbooks
Figure 5-19 Ping process
Pings gather statistics about the availability of monitored servers. The scheduled job will Ping
your servers and consider them active if it gets an answer. This is purely ICMP-protocol
based - there is no measurement of individual application availability. When you create a new
Ping job, you can set the following options.
Computers tab
Figure 5-20 shows the Computers tab, which is used to limit the scope of the computers that
are to be Pinged.
174
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 5-20 Ping job configuration - Computers
When to Ping tab
The tab, When to PING, sets the frequency used for checking. We selected a frequency of 10
minutes as shown in Figure 5-21.
Figure 5-21 Ping job configuration - When to Ping
Options tab
On the Options tab, you specify how often the Ping statistics are saved in the database
repository. By default, Tivoli Storage Resource Manager keeps its Ping statistics in memory
for one hour before flushing them to the database and calculating an average availability. You
can change the flushing interval to another time amount, or a number of Pings (for example,
to calculate availability after every 10 Pings). The system availability is calculated as:
(Count of successful pings) / (Count of pings)
Chapter 5. Operations: Policy, Quotas, and Alerts
175
A lower interval can increase database size, but gives you more accuracy on the availability
history.
We selected to save to the database at each Ping, which means we will have an availability of
100% or of 0%, but we have a more granular view of the availability of our servers.
Alerts tab
The Alerts tab (shown in Figure 5-22) is used to generate Alerts for each host that is
unavailable. Alert mechanisms are explained in more detail in 5.2, “OS Alerts” on page 189.
You can choose any Alert type from the following:
򐂰 SNMP trap to send a trap to the Event manager defined in Administrative services —>
Configuration —> General —> Alert Disposition
򐂰 Login Notification to direct the Alert to the specified user in the Alert Log (see 5.2, “OS
Alerts” on page 189)
򐂰 Windows Event Log to generate an event to the Windows event log
򐂰 Run Script to run a script on the specified server
򐂰 Email to send a mail to the specified user through the Mail server defined in
Administrative services -> Configuration -> General -> Alert Disposition
Figure 5-22 Ping job configuration - Alert
We selected to:
򐂰 Send e-mail to two users
򐂰 Run a script that will send popup messages to selected administrators. The script is listed
in Example 5-2. Optimally, you would send an event to a central console such as the Tivoli
Enterprise Console. Note that certain parameters are passed to the script - more
information is given in “Alerts tab” on page 195.
Example 5-2 Script PINGFAILED.BAT
net send /DOMAIN:a23blvag Computer %1 did not respond to last %2 ping(s). Please check it
176
IBM Tivoli Storage Resource Manager: A Practical Introduction
We then saved the Ping job as PingHosts, and tested it by right-clicking and selecting Run
now. As the hosts GALLIUM and CRETE did not respond, we received:
򐂰 One popup for GALLIUM (Figure 5-23)
Figure 5-23 Ping failed popup for GALLIUM
򐂰 A similar popup for CRETE
򐂰 One e-mail for GALLIUM (Figure 5-24)
Figure 5-24 Mail message for GALLIUM
򐂰 A similar e-mail for CRETE

This tab has the same configuration as for the Ping process.
We set up a weekly Probe to run on Sunday for all computers. We recommend running the
Probe job at a time where all the production data you want to monitor is available to the
system.

5.1.6 Profiles
The main functionality of Profiles is explained in Figure 5-28.
Tivoli Storage Resource Manager Profiles
Profiles are used
in Scan jobs
to limit files to be scanned
to specify files attibutes to be scanned
to select the summary view
directories and filesystems
user ids
OS user groups
to set statistics retention period
Tivoli Storage Resource Manager provides default profiles that
provide data for all the default reports
ibm.com/redbooks
Figure 5-28 Profiles
Profiles are used in Scan jobs to specify:
򐂰
򐂰
򐂰
򐂰
The pattern of files to be scanned
The attributes of files to be gathered
The summary view that will be available in reports
The statistics retention period
Specifying correct profiles avoids gathering unneeded information that may lead to space
problems within the Tivoli Storage Resource Manager repository. However, you will not be
able to report on or check Quotas on files that are not used by the Profile.
Tivoli Storage Resource Manager comes with several default profiles, (shown in Table 5-1)
prefixed with Tivoli.Default, which can be reused in any Scan jobs you define.
Table 5-1 Default profiles
180
Default profile name
Description
BY_ACCESS
Gathers statistics by length of time since last access of files
BY_CREATION
Gathers statistics by length of time since creation of files
BY_MOD_NOT_BACKED_UP
Gathers statistics by length of time since last modification (only for
files not backed up since modification). Windows only
BY_MODIFICATION
Gathers statistics by length of time since last modification of files
IBM Tivoli Storage Resource Manager: A Practical Introduction
Default profile name
Description
LARGEST_DIRECTORIES
Gathers statistics on the n largest directories. (20 is the default
amount.)
LARGEST_FILES
Gathers statistics on the n largest files. (20 is the default amount.)
LARGEST_ORPHANS
Gathers statistics on the n largest orphan files. (20 is the default
amount.)
MOST_AT_RISK
Gathers statistics on the n files that have been modified the longest
time ago and have not yet been backed up since they were
modified. Windows only. (20 is the default amount.)
OLDEST_ORPHANS
Gathers statistics on the n oldest orphan files. (20 is the default
amount.)
SIZE_DISTRIBUTION
Gathers information on the size distribution of files
MOST_OBSOLETE_FILES
Gathers statistics on the n “most obsolete” files (i.e., files that have
not been accessed or modified for the longest period of time). (20
is the default amount.)
SUMMARY_BY_FILESYSTEM
/DIRECTORY
Summarizes space usage by Filesystem or Directory
SUMMARY_BY_GROUP
Summarizes space usage by OS Group
SUMMARY_BY_OWNER
Summarizes space usage by Owner
Those default profiles, when set in a Scan job, gather data needed for all the default Tivoli
Storage Resource Manager reports.
As an example, we will define an additional Profile to limit a Scan job to the 500 largest
Postscript or PDF files unused in the last six months. We also want to keep weekly statistics
at a filesystem and directory level for two weeks.
Statistics tab
On the Statistics tab (shown in Figure 5-29), we specified:
򐂰 Retain filesystem summary for two weeks
򐂰 Gather data based on creation data
򐂰 Select the 500 largest files
The Statistics tab is used to specify the type of data that is gathered, and has a direct
impact on the type of reports that will be available. In our specific case, the Scan associated
with this profile will not create data for reports based on user IDs and users groups. Neither
will it create data for reports on directory size.
Chapter 5. Operations: Policy, Quotas, and Alerts
181
Figure 5-29 New Profile - Statistics tab
The Summarize space usage by section of the Statistics tab specifies how the space usage
data must be summarized. If no summary level is checked, the data will not be summarized,
and therefore will not be available for reporting in the corresponding level of Usage Reporting
section of Tivoli Storage Resource Manager.
In our particular case, because we select to summarize by filesystem and directory, we will
see space used by PDF and Postscript files at those levels, providing we set up the Scan
profile correctly. See 5.1.7, “Scans” on page 185 for information on this. We will not see which
users or groups have allocated those PDF and Postscript files.
Restriction: For Windows servers, users and groups statistics will not be created for FAT
filesystems.
The Accumulate history section sets the retention period of the collected data. In this case,
we will see a weekly summary for the last two weeks.
The Gather statistics by length of time since section sets the base date used to calculate the
file load. It determines if data will be gathered and summarized for the IBM Tivoli SRM ->
Reporting -> Usage -> Files reporting view.
The Gather information on the section sets the amount of files to retrieve for each of the
report views available under IBM Tivoli SRM -> Reporting -> Usage -> Access Load.
Files filter tab
The Files filter tab is used to limit the scope of files that are returned by the Scan job. To
create a selection, right-click on the All files selected context-menu option as shown in
Figure 5-30.
182
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 5-30 New Profile - File filter
With the New Condition menu, you can create a single filter on the files while the New
Group enables you to combine several conditions with:
All of
Any of
None of
Not all of
The file is

The file is
selected if all conditions are met (AND)
selected if at least one condition is met (OR)
NOT selected if at least one condition is met (NOT OR)
selected if none of the conditions are met (NOT AND)
The Condition Group can contain individual conditions or other condition groups.
Each individual condition will filter files based on one of the listed items:
򐂰

We want to select files that meet our conditions: (name is *.ps or name is *.pdf) and
unused since six months. The AND between our two conditions will be translated to All of,
while the OR within our first condition will be translated to Any of.
On the screen shown in Figure 5-30, we selected New Group. From the popup screen,
Figure 5-31, we selected All of and clicked OK.
Chapter 5. Operations: Policy, Quotas, and Alerts
183
Figure 5-31 New Condition Group
Now, within our All of group we will create one dependant Any of group using the same
sequence. The result is shown in Figure 5-32.
Figure 5-32 New Profile - Conditions Groups
Now, we create individual conditions within each group by right-clicking on New Condition on
the group where the conditions must be created. Figure 5-33 shows the creation of our first
condition for the Any of group. We enter in our file specifications (*.ps and *.pdf) here.
Figure 5-33 New Profile - New condition
We repeated the operation for the second condition (All of). The final result is shown in
Figure 5-34.
184
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 5-34 New Profile - Conditions
The bottom of the right pane shows the textual form of the created condition. You can see that
it corresponds to our initial condition. We saved the profile as PS_PDF_FILES (Figure 5-35).

5.1.7 Scans
We explain in Figure 5-36 the main objectives of the Scan jobs.
Chapter 5. Operations: Policy, Quotas, and Alerts
185
Tivoli Storage Resource Manager Scan process
The Scan process is used
to gather data about files
to summarize Usage statistics
as specified in the associated profiles
Mandatory for Quotas and Constraints management
ibm.com/redbooks
Figure 5-36 Scans
The Scan process gathers statistics about the usage and trends of the server storage. Scan
jobs results are stored in the repository and supply the data necessary for the Capacity,
Usage, Usage Violations, and Backup Reporting facilities. To create a new scan job, IBM
Tivoli SRM -> Monitoring -> Scans, right-click and select New scan. The scope of each
Scan job is set by five different tabs on the right pane.
Filesystems tab
You can specify a specific filesystem for one computer, a filesystem Group (see “Filesystem
Groups” on page 165) or all filesystems for a specific computer. Only the filesystems you
have selected will be scanned. Figure 5-37 shows how to configure the Scan to gather data
on all our servers.
Note: Only filesystems found by the Probe process will be available for Scan.
186
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 5-37 New Scan configuration - Filesystem tab
Directory Groups tab
Use this tab to extend the scope of the Scan and also summarize data for the selected
directories. Only directories in the previously selected filesystems will be scanned.
Profiles tab
As explained in 5.1.6, “Profiles” on page 180, the Profiles are used to select the files that are
scanned for information gathering. A Scan job scans and gathers data only for files that are
scoped by selected Profiles. You can specify Profiles at two levels:
򐂰 Filesystems: All selected filesystems will be scanned and data summarized for each
filesystem.
򐂰 Directory: All selected directories (if included in the filesystem) will be scanned and data
summarized for each directory.
Figure 5-38 shows how to configure a Scan to have data summarized at both the filesystem
and directory level.
Chapter 5. Operations: Policy, Quotas, and Alerts
187
.
Figure 5-38 New Scan configuration - Profiles tab
When to Scan tab
As for the Probe and Ping jobs, the scheduling of the job is specified on the When to Scan tab.
Alert tab
You can be alerted through mail, script, Windows Event Log, SNMP trap, or Login notification
if the Scan job fails. The Scan job may fail if an Agent is unreachable.
Click on the floppy icon to save your new Scan job, shown in Figure 5-39.
Figure 5-39 New Scan - Save
Putting it all together
Table 5-2 summarizes the reports views for filesystems and directories that will be available
depending on the settings of the Profiles and the Scan jobs. We assume the Profiles have
been defined with the Summarize space by Filesystem/Directory option. Note that in order
to get reports by filesystem or directory, you need to select either or both in the Scan Profile.

5.2 OS Alerts
Tivoli Storage Resource Manager enables you to define Alerts on computers, filesystems,
and directories. Once the Alerts are defined, it will monitor the results of the Probe and Scan
jobs, and will trigger an Alert when the threshold or the condition is met.
Tivoli Storage Resource Manager provides a number options for Alert mechanisms from
which you can choose depending on the severity you assign to the Alert.
Figure 5-40 shows the Alert mechanisms provided by Tivoli Storage Resource Manager.

Depending on the severity of the triggered event or the functions available in your
environment, you may want to be alerted with:
򐂰 An SNMP trap to an event manager. Figure 5-41 shows a Filesystem space low Alert as
displayed in our SNMP application, IBM Tivoli NetView. Defining the event manager is
explained in “Alert Disposition” on page 114.
Figure 5-41 Alert - SNMP trap sample
򐂰 A TEC event. See Chapter 5., “Operations: Policy, Quotas, and Alerts” on page 159.
190
IBM Tivoli Storage Resource Manager: A Practical Introduction
򐂰 An entry in the Alert Log (see Figure 5-42). You can configure Tivoli Storage Resource
Manager, so that the Alert Log will be automatically displayed when you log on to the GUI
by using Preferences -> Edit General (see Figure 5-43).
Figure 5-42 Alert - Logged alerts sample
Figure 5-43 Alert - Preferences
򐂰 An entry in the Windows Event log, as shown in Figure 5-44. This is useful for lower
severity alerts or when you are monitoring your Windows event logs with an automated
tool such as IBM Tivoli Distributed Monitoring.

򐂰 Running a specified script - The script runs on the specified computer with the authority of
the Agent (root or Administrator). See 5.3.5, “Scheduled actions” on page 229 for special
considerations with scripts execution.
򐂰 An e-mail - Tivoli Storage Resource Manager must be configured with a valid SMTP
server and port as explained in “Alert Disposition” on page 114. Figure 5-45 shows an
example of e-mail notification.

Except for the Alert Log, you can create multiple definitions for each of those Alert features of
Tivoli Storage Resource Manager. To create a new definition, right-click on the feature and
select New <feature>. Figure 5-47 shows how to create a new Filesystem Alert.
Chapter 5. Operations: Policy, Quotas, and Alerts
193
Figure 5-47 Filesystem alert creation
5.2.2 Computer Alerts
Computer Alerts act on the output of Probe jobs (see 5.1.5, “Probes” on page 177) and
generate an Alert for each computer that meets the triggering condition. Figure 5-48 shows
the configuration screen for a Computer Alert.
194
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 5-48 Computer alerts - Alerts
Alerts tab
The Alerts tab contains two parts:
򐂰 Triggering condition to specify the computer component you want to be monitored. You
can monitor a computer for:
–
–
–
–
–
–
–
–
–
–
RAM increased
RAM decreased
Virtual Memory increased
Virtual Memory decreased
New disk detected
Disk not found
New disk defect found
Total disk defects exceed. You will have to specify a threshold.
Disk failure predicted
New filesystem detected
Information about disk failures is gathered through commands against disks with the
following exceptions:
– IDE disks do support only Disk failure predicted queries
– AIX SCSI disks do not support failures and predicted failures queries
򐂰 Triggered action where you specify the action that must be executed. Available actions are
described in Figure 5-40. If you choose to run a script, it will receive several positional
parameters that depends on the triggering condition. The parameters display on the
Specify Script panel, which is accessed by checking Run Script and clicking the Define
button.
Figure 5-49 shows the parameters passed to the script for a RAM decreased condition.
Chapter 5. Operations: Policy, Quotas, and Alerts

This limits the Alert process to specific computers or computer Groups (Figure 5-51).
Figure 5-51 Computer alerts - Computers tab
196
IBM Tivoli Storage Resource Manager: A Practical Introduction
5.2.3 Filesystem Alerts
Filesystem Alerts will act on the output of Probe and Scan jobs and generate an Alert for each
filesystem that meets the specified threshold. Figure 5-52 shows the configuration screen for
a Filesystem Alert.
Figure 5-52 Filesystem Alerts - Alert
Alerts tab
As for Computer Alerts, the Alerts tab contains two parts. In the Triggering condition section
you can specify to be alerted if a:
򐂰 Filesystem is not found, which means the filesystem was not mounted during the most
recent Probe or Scan.
򐂰 Filesystem is reconfigured.
򐂰 Filesystem free space is less than a threshold specified in percent, KB, MB, or GB.
򐂰 Free UNIX filesystem inode count is less than a threshold (either percent or inodes count).
You can choose to run a script (click the Define button next to Run Script), or you can also
change the content of the default generated mail by clicking on Edit Email. You will see a
popup with the default mail skeleton which is editable. Figure 5-53 shows the default e-mail
message.
Chapter 5. Operations: Policy, Quotas, and Alerts
197
Figure 5-53 Filesystem alert - Freespace default mail
5.2.4 Directory Alerts
Directory Alerts will act on the output of Scan jobs.
Alerts tab
Directory Alerts configuration is similar to Filesystem alerts. The supported triggers are:
򐂰 Directory not found
򐂰 Directory consumes more than the specified threshold set in percent, KB, MB or GB.
Directories tab
Since Probe jobs do not report on directories and Scan jobs report only on directories. if a
directory Profile has been assigned (See “Putting it all together” on page 188) you can only
choose to be alerted for any directory that has already been included in a Scan and actually
scanned.
5.2.5 Alert logs
The IBM Tivoli SRM -> Alerting -> Alert log menu (Figure 5-54) lists all Alerts that have
been generated.
198
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 5-54 Alerts log
There are eight different views. Each of them will show only the Alerts related to the selected
view except:
򐂰 All view - Shows all Alerts
򐂰 Alerts Directed to <logged user> - Shows all Alerts where the current logged user has
been specified in the Login notification field
When you click on the icon on the left of a listed Alert, you will see detailed information on the
selected Alert as shown in Figure 5-55.
Chapter 5. Operations: Policy, Quotas, and Alerts
199
Figure 5-55 Detailed Alert information
5.3 Policy management
The Policy Management functions of Tivoli Storage Resource Manager enable you to:
򐂰 Define a filesystem extension policy can be used to automatically increase filesystem
capacity for managed hosts when utilization reaches a specified level. The LUN
provisioning option can be enabled to extend filesystems within an ESS.
򐂰 Define space limits (Quotas) on storage resources used by user IDs and user groups. This
limits can be set at a network (whole environment) at a computer and at a filesystem level.
򐂰 To define space limits (Quotas) on NAS resources used by user IDs and user groups
򐂰 To perform checks (Constraints) on specific files owned by the users and perform any
action on those files
򐂰 To schedule scripts against your storage resources

Figure 5-56 Filesystem Extension
We use filesystem extension policy to automatically extend filesystems when utilization
reaches a specified threshold. We can also enable LUN provisioning to extend filesystems
within an ESS.
To setup filesystem extension policy, select IBM Tivoli SRM -> Policy Management ->
Filesystem Extension. Right click on Filesystem Extension and select Create Filesystem
Extension Rules. The screen in Figure 5-57 displays.
Chapter 5. Operations: Policy, Quotas, and Alerts
201
Figure 5-57 Filesystem tab
In the Filesystems tab, select the filesystems which will use filesystem extension policy by
moving them to the Current Selections panel. In Figure 5-57 we selected the /opt filesystem.
Note the Enabled checkbox - the default is to check it, meaning the rule will be active. If you
uncheck the box, it will toggle to Disabled - you can still save the rule, but the job will not run.
To specify the extension parameters, select the Extension tab (Figure 5-58).
Figure 5-58 Extension tab
This tab specifies how a filesystem will be extended. Here are the fields.
Amount to Extend
We have the following options:
202
IBM Tivoli Storage Resource Manager: A Practical Introduction
򐂰 Add - the amount of space used for extension in MB or GB, or as a percentage of
filesystem capacity.
򐂰 Make Freespace - the amount of freespace that will be maintained in the filesystems by
this policy. If freespace falls below the amount that is specified, the difference will be
added. Freespace can be specified in MB or GB increments, or by a percentage of
filesystem capacity.
򐂰 Make Capacity - the total capacity that will be maintained in the selected filesystems. If
the capacity falls below the amount specified, the difference will be added.
Limit Maximum Filesystem Capacity?
When this option is enabled, the Filesystem Maximum Capacity is used in conjunction with
the Add or Make Freespace under Amount to Extend. If you enter a maximum capacity for a
filesystem in the Filesystem Maximum Capacity field, if a filesystem reaches the specified
size, the filesystem will be removed from the policy and an Alert will be triggered.
Condition for Filesystem Extension
The options are:
򐂰 Extend filesystems regardless of remaining freespace - the filesystem will be
expanded regardless of the available free space.
򐂰 Extend filesystems when freespace is less than - defines the threshold for the
freespace which will be used to trigger the filesystem expansion. If freespace falls below
this value, the policy will be executed. Freespace can be specified in MB or GB
increments, or by a percentage of filesystem capacity.
Note: If you select Make Capacity under Amount to Extend, the Extend filesystems
when freespace is less than option is not available.
Use LOG ONLY Mode
Enable Do Not Extend Filesystems - Log Only when you want the policy to log the
filesystem extension. The extension actions that would have taken place are written to the log
file, but no extension takes place.
In the Provisioning tab (Figure 5-59) we define LUN provision parameters. Note that LUN
provisioning is available at the time of writing for filesystems on an ESS only.
Chapter 5. Operations: Policy, Quotas, and Alerts
203
Figure 5-59 LUN provisioning tab
LUN Provisioning is an optional feature for filesystem extension. When the Enable
Automatic LUN Provisioning is selected, LUN provisioning is enabled.
In the Create LUNs that are at least field, you can specify a minimum size for new LUNs. If
you select this option, LUNs of at least the size specified will be created. If no size is
specified, then the Amount to Extend option specified for the filesystem (in “Amount to
Extend” on page 202) will be used. For more information on LUN provisioning, see IBM Tivoli
Storage Resource Manager 1.2 User’s Guide.
The Model for New LUNs feature means that new LUNs will be created similar to existing
LUNs in your setup. At least one ESS LUN must be currently assigned to the Tivoli Storage
Resource Manager Agent associated with the filesystem you want to extend. There are two
options for LUN modeling:
򐂰 Model new LUNs on others in the volume group of the filesystem being extended provisioned LUNS are modeled on existing LUNs in the extended filesystem’s volume
group.
򐂰 Model new LUNs on others on the same host as the filesystem being extended provisioned LUNS are modeled on existing LUNs in the extended filesystem’s volume
group. If the corresponding LUN model cannot satisfy the requirements. it will look for
other LUNs on the same host.
The LUN Source option defines the location of the new LUN in the ESS, and has two options:
򐂰 Same Storage Pool - provisioned LUNs will be created using space in an existing Storage
Pool. In ESS terminology this is called the Logical Sub System or LSS.
򐂰 Same Storage Subsystem - provisioned LUNs can be created in any Storage Pool or
ESS LSS.
The When to Enforce Policy tab (Figure 5-60) specifies when to apply the filesystem
extension policy to the selected filesystems.
204
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 5-60 When to Enforce Policy tab
The options are:
Enforce Policy after every Probe or Scan automatically enforces the policy after every
Probe or Scan job. The policy will stay in effect until you either change this setting or disable
the policy.
Enforce Policy Now enforces the policy immediately for a single instance.
Enforce Policy Once at enforces the policy once at the specified time, specifying the month,
day, year, hour, minute, and AM/PM
The Alert tab (Figure 5-61) can define an Alert that will be triggered by the filesystem
extension job.
Chapter 5. Operations: Policy, Quotas, and Alerts
205
Figure 5-61 Alert tab
Currently the only available condition is A filesystem extension action started
automatically.
Refer to “Alerts tab” on page 176 for an explanation of the definitions.
Important: After making configuration changes to any of the above filesystem extension
options, you must save the policy, as shown in Figure 5-62. If you selected Enforce Policy
Now, the policy will be executed after saving.

In the Extension tab we specified the following values as shown in Figure 5-64:
򐂰 Extend the filesystem by 64MB
򐂰 Extend filesystem regardless of remaining freespace
Figure 5-64 Extension parameters
We do not need to define anything in the Provisioning tab as the rootvg is not on an ESS. In
When to Enforce Policy we specified Enforce policy: Now, this means that the policy will be
executed only once.
Under Alert, we chose to send an SNMP trap and TEC event when a filesystem extension
action was triggered as shown in Figure 5-65.

As you can see from Figure 5-68 the policy was executed three times so the new filesystem
size should be 64 MB (original size) + 3 x 64 MB (the increment defined in extension policy) =
256 MB and this is the size which is displayed in Example 5-4.
Expanding the filesystem in volume group on ESS (LUN provisioning)
For this example we used a filesystem defined on a volume group, essvg1 using an ESS
LUN. Example 5-5 shows the volume group definition.
Example 5-5 essvg1 volume group definition
# lsdev -Cc disk

hdisk1 Available

Data Path Optimizer Pseudo Device Driver
essvg1) 30918921 = hdisk1 (Avail ) hdisk2 (Avail )
The volume group is defined on the vpath0 device which represents an ESS LUN with serial
number 30918921. The vpath device is used as we have two paths to the physical LUN. See
the Subsystem Device Driver documentation for explanation of vpath device functionality.
The filesystem is mounted on /essfs1 and is defined on logical volume /dev/lv00 as shown in
Example 5-4. The command lslv lv00 shows the information about the logical volume,
including its containing volume group. See Example 5-6.

In Example 5-4 you can see the current /essfs1 filesystem size which is 2.56GB.
We will now define the Filesystem Expansion Rule following the steps in “Expanding the
filesystem in rootvg (no LUN provisioning)” on page 207.
Chapter 5. Operations: Policy, Quotas, and Alerts
211
We selected /essfs1 as the filesystem for expansion as shown in Figure 5-69.
Figure 5-69 /essfs1 filesystem expansion definition
The Extension parameters are shown in Figure 5-70.
Figure 5-70 Extension parameters for /essfs1 FS
We defined to add 2GB on each expansion, which will trigger when the filesystem has less
than 75% free space.
As the volume group is on an ESS, we defined Provisioning parameters (Figure 5-71).
212
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 5-71 Provisioning parameters
We defined to model the LUNs on LUNs which are already in the volume group, and to create
them anywhere in the ESS.
In When to Enforce Policy we specified Enforce policy: Now, this means that the policy will
be executed only once or when we will manually run it.
In the Alert tab we defined to send an SNMP trap and TEC event when a filesystem extension
action was triggered.
We saved the rule and called it essfs1 extension.
Now we create some data to fill the disk. Example 5-7 shows /essfs1 at 80% utilization.

Now we run the filesystem extension policy. Figure 5-72 shows the filesystem extension was
successfully completed, extending /essfs1 by 2GB.

IBM Tivoli Storage Resource Manager: A Practical Introduction
The size of the newly created LUN was as specified in the filesystem expansion rule. Even
though we selected to model LUNs after existing LUNs in the volume group, the size was
defined by the filesystem expansion as it is not part of the modeling algorithm.
Tip: If you wish to maintain the same LUN size in the volume group, it is recommended to
match the filesystem expansion size to the size of the LUNs used in volume group.
From the new LUN serial number 20018921 as shown in Example 5-12 we can see that it was
created in a different Storage Pool or LSS inside the ESS. The original LUN was in LSS 0x13
(as identified by serial number which starts with 3xx) and the new one is in LSS 0x12 (as
identified by serial number starting with 2xx). The reason for the new LUN being created in
another LSS is that the original LSS is full, therefore there is no space for new LUNs. We
selected the option to create new LUNs anywhere in the ESS in our expansion rule. You can
see the physical representation of LUNs from the ESS Specialist in Figure 5-74.

On this screen, the selected icon with label 43P_0 represents the host definition in the ESS

5.3.2 Quotas
The main functionality of Quotas are displayed in Figure 5-75.
Chapter 5. Operations: Policy, Quotas, and Alerts
217
Tivoli Storage Resource Manager User Quotas
Help monitor space used by users and user groups
Quotas can be set for
the whole network
specific computers
specific filesystems
Actions triggered through standard Alerting mechanism when
a quota is exceeded
ibm.com/redbooks
Figure 5-75 Quotas
Quotas can be set at either a user or at an OS User Group level. For the OS User Group level,
this could be either an OS User Group, (see “OS User Group Groups” on page 171), or a
standard OS group (such as system on UNIX, or Administrators on Windows). The User
Quotas trigger an action when one of the monitored users has reached the limit while the OS
User group Quotas trigger the action when the sum of space used by all users of monitored
groups has reached the limit. The Quotas definition mechanism is the same for both except
for:
򐂰 The menu tree to use:
– IBM Tivoli SRM -> Policy Management -> Quotas -> User
– IBM Tivoli SRM -> Policy Management -> Quotas -> OS User group
򐂰 The monitored elements you can specify:
– User and user groups for User Quotas
– OS User Group and OS User Group Groups for OS User Group Quota
We will show how to configure User Quotas. User Group Quotas are configured similarly.
Note that the Quota enforcement is soft - that is, users are not automatically prevented from
exceeding their defined Quota, but the defined actions will trigger if that happens. There are
three sub-entries for Quotas: Network Quotas, Computer Quotas, and Filesystem Quotas
Network Quotas
A Network Quota defines the maximum cumulated space a user can occupy on all the
scanned servers. An Alert will be triggered for each user that exceeds the limit specified in the
Quota definition.
218
IBM Tivoli Storage Resource Manager: A Practical Introduction
Use IBM Tivoli SRM -> Policy Management -> Quotas -> User -> Network, right-click and
select New Quota to create a new Quota. The right pane displays the Quota configuration
screen with four tabs.
Users tab
Figure 5-76 shows the Users tab for Network Quotas.
Figure 5-76 User Network Quotas - Users tab
From the Available column, select any user ID or OS User Group you want to monitor for
space usage.
The Profile pull-down menu is used to specify the file types that will be subject to the Quota.
The list will display all Profiles that create summaries by user (by file owner). Select the Profile
you want to use from the pull-down. The default Profile Summary by Owner collects
information about all files and summarizes them on the user level. The ALLGIFFILES profile
collects information about GIF files and creates a summary at a user level as displayed in
Figure 5-77. This (non-default) profile was created using the process shown in 5.1.6,
“Profiles” on page 180.
Chapter 5. Operations: Policy, Quotas, and Alerts
219
Figure 5-77 Profile with user summary
Using this profile option, we can define general Quotas for all files and more restrictive
Quotas for some multimedia files such as GIF and MP3.
Filesystem tab
On the Filesystem tab shown Figure 5-78, select the filesystems or computers you want to be
included in the space usage for Quota management.
Figure 5-78 User Network Quotas - Filesystem tab
In this configuration, for each user, his cumulated space usage on all servers will be
calculated and checked against the Quota limit.
220
IBM Tivoli Storage Resource Manager: A Practical Introduction
When to check
The Quota management is based on the output of the Scan jobs. Therefore, each Quota
definition must be scheduled to run after the Scan jobs that collect the adequate information.
The When to CHECK tab is standard, and allows you to define a one off or a recurring job.
Alert tab
On the Alert tab, specify the Quota limit in: KB, MB or GB, and the action to run when the
Quota is exceeded.
Figure 5-79 User Network Quotas - Alert tab
You can choose from the standard Alerts type available with Tivoli Storage Resource
Manager. Each Alert will be fired once for each user exceeding their Quota. We have selected
to run a script that we wrote, QUOTAUSERNET.BAT, listed in Example 5-14.
Example 5-14 QUOTAUSERNET.BAT script
echo NETWORK quota exceeded - %1 %2 uses %3 - Limit set to %4 >>quotausernet.txt
Example 5-15 shows the output file created by QUOTAUSERNET.BAT.
Example 5-15 Content of quotausernet.txt
NETWORK quota exceeded - user root uses 8.22GB - Limit set to 5.0GB
NETWORK quota exceeded - user Administrators@BUILTIN uses 9.61GB - Limit set to 5.0GB
The Alert has fired for user root and Administrators. This clearly shows that administrative
users such as root and Administrators should not normally be included in standard Quotas
monitoring.
Chapter 5. Operations: Policy, Quotas, and Alerts
221
Computer Quotas
Computer Quotas enable you to fire Alerts when a user exceeds their space Quota on a
specific computer. Multiple Alerts are generated if a user violates the Quota on separate
computers as shown in Figure 5-80.
Figure 5-80 Computer Quota - Alerts log
Here, we received an Alert that the root user exceeded the Quota on the computers CRETE,
SOL-E, BRAZIL, and EASTER. Another Alert was generated for user itso_hb, because it
exceeded the Quota on the system BRAZIL.
Filesystem Quotas
A Filesystem Quota defines a space usage limit at the filesystem level. An Alert will be fired
for each filesystem where a user exceeds the limit specified in the Quota definition.
Use IBM Tivoli SRM -> Policy Management -> Quotas -> User -> Filesystem, right-click,
and select New quota to create a new Quota. After setting up and running a Quota for
selected filesystems, we received the following entries in the Alert History, shown in
Figure 5-81.
222
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 5-81 Filesystem Quota - Alerts log
We see that four Alerts have been fired for CRETE:
򐂰
򐂰
򐂰
򐂰
User bin on /usr
User root on /
User root on /tmp
User root on /user
We also see down to the filesystem level on BRAZIL for the user itso_hb, who generated an
Alert in “Computer Quotas” on page 222.
5.3.3 Network Appliance Quotas
Using IBM Tivoli SRM -> Policy Management -> Network Appliance Quotas ->
Schedules, you can compare the space used by users against Quotas defined inside
Network Appliance filers, using the appropriate software, and raise an Alert whenever a user
is close to reaching the NetApp Quota.
When you run a Network Appliance Quota job, the NetApp Quota definitions will be imported
into Tivoli Storage Resource Manager for read-only purposes.
Note: Network Appliance Quotas jobs must be scheduled after the Scan jobs, since they
use the statistics gathered by the latest Scan to trigger any NetApp Quota violation.
With IBM Tivoli SRM -> Policy Management -> Network Appliance Quotas -> Imported
User Quotas and Imported OS User Group Quotas, you can view the definitions of the
Quotas defined on your NetApp filers.
Chapter 5. Operations: Policy, Quotas, and Alerts
223
5.3.4 Constraints
The main features of Constraints are displayed in Figure 5-75.
Tivoli Storage Resource Manager Constraints
Reports and triggers actions based on specific files which use
too much space on monitored servers
Files can be selected based on
server and filesystem
name pattern (eg: *.mp3, *.avi)
owner
age
size
attributes
Actions triggered through standard Alerting mechanism when
total space used by files exceeds a threshold
ibm.com/redbooks
Figure 5-82 Constraints
Constraints are used to generate Alerts when files matching specified criteria are consuming
too much space on the monitored servers.
Constraints provide a deeper level of Storage Resource Management. Quotas will allow
reporting on users who have exceeded their space limitations. With Constraints, we can get
more detailed information to specify limits on particular file types or other attributes, such as
owner, age, and so on. The output of a Constraint when applied to a Scan will return a list of
the files that are consuming too much space.
Note: Unlike Quotas, Constraints are automatically checked during Scan jobs and do not
need to be scheduled. Also, the Scan does not need to be associated with Profiles that will
cause data to be stored for reporting.
Filesystems tab
This Filesystems tab helps you to select the computers and filesystems you want to be
checked for the current Constraint. The selection method for computers and filesystems is the
same as for Scan jobs (see 5.1.7, “Scans” on page 185).
File Types tab
On the File Types tab, you can explicitly allow or disallow certain file patterns (Figure 5-83).
224
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 5-83 Constraint - File Types
Use the buttons on the top of the screen, to allow or forbid files depending on their name. The
left column shows some default file patterns, or you can use the bottom field to create your
own pattern. Click >> to add your pattern to the allowed/forbidden files.
Users tab
The Users tab (figured in Figure 5-84) is used to allow or restrict the selected users in the
Constraint.
Figure 5-84 Constraint - Users
Chapter 5. Operations: Policy, Quotas, and Alerts
225
Important: The file condition is logically ORed with the User condition. A file will be
selected for Constraint processing if it meets at least one of the conditions.
Options tab
The Options tab provides additional conditions for file selection, and limits the number of
selected files to store in the central repository.
Once again, the conditions added in the tab will be logically ORed with the previous set in the
File Types and Users tab.
The bottom part of the tab, shown in Figure 5-85, contains the textual form of the Condition,
taking into account all the entries made in the Filesystems, File Types, Users and Options
tabs.
Figure 5-85 Constraints - Options
You can change this condition or add additional conditions, by using the Edit Filter button. It
displays the file filter popup (Figure 5-86) to change, add, and remove conditions or
conditions groups as previously explained in 5.1.6, “Profiles” on page 180.
226
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 5-86 Constraints - File filter
We changed the file filter to a more appropriate one by changing the OR operator to AND.
Figure 5-87 Constraints - File filter changed
Alert tab
After selecting the files, you may want to generate an Alert only if the total used space
meeting the Constraint conditions exceeds a predefined limit. Use the Alert tab to specify
the triggering condition and action.
Chapter 5. Operations: Policy, Quotas, and Alerts
227
Figure 5-88 Constraints - Alert
In our Constraint definition, a script is triggered for each filesystem where the selected files
exceed one Gigabyte. We select the script by checking the Run Script option and selecting
Define ... as shown in Figure 5-89. The script will be passed several parameters including a
path to a file that contains the list of files meeting the Constraint. You can use this list to
execute any action including delete or archive commands.
Figure 5-89 Constraints - Script parameters
228
IBM Tivoli Storage Resource Manager: A Practical Introduction
Our example uses a sample script (tsm_arch_del.vbs) which is shipped with Tivoli Storage
Resource Manager, which archives all the files in the produced list to a Tivoli Storage
Manager server, and then deletes them from local storage. This script is installed with the
Tivoli Storage Resource Manager server, and stored in the scripts subdirectory of the server
installation. It can be edited or customized if required - we recommend that you save the
original files first. Versions for Windows (tsm_arch_del.vbs) and UNIX (tsm_arch_del) are
provided. If you will run this Constraint on a UNIX agent, then PERL is required to be installed
on the agent. A Tivoli Storage Manager server must be available and configured for this script
to work. For more information on the sample scripts, see Appendix A of the IBM Tivoli Storage
Resource Manager User’s Guide, SC32-9069.
5.3.5 Scheduled actions
Figure 5-90 shows the main functionality of Scheduled actions.
Tivoli Storage Resource Manager Scheduled actions

Alert raised when a script fails
ibm.com/redbooks
Figure 5-90 Scheduled actions
Tivoli Storage Resource Manager comes with an integrated tool to schedule script execution
on any of the Agents. If a script fails due to an unreachable Agent, the standard Alert
processes can be used. To create a Scheduled action, select Scheduled Actions -> Scripts,
and right-click on New Script.
Computers tab
On the Computers tab, select the computers or computer groups to execute the script.
Script Options tab
From the pull-down field, select a script that exists on the server. You can also enter the name
of a script not yet existing on the server or that only resides on the Agents.
Chapter 5. Operations: Policy, Quotas, and Alerts
229
See 3.2.2, “Scripts” on page 51 for an explanation of server/Agent scripts execution rules.
The Script options tab is shown in Figure 5-91.
Figure 5-91 Scheduled action - Script options
The Script Name pull-down field lists all files (including non-script files) in the servers’ script
directory.
Attention: For Windows Agents, the script must have an extension that has an associated
script engine on the computer running the script (for example: .BAT, .CMD, or .VBS).
For UNIX Agents:
򐂰 The extension is removed from the specified script name
򐂰 The path to the shell (for example, /bin/bsh, /bin/ksh) must be specified in the first line of
the script
If the script is located in a Windows Tivoli Storage Resource Manager Server scripts
directory, the script must have been created on a UNIX platform, and then transferred in
binary mode to the Server or you can use UNIX OS tools such as dos2unix to convert
the scripts. This will ensure that the CR/LF characters are correctly inserted for
execution under UNIX.
When to Run tab
As for other Tivoli Storage Resource Manager jobs, you can choose to run a script once or
repeatedly at a predefined interval.
Alerts tab
With the Alert tab you can choose to be notified when a script fails due to an unreachable
Agent or a script not found condition. The standard Alert Mechanism described in 5.2, “OS
Alerts” on page 189 is used.
5.4 Database monitoring
The Monitoring functions of Tivoli Storage Resource Manager are extended to databases
when the license key for Tivoli Storage Resource Manager for Databases is enabled.
Currently, MS SQL-Server, Oracle, DB2, and Sybase are supported.

We will now review the Groups, Probes, Scans, and Profiles definitions for Tivoli Storage
Resource Manager for Databases, and show the main differences compared to the core Tivoli
Storage Resource Manager monitoring functions.
Figure 5-92 shows the navigation tree for Tivoli Storage Resource Manager for Databases.
Figure 5-92 Databases - Navigation Tree
5.4.1 Groups
To get targeted monitoring of your database assets, you can create Groups consisting of:
򐂰
򐂰
򐂰
򐂰
Computers
Databases-Tablespaces
Tables
Users
Computer Groups
All databases residing on the selected computers will be probed, scanned, and managed for
Quotas.
The groups you have created using Tivoli Storage Resource Manager remain available for
Tivoli Storage Resource Manager for Databases. If you create a new Group, the computers
you put in it will be removed from the Group they currently belong to.
To create a Computer Group, use IBM Tivoli SRM for Databases -> Monitoring -> Groups
-> Computer, right-click, and select New Group.
“Computer Groups” on page 163 gives more information on creating Computer Groups.
Databases-Tablespaces Groups
Creating Groups with specific databases and tablespaces may be useful for applying identical
management rules for databases with the same functional role within your enterprise.
Chapter 5. Operations: Policy, Quotas, and Alerts
231
An example could be to create a group with all the SQL-Server system databases, as you will
probably apply the same rules for space and alerting on those databases. This is shown in
Figure 5-93.
Figure 5-93 Database group definition
Table Groups
You can use Table Groups to create Groups of the same set of tables for selected or all
database instances.
You can use two different views to create a table group:
򐂰 Tables by instance selects several tables for one instance.
򐂰 Instances by table selects several instances for one table.
You can combine both views as each entry you add will be added to the group.
User Groups
As for core Tivoli Storage Resource Manager, you can put user IDs in groups. The user
groups you create will be available for the whole Tivoli Storage Resource Manager product
set.
Tip: The Oracle and MS SQL-Server user IDs (SYSTEM, sa, ...) are also included in the
available users list after the first database Probe.
5.4.2 Probes
The Probe process is used to gather data about the files, instances, logs, and objects that
make up monitored databases. The results of Probe jobs are stored in the repository and are
used to supply the data necessary for Asset Reporting.
Use IBM Tivoli SRM for Databases -> Monitoring -> Probe, right-click, and select New
probe to define a new Probe job. In the Instance tab of the Probe configuration, you can
select specific instances, computers, and computer groups.
232
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 5-94 Database Probe definition
The Computers list contains only computers that have been licensed for Tivoli Storage
Resource Manager for Databases. The product licensing procedure is described in “License
Keys” on page 108.
5.4.3 Profiles
As for Tivoli Storage Resource Manager, Profiles in Tivoli Storage Resource Manager for
Databases are used to determine the databases attributes that are to be scanned. They also
determine the summary level and retention time to keep in the repository.
Use IBM Tivoli SRM for Databases - Monitoring - Profile, right-click, and select New
profile to define a new profile. Figure 5-95 shows the Profile definition screen.
Figure 5-95 Database profile definition
Chapter 5. Operations: Policy, Quotas, and Alerts
233
You can choose to gather data on tables size, database extents, or database free space and
summarize the results at the database or user level.
5.4.4 Scans
Scan jobs in Tivoli Storage Resource Manager for Databases collect statistics about the
storage usage and trends within your databases. The gathered data is used as input to the
usage reporting and Quota analysis.
Defining a Scan job requires defining:
򐂰 The database, computer, and instances to Scan
򐂰 The tables to monitor for detailed information such as size, used space, indexes, rows
count
򐂰 The profile that will determine the data that is gathered and the report views that will be
made available by the Scan
򐂰 The job scheduling frequency
򐂰 Oracle-only additional options to gather information about pages allocated to a segment
that has enough free space for additional rows
򐂰 The alerting mechanism to use should the Scan fail
All this information is set through the Scan definition screen that contains one tab for each
previously listed item. To define a new Scan, select IBM Tivoli SRM for Databases ->
Monitoring -> Scan, right-click and select New scan as in Figure 5-96.
Figure 5-96 Database Scan definition
Note: If you request detailed scanning of tables, the tables will only be scanned if their
respective databases have also been selected for scanning.
234
IBM Tivoli Storage Resource Manager: A Practical Introduction
5.5 Database Alerts
Tivoli Storage Resource Manager for Databases enables you to define Alerts on instances,
databases, and tables. The Probe and Scan jobs output are processed and compared to the
defined alerts. If a threshold is reached, an Alert will be triggered.
Tivoli Storage Resource Manage for Databases uses the standard Alert mechanisms
described in 5.2, “OS Alerts” on page 189.
5.5.1 Instance Alerts
IBM Tivoli SRM for Databases -> Alerting -> Instance Alerts, right-click and select New
alert lets you define some alerts as shown in Table 5-3. Those Alerts are triggered during the
Probe process.
Table 5-3 Instance Alerts
Alert type
Oracle
New database discovered
New tablespace discovered
x
Archive log contains more than X units
x
Sybase
MSSQL
x
x
New device discovered
x
Device dropped
x
Device free space greater than X units
x
Device free space less than X units
x
An interesting Alert is the Archive log contains more than for Oracle, since the Oracle
application can hang if there is no more space available for its archive log. This Alert can be
used to monitor the space used by in this specific directory and trigger a script that will
archive the files to an external manager such as Tivoli Storage Manager once the predefined
threshold is reached. Here is the procedure:
1. We defined an Instance Alert and selected the Archive log contains more than
condition. We also specified that the script ARCHORA.BAT must be executed when the
Alert is fired. Note the parameters passed to the script.
Chapter 5. Operations: Policy, Quotas, and Alerts
235
Figure 5-97 Instance Alert definition
2. As the archive command must run on the server where Oracle resides, we set Triggering
Computer in the Where to run pull-down field. This does not means that the script must be
physically copied on the monitored server.
3. On the Instance tab, we selected our Oracle server (GALLIUM) and we saved the Alert as
ArchiveOracleLog.
Example 5-16 shows a sample script which we have written, ARCHORA.BAT, which will
archive the Oracle logs to a Tivoli Storage Manager server, and then delete them after
archive. It assumes you already have a Tivoli Storage Manager Server and client defined and
configured for your environment. Note this is a sample only, and should be customized and
tested for your environment.

When the Probe job is run against the GALLIUM server, an Alert is fired. You can see its
output in Figure 5-98.
Figure 5-98 Instance Alert output
5.5.2 Database-Tablespace Alerts
To define a Database-Tablespace Alert, select IBM Tivoli SRM for Databases -> Alerting ->
Database-Tablespace Alerts, right-click, and select New alert. You can define various
monitoring options on your databases as shown in Table 5-3. Those Alerts are triggered
during the Probe process.

To avoid a Log Full condition, we will define an Alert to monitor log usage on our MS
SQL-Server database. When the log reaches 70% utilization, the Alert will trigger and
perform a backup of the transaction log.

5.5.3 Table Alerts
To define a new Table Alert, use IBM Tivoli SRM for Databases -> Alerting -> Table Alerts,
right-click, and select New alert. With this option you can set up monitoring on database
tables. The Alerts that can be triggered for a table are shown below. Those Alerts are
triggered during the Scan processes and only if the Scan includes a Table Group.

5.5.4 Alert log
The IBM Tivoli SRM for Database - Alerting - Alert log menu lists all Alerts that have been
fired by the Probe jobs, the Scan jobs, the defined Alerts, and the violated Quotas.
Tip: Please refer to 5.2.5, “Alert logs” on page 198 for more information about using the
Alert log tree.
240
IBM Tivoli Storage Resource Manager: A Practical Introduction
5.6 Databases policy management
The Policy Management functions of Tivoli Storage Resource Manager for Databases enable
you to:
򐂰 Define space limits (Quotas) on database space used by tables owners. Those limits can
be set at a network (whole environment), at an instance or at a database level.
򐂰 Schedule scripts against your database resources
5.6.1 Network Quotas
A Network Quota will define the maximum cumulated space a user can occupy on all the
scanned databases. An Alert will be fired for each user that exceeds the limit specified in the
Quota definition.
We used IBM Tivoli SRM for Databases - Policy Management - Quotas - Network,
right-click and select New quota to create a new Quota. The right pane will switch to a Quota
configuration screen with four tabs.
Users tab
On the Users tab, specify the database users you want to be monitored for Quotas. You can
also select a profile in the Profile pull-down field on the top right of the tab. In this field, you
can select any Profile that stores summary data on a user level. The Quota will only be fired
for databases that have been scanned using this Profile.
Figure 5-100 Database Quota - Users tab
Database-Tablespace tab
Use this tab to restrict Quota checking to certain databases. You can choose several
databases or computers. If you choose a computer, all the databases running on it will be
included for Quota management.
When to run tab
As for Tivoli Storage Resource Manager, you can select the time to run from:
򐂰 Immediate
Chapter 5. Operations: Policy, Quotas, and Alerts
241
򐂰 Once at a schedule date and time
򐂰 Repetitive at predefined intervals
Alert tab
On the Alert tab you can specify the space limit allowed for each user and the action to run. If
no action is selected, the Quota violation will only be logged in the Alert log.
5.6.2 Instance Quota
The Instance Quota mechanism is similar to the Network Quota, except that it is set at the
instance level. Whenever a user reaches the Quota on one instance, an Alert will be fired.
5.6.3 Database Quota
With Database Quota, the Quota is set at the database level. Each monitored user will be
reported back as soon as he reaches the limit on at least one of the monitored database.
5.7 Database administration samples
We now list some typical checks done regularly by Oracle database administrators and show
how they can be automated using Tivoli Storage Resource Manager for Databases.
5.7.1 Database up
Tivoli Storage Resource Manager for Databases can be used to test for database availability
using Probe and Scan jobs since they will fail and trigger an Alert if either the database or the
listener is not available. Since those jobs use system resources to execute, you may instead
choose scheduled scripts to test for database availability.
Due to limited scheduling options and the need for user-written scripts, we recommend using
dedicated monitoring products such as Tivoli Monitoring for Databases.
5.7.2 Database utilization
There are a number of different levels where system utilization can be monitored and checked
in a database environment.
Tablespace space usage
This is a standard Alert provided by Tivoli Storage Resource Manager for Databases. This
Alert will be triggered by the Probe jobs.
Archive log directory space usage
This is a standard alert provided by Tivoli Storage Resource Manager for Databases. This
Alert will be triggered by the Probe jobs as shown in 5.5.1, “Instance Alerts” on page 235.
Maximum extents used
Your application may become unavailable if a table reaches its maximum allowed number of
extents. This is an indicator that can be monitored using the (Max Events - Allocated Extents)
< Table Alert.
242
IBM Tivoli Storage Resource Manager: A Practical Introduction
5.7.3 Need for reorganization
To ensure good application performance, it is important to be notified promptly if a database
reorganization is required.
Count of Used table extents
You can monitor for table reorganization need using the table Alert trigger Segment has more
than n extents.
Count of chained rows
Chained rows can have an impact on database access performance. This issue can be
monitored using the Chained Row Count Greater than table Alert trigger.
Count of Used table extents
You can monitor the need for table reorganization using the table Alert trigger Segment has
more than n extents.
Freelist count
You cannot monitor the count of freelists in an Oracle table using Tivoli Storage Resource
Manager for Databases.

Figure 6-1 Reporting capabilities
The reporting capabilities of Tivoli Storage Resource Manager are very rich, with over 300
predefined views. You can see the data from a very high-level; for example, the total amount
of free space available over the enterprise; or from a low-level, for example, the amount of
free space available on a particular volume or a table in a database.
The data can be displayed in tabular or graphical format, or can be exported as HTML,
Comma Separated Variable (CSV), or formatted report files.
The reporting function uses the data stored in the Tivoli Storage Resource Manager
repository. Therefore, in order for reporting to be accurate in terms of using current data,
regular discovery, Ping, Probe, and Scan jobs must be scheduled. These jobs are discussed
in 5.1, “OS Monitoring” on page 160.
Figure 6-2 shows the Tivoli Storage Resource Manager main screen with the reporting
options highlighted.
The Reporting sections are used for interactive reporting. They can be used to answer ad hoc
questions such as, “How much free space is available on my UNIX systems?” Typically, you
will start looking at data at a high-level and drill down to find specific detail. Much of the
information can also be displayed in graphical form as well as in the default table form.
The My Reports sections give you access to predefined reports. Some of these reports are
pre-defined by Tivoli Storage Resource Manager, others can be created by individual users
248

saving reporting criteria in the Reporting options. You can also set up Batch Reports to create
reports automatically on a schedule.
My Reports will be covered in more detail in 6.5, “Creating customized reports” on page 345,
and 6.6, “Setting up a schedule for daily reports” on page 360.
The additional product, Tivoli Storage Resource Manager for Chargeback produces storage
usage Chargeback data, as described in 6.8, “Charging for storage usage” on page 364.

6.1.1 Major reporting categories
Tivoli Storage Resource Manager collects data for reporting purposes in seven major
categories. These will be covered in the following sections. Within each major category there
are a number of sub-categories.
Most categories are available for both operating system level reporting and database
reporting. However, a few are for operating system reporting only. The description of each
category specifies which applies, and in the more detailed following sections for each
category, we present the capabilities separately for both Tivoli Storage Resource Manager
and Tivoli Storage Resource Manager for Database as appropriate.
Chapter 6. Reporting
249
Asset Reporting
Asset data is collected by Probe processes and reports on physical components such as
systems, disk drives, and controllers. Currently, Asset Reporting down to the disk level is only
available for locally attached devices. Asset Reporting is available for both operating system
and database reporting.
Storage Subsystems Reporting
Storage Subsystem data is collected by Probe processes. It provides a mechanism for viewing
storage capacity at a computer, filesystem, storage subsystem, LUN, and disk level. These
reports also enable you to view the relationships among the components of a storage
subsystem. Storage Subsystem reporting is currently only available for IBM TotalStorage
Enterprise Storage Servers (ESS). Storage Subsystems Reporting is available for operating
system only.
Availability Reporting
Availability data is collected by Ping processes and allows you to report on the availability of
your storage resources and computer systems. Availability Reporting is provided for operating
system reporting only.
Capacity Reporting
Capacity Reporting shows how much storage you have and how much of it is being used. You
can report at anywhere from an entire network level down to an individual filesystem.
Capacity Reporting is provided for both operating system and database reporting.
Usage Reporting
Usage Reporting goes down a level from Capacity Reporting. It is concerned not so much
with how much space is in use, but rather with how the space is actually being used for. For
example, you can create a report that shows usage by user, or a wasted space report. You
define what wasted space means, but it could be for example files of a particular type or files
within a certain directory, which are more than 30 days old. Usage Reporting is provided for
both operating system and database reporting.
Usage Violation Reporting
Usage Violation Reporting allows you to set up rules for the type and/or amount of data that
can be stored, and then report on exceptions to those rules. For example, you could have a
rule that says that MP3 and AVI files are not allowed to be stored on file servers. You can also
set Quotas for how much space an individual user can consume. Not that usage violations
are only softly enforced - IBM Tivoli Storage Resource Manager will not enforce the rules in
real time, but will generate an exception report after the fact. Usage Violation Reporting is
provided for both operating system and database reporting.
Backup Reporting
Backup Reporting identifies files that have not been backed up. Backup Reporting is provided
for operating system reporting only.

Figure 6-3 Tivoli Storage Resource Manager standard reporting
This section discusses Tivoli Storage Resource Manager’s standard reporting capabilities.
Customized reporting is covered in 6.5, “Creating customized reports” on page 345.
This section is not intended to cover exhaustively all of the reporting options available, as
these are very numerous, and are covered in detail in the Reporting section of the manual
IBM Tivoli Storage Resource Manager V1.1 Reference Guide SC32-9069. Instead, this
section provides a basic overview of Tivoli Storage Resource Manager reporting, with some
examples of what types of reports can be produced, and additional information on some of
the less straightforward reporting options.
To demonstrate the reporting capabilities of Tivoli Storage Resource Manager, we installed
the Server code on a Windows 2000 system called LOCHNESS, and deployed these Agents:

A Windows NT workstation called A23BLTZM
AIX systems called BRAZIL and CRETE
An HP-UX system called EASTER
A Solaris system called SOL-E
Windows 2000 servers called GALLIUM, LEAD and VMWAREW2KSR1.
LOCHNESS is also an Agent as well as being the Server.
The host GALLIUM has both Microsoft SQL-Server and Oracle database installed to
demonstrate database reporting. The Agent on LOCHNESS also provides data for a NAS
device call NAS200. The Agent on VMWAREW2KSRV1 also provides data for a NetWare
server called ITSOSJNW6.
The lab setup is shown in Figure 6-4.

is collected (for example, Exports/Sshares), and the specific detail for a given device.
Figure 6-7 Report - GALLIUM assets
By OS Type view
This view of the Asset data provides the same information as the By Computer view, with the
difference that the Agent systems are displayed sorted by operating system platform.
System-wide view
The System-wide view however does provide additional capability, as it can give a
System-wide view rather than a node-by-node view of some of the data. A graphical view of
some of the data is also available. Figure 6-8 shows the options available from the
System-wide view and in the main panel, the report of all exports/shares available.
254
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-8 Reporting - Assets - System-wide view
Each of the options available under the System-wide view are self explanatory with the
possible exception of Monitored Directories. Tivoli Storage Resource Manager can monitor
utilization at a directory level as well as a device or filesystem level. However, by default,
directory level monitoring is disabled.
To enable directory monitoring, define a Directory Group by selecting Tivoli Storage
Resource Manager -> Monitoring -> Groups -> Directory, right-click Directory and choose
New Directory Group. The process of setting up Directory Groups is discussed in more
detail in 5.1.2, “Groups” on page 162. Once the Directory Group is created it must be
assigned to a Scan job, and that job must be run on the systems where the directories to be
monitored exist.
By setting up a monitored directory you will get additional information for that directory. Note
that the information collected includes any subdirectories. Information collected about the
directory tree includes the number of files, number of subdirectories, total space used, and
average file size. This can be graphed over time to determine space usage patterns.
Figure 6-9 shows the directories that we are monitoring.

IBM Tivoli Storage Resource Manager for Databases
Asset Reporting for databases is similar to that for filesystems; however, filesystem entities
like controllers, disks, filesystems, and shares are replaced with database instances,
databases, tables, and data files.
Very specific information regarding an individual database is available as shown in
Figure 6-10 for the database Northwind on node GALLIUM. Or you can see rollup information
for all databases on a given system (using the System-wide view) as shown in Figure 6-11.
256
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-10 Northwind database asset details
Figure 6-11 System-wide view of database assets
All of the database Asset Reporting options are quite straightforward with the exception of
one. In order to receive table level asset information, one or more Table Groups needs to be
Chapter 6. Reporting
257
defined. This is a similar process to that for Directory Groups as described in “System-wide
view” on page 254.
You would not typically include all database tables within Table Groups, but perhaps either
critical or rapidly growing tables. We will set up two groups, one for each database type.
To set up a Table Group, Tivoli Storage Resource Manager for Databases -> Monitoring
-> Groups -> Table, right-click Table and choose New Table Group (Figure 6-12).
Figure 6-12 Create a new database table group
We have entered a description of GALLIUM Table Group. Now we click New Instance to
enter the details of the database and tables that we want to monitor. From the drop down box,
we select the database instance, in this case the SQL-Server instance on GALLIUM. We then
enter three tables in turn. For each table, we entered the database name (Northwind ), the
creator name (dbo) and a table name. After entering the values, click Add to enter more
tables or finish. We entered the table names of Customers, Employees and Suppliers, as
shown in Figure 6-13. Once all of the tables have been entered click OK.
Figure 6-13 Add SQL Server tables to table group
258
IBM Tivoli Storage Resource Manager: A Practical Introduction
We then entered details for a single table called DR$OBJECT for the Oracle database ITSRM
as shown in Figure 6-14.
Figure 6-14 Add Oracle tables to table group
Now we return to the Create Table Group panel, and we see in Figure 6-15 the information
about the newly entered tables.
Figure 6-15 Tables added to table group
Now we chose File -> Save and when prompted, we entered the Table Group name of
GALLIUM Table Group.
In order for the information for our tables to be collected, the Table Group needs to be
assigned to a Scan job. We will assign it to the default database scan job called Tivoli.Default
DB Scan by choosing IBM Tivoli SRM for Databases -> Monitoring -> Scans ->
Tivoli.Default DB Scan. The definition for this scan job is shown in Figure 6-16 and in
particular we see the Table Groups tab. Our new Table Group is shown initially in the left hand
pane. We moved it to the right hand pane by selecting it and clicking >>. We then save the
updates to the Scan job by choosing File -> Save (or with the floppy disk icon from the tool
Chapter 6. Reporting
259
bar). Finally, we can execute the Scan job by right-clicking it and choosing Run Now.
Figure 6-16 shows the Scan job definition after the Table Group had been assigned to it.
Figure 6-16 Table group added to scan job
Example 6-1 on page 261 is an extract from the Scan job log showing that the table
information is now being collected. You can view the Scan job log through the Tivoli Storage
Resource Manager GUI by first expanding the particular Scan job definition. A list of Scan
execution reports will be shown; select the one of interest. You may need to right-click on the
Scan job definition and choose Refresh. The list of Scan executions for the Tivoli.Default DB
Scan is shown in Figure 6-17.
Figure 6-17 Displaying Scan job logs
Once you have the actual job chosen you can click the detail icon for the system that you are
interested in to display the job log. The actual file specification of the log file on the Agent

system will be displayed at the top of the output when viewed through the GUI. Example 6-1
shows the actual file output.

Finally, we can produce table level asset reports by choosing for example, IBM Tivoli SRM

6.2.2 Storage Subsystems Reporting
Storage Subsystems Reporting is covered in detail in 6.3, “Tivoli Storage Resource Manager
ESS Reporting” on page 297.
6.2.3 Availability Reporting
Availability Reporting is quite simple. Two different sets of numbers are reported - Ping and
Computer Uptime. Ping is only concerned with whether or not the system is up and
responding to the ICMP requires - it does not care whether the Tivoli Storage Resource
Manager Agent is running or not. Ping results are collected by a Ping job, so this must be
scheduled to run on a regular basis. See 5.1.4, “Pings” on page 174.
Computer Uptime detects whether or not the Tivoli Storage Resource Manager Agent is
running. Computer Uptime statistics are gathered by a Probe job so this must be scheduled to
run on a regular basis. See 5.1.5, “Probes” on page 177.
Figure 6-19 shows the Ping report for our Tivoli Storage Resource Manager environment, and
Figure 6-20 shows the Computer Uptime report. To generate these reports, we had to select
the computers of interest and select Generate Report.
Figure 6-19 Reports - Availability - Ping

IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-20 Reports - Availability - Computer Uptime
6.2.4 Capacity Reporting
Capacity Reporting shows how much storage capacity is installed, and of that capacity, how
much is being used and how much is available for future growth.
IBM Tivoli Storage Resource Manager
There are four capacity report views within Tivoli Storage Resource Manager:
򐂰
򐂰
򐂰
򐂰
Disk Capacity
Filesystem Capacity
Filesystem Used Space
Filesystem Free Space
However, in reality there are really only two views, or perhaps three. The Filesystem Capacity
and Filesystem Used Space views are nearly identical - the only differences being in the
order of the columns and the row sort order.
And there is relatively little difference between these two views and the Filesystem Free
Space view. The Filesystem Capacity and Filesystem Used Space views report on used
space, so include columns like percent used space whereas Filesystem Free Space includes
columns like percent free space. All other data is identical.
Therefore, there are really only two views: a Disk Capacity view and a Filesystem Capacity
view.
The Disk Capacity view provides information about physical or logical disk devices and what
proportion of them has been allocated. Figure 6-21 shows the Disk Capacity by Disk selection
window.
Chapter 6. Reporting
263
Figure 6-21 Disk capacity report selection window
Often there is a one-to-one relationship between devices and filesystems, particularly on
Windows systems. One of our Windows systems, A23BLTZM, has a single physical disk
which has two partitions. We will select that system to report on by choosing Clear All,
clicking the check box beside the system name, and then choosing Generate Report. This
system has only one disk (Disk 0) which is displayed on the next screen, so we clicked the
detail icon and the report in Figure 6-22 is produced. Note the two partitions show at the
bottom of the right-hand pane.
264
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-22 Capacity report - A23BLTZM Disk 0
IBM Tivoli Storage Resource Manager for Databases
Capacity Reporting for databases is very straightforward. You can report on:
򐂰 All databases of any type
򐂰 All databases of a given type on a particular system or group of systems
򐂰 On a specific database
Example 6-23 shows a Capacity Report by Computer Group. We actually have databases in
just one Computer Group, WindowsDBServers. We then drilled down to see all systems within
the WindowsDBServers group, then specifically to node GALLIUM, so that we could see all
databases on GALLIUM.
Chapter 6. Reporting
265
Figure 6-23 Database Capacity report by Computer Group
6.2.5 Usage Reporting
The reporting categories covered so far have been mostly concerned with reporting at the
system or device level. Usage Reporting goes down one more step to report at a level lower
than the filesystem. You can produce reports that answer questions such as:
򐂰 How old is my data? When was it created, last accessed, or modified?
򐂰 What are my largest files? What are my largest directories?
򐂰 Do I have any orphan files?
IBM Tivoli Storage Resource Manager
With Usage Reporting, you will be able to:
򐂰 Identify orphan files and either update their ownership or delete them to free up space
򐂰 Identify the largest files and determine whether they are needed or whether parts of the
data could be archived
򐂰 Identify obsolete files so that they can be either deleted or archived
There are a few restrictions on Usage Reporting:
򐂰 In order to report by directory or by Directory Group you will need to set them up in IBM
Tivoli SRM -> Monitoring -> Groups -> Directory
򐂰 UNIX systems do not record file create dates, so no reporting by creation time is available
for these systems.
IBM Tivoli Storage Resource Manager for Databases
Like database Asset Reporting, all of the database Usage Reporting options are quite
straightforward with the exception of table level reporting.
From a usage perspective there are two types of table report available:
򐂰 Largest tables
򐂰 Monitored tables
266
IBM Tivoli Storage Resource Manager: A Practical Introduction
We can report on database largest tables by choosing for example, Tivoli Storage Resource
Manager for Databases-> Reporting -> Usage -> All DBMSs -> Tables -> Largest Tables
-> By RDBMS Type. This report is shown in Figure 6-24.
Figure 6-24 Largest tables by RDBMS type
A Monitored Tables by RDBMS Type report is shown in Figure 6-25. In this case, only tables
which are part of a Table Group, which is included in a Scan job will be reported on.
Chapter 6. Reporting
267
Figure 6-25 Monitored tables by RDBMS type
6.2.6 Usage Violation Reporting
Usage Violation Reporting enforces Tivoli Storage Resource Manager Constraints and
Quotas. A Constraint is a limit, by file name syntax, on the type of data that can be stored on
a system. A Quota is a storage usage limit placed on a user or operating system User Group,
and can be defined at the network, computer, or filesystem level. Constraints and Quotas
were described in 5.3, “Policy management” on page 200. It is important to remember that
Quotas and Constraints are not hard limits - users will not be stopped from working if a Quota
or Constraint is violated, but this event will trigger an exception, which will be reported.
IBM Tivoli Storage Resource Manager Constraint Violation Reporting
There are a number of predefined Constraints in Tivoli Storage Resource Manager. Before
we produce a Constraint violation report, we need to set up a new Constraint called forbidden
files. Setting up Constraints was described in 5.3.4, “Constraints” on page 224.
First navigate Tivoli Storage Resource Manager -> Policy Management -> Constraints.
Existing Constraints will be listed. Right-click Constraints and choose New Constraint. On
the Filesystems tab we entered a description of forbidden files, chose Computer Groups,
then selected db2admin.Windows Systems and clicked >>. The completed Filesystems tab
is shown in Figure 6-26.
268
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-26 Create a Constraint - Filesystems tab
We then need to specify in the File Types tab, what a forbidden file is. You can define the
criteria as either inclusive or exclusive; that is, you can specify just those files types that will
violate the Constraint, or you can specify that all files will violate the Constraint except those
specified. There are a number of predefined file types included; you can also chose additional
files by entering appropriate values in the “Or enter a pattern field” at the bottom of the
form. We have chosen MP3 and AVI files. The completed File Types tab is shown in
Figure 6-27.
Chapter 6. Reporting
269
Figure 6-27 Create a Constraint - file types tab
The Users tab is very similar to the File Types tab - you can specify which users should be
included or excluded from the selection criteria. We have taken the default, which is to include
all users.
In the Options tab, we nominate a maximum number of rows to be returned. We can also
apply some more specific selection criteria here such as only including files that are larger
than a defined size. Note, however that these criteria are added to the file list. For example, if
we specified here that we only wanted to include files greater than 1 MB, the search criteria
would be changed to ((NAME matches any of ('*.AVI', '*.mp3') AND TYPE <> DIRECTORY)
OR SIZE > 1 MB). So the returned list of files would be any file greater than 1 MB in size plus
any *.MP3 or *.AVI files.
If you wish to change the selection criteria so that instead you select any *.MP3 or *.AVI files
that are larger than 1 MB, you can enter 1 MB against the bigger than option, and then click
the Edit Filter button shown in Figure 6-30. You will then see the file filter as shown in
Figure 6-28. To add the size criteria to the file type criteria, click on the Size > 1MB entry and
drag it up to the All of tag. The changed filter is shown in Figure 6-29. You can also see the
Boolean expression for the filter has changed to reflect this condition.
270
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-28 Edit a Constraint file filter - before change
Figure 6-29 Edit a Constraint file filter - after change
In this case we did not want to apply a size criteria, so we left the Option tab entries at their
defaults as shown in Figure 6-30.
Chapter 6. Reporting
271
Figure 6-30 Create a Constraint - Options tab
Finally, we can specify that we want an Alert generated if a triggering condition is met. The
only choice here is to specify a maximum amount of space consumed by the files that meet
our selection criteria. We left all of the Alert tab options at their defaults other than specifying
an upper limit of 100 MB for files that have met our selection criteria. The Alert tab is shown in
Figure 6-31. Alerting is covered in more detail in 5.2, “OS Alerts” on page 189.
We then clicked the Save button and entered a name of Forbidden Files as shown in
Figure 6-32.
272
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-31 Create a Constraint - Alert tab
Figure 6-32 Create a Constraint - save
Chapter 6. Reporting
273
Before we can report against the Constraint, we need to ensure that a Scan job has been run
to collect the appropriate information.
Once the Scan has completed successfully, you can go ahead and produce Constraint
Violation Reports. Note that you cannot produce a report of violations of a particular
Constraint - the report will include entries for any Constraint violation. However, once the
report is generated, you can drill down into specific Constraint violations.
We produced the report by choosing Tivoli Storage Resource Manager -> Reporting ->
Usage Violations -> Constraint Violation -> By Computer. You will see a screen like
Figure 6-33 where you can select a subset of the clients if appropriate - after selecting, click
Generate Report.
Figure 6-33 Constraint violation report selection screen
You will then see a list of all of those instances of Constraint violations as shown in
Figure 6-34.
The report shows multiple types of Constraints. Some of these Constraints were predefined
(Orphaned File Constraint and Obsolete File Constraint) and others (ALLFILES and forbidden
files) we defined. An orphaned file is any file that does not have an owner. This allows you to
easily identify files that belonged to users who have left your organization or have had an
incorrect ownership set.
274
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-34 Constraint violations by computer
From there you can drill down on a specific Constraint, then filesystems within the Constraint,
and finally to a list of files that violated the Constraint on that filesystem by selecting the
magnifying glass icon next to the entry of interest. Or, as shown in Figure 6-35, by clicking the
pie chart icon next to the entry for forbidden files, you can produce a graph indicating what
proportion of capacity is being utilized by files violating the Constraint. Position the cursor
over any segment of the pie chart to show the percentage and number of bytes consumed by
that segment. We can see that 13% or 7.7 Gigabytes of capacity is being consumed by files
violating the forbidden files Constraint on this filesystem.
Figure 6-35 Graph of capacity used by Constraint violating files
Chapter 6. Reporting
275
Constraint violations are also written to the Tivoli Storage Resource Manager Alert Log.
Figure 6-36 shows the same list of violations as if you had produced a Constraint Violations
by computer report.
Figure 6-36 Alert log showing Constraint violations
Quota Violation Reporting
The process of producing a Quota violation report is very similar to producing a Constraint
violation report, but with some key differences.
One difference between Quotas and Constraints is the process of collecting data. For
Constraints, the data is collected as part of a standard Scan job in a similar way to adding an
additional Profile to a Scan. Quota data collections are performed in a separately scheduled
job. So, when you set up a Quota you need to specify scheduling parameters.
We set up a Quota rule called Big Windows Users by choosing Tivoli Storage Resource
Manager -> Policy Management -> Quotas -> Users -> Computer, right-clicking Computer
and selecting New Quota. On the Users screen we entered a description of Big Windows
Users and then selected User Groups and then Tivoli.Default User Group as show in
Figure 6-37.
276
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-37 Create Quota - Users tab
On the Computers tab we chose our Windows group: db2admin.Windows Systems
(Figure 6-38).
Figure 6-38 Create Quota - Computers tab
Chapter 6. Reporting
277
We when had to specify when and how often we wanted the Quota job to run. We chose to
run the job weekly under the When to CHECK tab as shown in Figure 6-39.
Figure 6-39 Create Quota - When to Check
On the Alert tab, shown in Figure 6-40, we accepted all of the defaults other than to specify
the limit under User Consumes More Than, in this case, 1 GB.
No Alerts will be generated other than to log any exceptions in the Tivoli Storage Resource
Manager Alert Log.
278
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-40 Create Quota - Alert
Finally, we save the Quota definition, calling it Big Windows Users as shown in Figure 6-41.
Figure 6-41 Create Quota - save
Chapter 6. Reporting
279
The new Quota now appears under IBM Tivoli SRM -> Policy Management -> Quotas ->
Users > Computer as db2admin.Big Windows Users (where db2admin is our Tivoli Storage
Resource Manager username). We right-clicked the Quota and chose Run Now as in
Figure 6-42.
Figure 6-42 Run new Quota job
This job will collect data related to the Quota, and add any Quota Violations to the Alert Log
as shown in Figure 6-43.
Figure 6-43 Alert Log - Quota violations
280
IBM Tivoli Storage Resource Manager: A Practical Introduction
We then drilled down on one of the Alerts to see the details (Figure 6-44).
Figure 6-44 Alert Log - Quota violation detail
And finally we can create a Quota Violation report by choosing IBM Tivoli SRM -> Reporting
-> Usage Violations -> Quota Violations -> Computer Quotas -> By Computer. The
high-level report is shown in Figure 6-45.
Figure 6-45 Quota violations by computer
We can then drill down further for additional detail or to produce a graphical representation of
the data behind the violation. The graph in Figure 6-46 shows a breakdown of the users’ data
by file size.
Chapter 6. Reporting
281
Figure 6-46 Quota violation graphical breakdown by file size
IBM Tivoli Storage Resource Manager for Databases
Filesystem Usage Violation Reporting includes both Quota and Constraint violations.
However, for databases, only Quota violations are available.
You can place a Quota on users, user groups, or all users and you can limit the Quota by
computer, computer group, database instance, database tablespace group or tablespace.
We will set up an Instance Quota that limits any individual user to 100 MB of space per
instance for any database on any server in the db2admin.WindowsDBServers computer
group.
To do this, navigate to IBM Tivoli SRM for Databases -> Policy Management -> Quotas ->
Instance. Right-click Instance and choose New Quota. Figure 6-47 shows the Quota
definition screen. We entered a description of Big DB Users and selected the Tivoli.Default
User Group by expanding User Groups, clicking Tivoli.Default User Group, and then
clicking >>.

IBM Tivoli Storage Resource Manager: A Practical Introduction
6.2.7 Backup Reporting
Backup Reporting is designed to do two things: It can alert you to situations where files have
been modified but not backed up, and it can provide data on the volume of data that will be
backed up. Figure 6-55 shows the options that are available for Backup Reporting.
Figure 6-55 Backup Reporting options
Most at Risk Files
Tivoli Storage Resource Manager defines most at risk files as those that are least-recently
modified, but have not been backed up.
There are some points worth noting about this report:
򐂰 Since the report relies on the archive bit being set to determine whether the file has
changed, this report will only work on Windows systems as UNIX systems have no
equivalent to the archive bit
򐂰 When using most backup products, once a file has been backed up the archive bit is
cleared. Before Version 5.2, IBM Tivoli Storage Manager did not do this, therefore if this
level of Tivoli Storage Manager was used, this report would list files that actually may have
been backed up. IBM Tivoli Storage Manager Version 5.2 has the ability to reset the
Windows archive bit after a successful backup of a file. See “Backup reporting for Tivoli
Storage Manager V5.2” on page 295 for more information on the reset archive bit available
for the Tivoli Storage Manager Windows client.
By default, information on only 20 files will be returned. Figure 6-56 shows the selection
screen for the report. You will notice that the report uses the Profile Tivoli.Most at Risk. It is in
this Profile that the 20 file limit is set, although the value can be changed. You can override
the value on the selection screen, but you can only reduce the value here, not increase it.
By updating the Profile you can also exclude files from the report. By default, any file in the
\WINNT\system* directory tree on any device will be excluded. You can add entries to the
exclusion list if appropriate. Ideally, the exclusion list should be the same as that in your
backup product.
Chapter 6. Reporting
287
Figure 6-56 Files most at risk report - selection
Modified Files Not Backed up
The report provides an aging analysis of your data that has been modified but not backed up.
It will show what proportion of the data has been modified within the past 24 hours, between
one and seven days, between one week and one month, and so on. Figure 6-57 shows the
selection taken in our Windows environment. Like the Most at Risk Files report, this report
also relies on the archive bit, so check to see if your backup application uses this.
288
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-57 Modified Files not backed up selection
To view the report, click Generate report. We choose to view it as a graphic by then clicking
on the pie icon and selecting Chart: Space Distribution for All. This is shown in Figure 6-58.
This chart tells you the amount of space consumed by files have not been backed up since
the last backup was run for this server.
Figure 6-58 Modified Files not backed up chart overall view
Chapter 6. Reporting
289
We can also select Chart: Count Distribution for All as shown in Figure 6-59 to show the
number of files in each category.
Figure 6-59 Files need backed up chart in detail view
The different charts can be viewed in different ways. To select another type of chart, right-click
in the chart area and select another type - e.g. bar chart, as shown in Figure 6-60.
Figure 6-60 Files not backed up bar chart detail view
290
IBM Tivoli Storage Resource Manager: A Practical Introduction
Backup Storage Requirements Reporting
This option allows you determine how much data would be backed up if you were to perform
either a full or an incremental backup. The Full Backup Size option can be used regardless of
the OS type and the backup application in use.
In Figure 6-61, the report is run against Windows systems by filesystem.
Figure 6-61 Backup storage requirements per filesystem
The selection can also run by computer, as shown in Figure 6-62.
Chapter 6. Reporting
291
Figure 6-62 Backup storage requirement per computer and per filesystem
The Incremental Backup Size option makes use of the archive bit, so it can only be used on
Windows systems, and if Tivoli Storage Manager is the backup application, the
resetarchiveattribute option must be used (for Version 5.2). A sample report is shown in
Figure 6-63.
292
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-63 Incremental reporting per Node and Filesystem based on files
The third report type here is Incremental Range Sizes Reporting. This does not rely on the
archive bit (instead, it uses the modification date) so is more generically applicable. It is
possible to show through the use of this report the actual difference between a traditional
weekly full/daily incremental backup process versus Tivoli Storage Manager’s progressive
incremental approach. To generate this report, select Backup -> Backup Storage
Requirements -> Incremental Range Size -> By Computer as shown in Figure 6-64.
Chapter 6. Reporting
293
Figure 6-64 Incremental Range Size select By Computer
After you select the Computers of interest, click Generate Report. Figure 6-65 shows the
output from this report, with the amount of data changed for different time ranges. Note that
the values are cumulative, so for each time range; the values shown include the smaller time
periods.
If we take the results for system BONNIE as an example, it shows that 390 files (1.02% of all
files) and 41.66 MB (1.82% of total storage) changed within the previous 24 hours and 2831
files (7.45% of all files) and 2.33 GB (53.42% of total storage) changed within the last week.
Using the report for IBM Tivoli Storage Manager planning
Tivoli Storage Manager’s progressive incremental capability avoids the necessity of
performing regular full backups by keeping a record in its own relational database of what files
have been backed up, and then only backing up those files that have changed.
A typical metric when doing Tivoli Storage Manager planning is to estimate the amount of
data that changes each day in a file server environment as typically about 5-10%. With Tivoli
Storage Resource Manager, we can replace this estimate with actual numbers.
The 1.02% change rate here is outside the typical range because the system is in a lab
environment, and is not performing production work. But, to demonstrate the calculations we
will use those figures.
294
IBM Tivoli Storage Resource Manager: A Practical Introduction
If we assume that 1.02% is the average for each day, that gives a weekly change rate of
7.14%. Seven times the daily rate of change will almost always be greater than the reported
weekly change rate as some files will be updated on multiple days throughout the week.
With Tivoli Storage Manager’s progressive incremental approach in this example we will only
backup approximately 291.62 MB (7 * 41.66 GB) per week compared to 4738 MB (4.38 GB *
1024 = 4485 MB + (6 * 41.66 MB)) for a traditional weekly full plus daily incremental
approach.

Backup reporting for Tivoli Storage Manager V5.2
With IBM Tivoli Storage Manager Version 5.2 and IBM Tivoli Storage Resource Manager
V1.2, we have now the possibility to get more accurate statistics than in previous IBM Tivoli
Storage Resource Manager Versions.
To set this up we use a new option, resetarchiveattribute, in the DSM.OPT file for Windows
clients, as shown in Example 6-2. The use of this option determines whether Tivoli Storage
Manager resets the Windows archive attribute on files that have been successfully backed up
to a Tivoli Storage Manager server. Tivoli Storage Manager will also reset the archive attribute
during incremental backups if it is determined that there is already an active object on the
Tivoli Storage Manager server. The resetarchiveattribute option is useful in conjunction
with applications, such as IBM Tivoli Storage Resource Manager, as a simple way to report
on the backup status of files.
The Windows archive attribute is used to indicate that a file has changed since the last
backup. If it has been set to OFF, the Windows operating system will turn the attribute back to
ON after the file has been modified. Tivoli Storage Manager does not use the Windows archive

attribute to determine if a file is a candidate for incremental backup, (it uses its own algorithms
to determine this) but only for the purposes of reporting.

You can also use the Tivoli Storage Manager Preferences editor, as shown in Figure 6-66 to

client (including the Windows Scheduler Service) to make the changes active.

Figure 6-67 ESS Reporting capabilities
The reporting capabilities in Tivoli Storage Resource Manager are expanded in Version 1.2 to
include Enterprise Storage Subsystem (ESS) reporting. IBM Tivoli Storage Resource
Manager uses Probe jobs to collect information about the ESS. We can then use the
reporting facility to view that information. The new subsystem reports show the capacity,
controllers, disks, and LUNs of an ESS and their relationships to computers and filesystems
within a network. Figure 6-67 summarizes the functionality.
6.3.1 ESS Reporting
For this section we discuss ESS asset and storage subsystem reporting, making refererences
to the ESS lab environment in Figure 6-68 below. Note that the host which accesses the ESS
had a Tivoli Storage Resource Manager Agent installed. This provides the fullest combination
of reporting ability for the ESS. If an ESS-attached host does not have a Tivoli Storage
Resource Manager Agent installed, items such as filesystem, logical volume, and device
logical names will not be displayed.

Prerequisites to ESS reporting
Before doing ESS reporting with Tivoli Storage Resource Manager, the following are required:
򐂰 CIM/OM server successfully installed.
򐂰 IBM Tivoli Storage Resource Manager successfully logs into CIM/OM server.
򐂰 IBM Tivoli Storage Resource Manager successfully runs a discovery and probes the ESS.
Important: Refer to 4.9, “CIM/OM” on page 145 for additional details on confirming
these prerequisites.
The IBM Tivoli Storage Resource Manager will run a discovery to locate the CIM/OM server
in our environment, which in turn discovers the ESSs. See 4.9.3, “CIM/OM configuration in
IBM Tivoli Storage Resource Manager” on page 153.
Creating the ESS Probe
IBM Tivoli Storage Resource Manager will then run a Probe to query the discovered ESS.
The Probe collects detailed statistics about the storage assets in our enterprise, such as
computers, storage subsystems, disk controllers, hard disks, and filesystems.
Next, we show how to create a Probe for an ESS-F20. Select Probe -> Select new probe,
then under the Computers tab, choose Storage Subsystems. See Figure 6-69.
298
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-69 Creating ESS probe
On the When to PROBE tab, we selected PROBE Now because we need to populate the
backend repository. See Figure 6-70.
Figure 6-70 ESS - When to probe
Chapter 6. Reporting
299
Next is the Alert tab, shown in Figure 6-71. This defines the type of notification for a Probe.
Figure 6-71 ESS - Alert tab
After all parameters are defined, save the Probe definition. At this point the Probe is
submitted and will run immediately.
Note: For additional information on creating Probes, see 5.1.5, “Probes” on page 177.
There are several ways to check the status of the Probe job. First, we can check the color of
the Probe job entry in the navigation tree, then in the content panel. There are two colors that
represent job status. They are:
򐂰 GREEN - Job successfully complete with no errors
򐂰 RED - Job completed with errors
The status of the Probe job is displayed in text and in color, as shown in Figure 6-72, after
selecting the Probe job output in the navigation tree. The job at 8:44 am is in green, indicating
success. The job at 6:32 pm is in red, indicating errors.
300
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-72 ESS - probe job status
We open the Probe job by selecting it and double clicking on the spy glass icon next to the
job in the content window. We see the contents of the job, including detailed information on
the status, as in Figure 6-73. Here, we have selected the successful Probe on June 9 at 8:44.
Figure 6-73 Probe job log
Asset Reports - By Storage Subsystem
With Asset reporting by storage subsystem, you can view the centralized asset repository that
IBM Tivoli Storage Resource Manager constructs during a Probe. The Probe itemizes the
information about computers, disks, controllers, and filesystems, and builds a hardware
inventory of ESS assets. With the backend repository now populated with ESS-F20 asset
information, we will show how to view reports to display the storage resources.
We choose Reporting -> Asset -> By Storage Subsystem -> ESSF20. This report provides
specific resource information of the ESS and allows us to view storage capacity by a
computer, filesystem, storage subsystem, LUN, and disk level. We can also view the
relationships between the components of a storage subsystem. Notice that the navigation
tree is hierarchical, and shows ESSF20 as active (green). See Figure 6-74.
Chapter 6. Reporting
301
Figure 6-74 Asset by storage subsystem
We drill down to the Disk Groups. The disk group contains information related to the ESS, as
well as the volume spaces and disks associated with those Disk Groups. Expanding the Disk
Group node, a list of all Disk Groups on the ESS displays (Figure 6-75).
Figure 6-75 ESS disk group
Continuing, we expand the disk group DG1 to view the disks and volume spaces within it. We
open Volume Space VS3, which shows the disks and LUNs associated with it. The Disks
subsection shows the individual disks associated with the Volume Space (see Figure 6-76).

Figure 6-76 Disks in volume spaces
Notice the LUNs subsection for disk DD0105 (Figure 6-77). This shows the LUN to disk
relationship. The LUNs shown here are just a subset of all the LUNs. You can see that the
LUN is spread across all the displayed disks in the content window.

Note that on BONNIE’s C drive we found 13 files.
4. Define new Constraint
We would like to know where specifically these files are located. To set up this search,
select IBM Tivoli SRM -> Policy Management -> Constraints -> Tivoli.Orphaned File
Constraint, as shown in Figure 6-136. Enter a description, and select the Filesystem
Groups and Computers where you want to locate the files.

Select the Options tab, then select Edit Filter as shown in Figure 6-137.
Figure 6-137 Update the Orphaned selection
On the Edit Filter pop-up, double click the ATTRIBUTES Filter. Here we will replace the
ORPHANED condition with our own filter, since we want to actually search for Tivoli
Storage Manager option files, not orphaned files (Figure 6-138).

Use the Del button to delete the ORPHANED condition, then select NAME from the
Attributes pull-down, and the Add button to add another Attributes condition. We will
specify to search for Tivoli Storage Manager option files (including with an .smp extension
for sample files), as in Figure 6-139.
Figure 6-139 Enter the file search criteria
After each file pattern entry, click Add to save it. When all search arguments are entered,
click OK to save the search. The selection is now complete as in Figure 6-139.

341
Figure 6-140 File Filter selection reconfirm
Click OK again. Save the search with a new description and name (File -> Save As), so
that you do not overwrite the original Tivoli.Orphaned File Constraint. We called the
search “TSM Option File search.”
Now we have to embed the new Constraint into our Scan.
5. Bind the new Constraint into your Scan
To create or add this entry, go to IBM Tivoli SRM -> Monitoring -> Scans ->
Tivoli.Default.Scan. In the Profiles tab, add administrator.TSM Opt File search to the
right hand panel as in Figure 6-141. This will bind the Tivoli Storage Manager Option file
search to the filesystem search.
Figure 6-141 bind the Orphan search into Profiles to apply to Filesystems column
Finally, save and run the Scan. Check the Scan Job log for correct execution, as shown in
Figure 6-142.

6.5 Creating customized reports
Customized Reporting within Tivoli Storage Resource Manager is done through the My
Reports option, which is available for both Tivoli Storage Resource Manager and Tivoli
Storage Resource Manager for Databases.
There are three main options available within My Reports:
򐂰 System Reports
򐂰 Reports owned by username
򐂰 Batch Reports
System Reports, while included here in the customized reporting section, is in fact not
customizable currently. We will still discuss it in this section as it is part of the My Reports
group.
Reports owned by username’s Reports, where username is the currently logged in Tivoli
Storage Resource Manager username, are modified versions of standard reports from the
Reporting option. You will only see reports here that you have modified and saved.
Batch Reports are reports that are typically set up to run on a schedule, although they can be
run interactively. The key difference between Batch Reports and other reporting options is
that with Batch Reports, the output will always be written to an output file rather than
displayed on the screen.
6.5.1 System Reports
These reports can, at this point in time at least, only be run as is. You cannot modify the
parameters in any way, nor can you add additional reports to the list.
Chapter 6. Reporting
345
These reports provide the same information than is available from running reports from the
Reporting option. The intent of these reports is to provide frequently needed information,
which can be provided quickly and repetitively without having to reenter parameters.
IBM Tivoli Storage Resource Manager
Figure 6-147 shows the available System Reports for Tivoli Storage Resource Manager.
Figure 6-147 My Reports - System Reports
Figure 6-148 shows the output from running the Storage Capacity system report. We could
have generated exactly the same output by selecting IBM Tivoli SRM -> Reporting ->
Capacity -> Disk Capacity -> By Computer -> Generate Report. Obviously, selecting IBM
Tivoli SRM -> My Reports -> Storage Capacity is a lot simpler.
346
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-148 My Reports - Storage Capacity
IBM Tivoli Storage Resource Manager for Databases
The System Reports available for Tivoli Storage Resource Manager for Databases are shown
in Figure 6-149. While there are quite a few reports available, they fall into three main
categories:
򐂰 Database storage by database
򐂰 Database storage by user
򐂰 Database freespace
The only report that does not fall into one of those categories is a usage violation report.
Figure 6-149 shows the output from the All Dbms - User Database Space Usage report. We
are not so much interested in the report contents as such here, but rather in the fact that when
the report was run it produced a report for all users. You can go back to the selection tab and
select specific users if required. This capability exists for all of the System Reports.
Chapter 6. Reporting
347
Figure 6-149 Available System Reports for databases
6.5.2 Reports owned by a specific username
In concept this option is very similar to System Reports. You can include here those reports
that you need to run regularly, consistently and easily. The difference, compared to System
Reports, is that you get to decide what reports are included and what they look like.
However, it is important to remember that you will only see those reports that have been
created by the currently logged in Tivoli Storage Resource Manager username.
IBM Tivoli Storage Resource Manager
We will define a report here for db2admin, the username that we are currently logged in as.
We will create a report that is exactly the same as the Storage Capacity system report as
shown in Figure 6-148. In practice this is not something you would normally do as a report
already exists. However, this will demonstrate more clearly how the options relate to each
other.
We select IBM Tivoli SRM -> Reporting -> Capacity -> Disk Capacity -> By Computer ->
Generate Report. Once the report is produced, we save the report definition, using the name
My Storage Capacity. This is shown in Figure 6-150.
348
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-150 Create My Storage Capacity report
Once the report is saved you will see it available under username’s Reports for db2admin as
shown in Figure 6-151.
There are a few features of saved reports worth mentioning here. Firstly, characteristics such
as sort order are not saved with the report definition; however, selection criteria are saved.
Secondly, you can override the selection criteria when running your report. By default the
objects selected at the time of the save only will be reported. However, you can use the
Selection tab when running the saved report to include or exclude objects from the report. If
you change selection criteria you can resave the report, or save it under another name to
update the definition or create a new definition respectively.
Chapter 6. Reporting
349
Figure 6-151 My Storage Report saved
IBM Tivoli Storage Resource Manager for Databases
Database Reports created for specific users, in this case db2admin, are set up the same as in
Tivoli Storage Resource Manager.
We will show one brief example here. We will take one of the reports that we created earlier in
our discussion on Reporting (in this case Figure 6-25 on page 268) the Monitored Tables by
RDBMS Type report and set it up to be able to run more easily.
First we run the report by choosing IBM Tivoli SRM for Databases -> Reporting -> Usage
-> All DBMSs -> Tables -> Monitored Tables -> By RDBMS Type. We then saved the report
definition, naming it Monitored Tables by RDBMS Type. This is shown in Figure 6-152.
350
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-152 Monitored Tables by RDBMS Types customized report
The report is more easily run now by choosing IBM Tivoli SRM for Databases -> My
Reports -> username’s Reports -> Monitored Tables by RDBMS Type.
6.5.3 Batch Reports
In this section we will show how we set up some Batch Reports. All of the reports were set up
in the same way so we will use only one as an example. The process is the same whether the
report is for Tivoli Storage Resource Manager or Tivoli Storage Resource Manager for
Databases.
IBM Tivoli Storage Resource Manager
To set up a new report right-click on Batch Reports and select New Batch Report. You will
then see the screen shown in Figure 6-153.
Chapter 6. Reporting
351
Figure 6-153 Create a Batch Report
Now, it is a simply a matter of specifying what has to be reported, plus when and what the
output should be. In this case we are going to create a system uptime report. As shown in
Figure 6-154, we entered our report description of System Uptime and have then selected
Availability ->Computer Uptime ->By Computer and clicked >>. Our selection is then
moved into the right hand panel, Current Selections.
Figure 6-154 Create a Batch Report - report selection
We then selected the Selection tab, which is shown in Figure 6-155. Here we are able to
select a subset of available data by either reporting for a specified time range or a subset of
available systems. We took the defaults here.
352
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-155 Create a Batch Report - selection
On the Options tab, we specified that the report should be executed and generated on the
Agent called LOCHNESS, which is our Tivoli Storage Resource Manager server. We selected
HTML for Report Type Specification and then changed the rules for the naming of the
output file under Output File Specification.
By default the name will be {Report creator}.{Report name}.{Report run number}. In this
case we do not really care who created the report and having a variable like report run
number, which changes every time a new version of the report is created and makes it difficult
to access the file from a static Web page. So we changed the report name to be {Report
name}.html.
The report will be created in <install-directory>Tivoli Storage Resource Manager\log\Tivoli
Storage Resource Manager-agent-name\reports on the Agent system where the report job is
executed. There is no ability to override the directory name. For example, c:\program
files\tivoli\tsrm\log\lochness\reports on our Windows 2000 Tivoli Storage Resource Manager
server LOCHNESS or /usr/tivoli/tsrm/log/brazil/reports on our AIX Tivoli Storage Resource
Manager Agent BRAZIL.
The Option tab is shown in Figure 6-156.
Note here that it possible to run a script after the report is created to perform some type of
post-processing. For example, you might need to copy the output file to another system if your
Web server is on a system that is not running an Tivoli Storage Resource Manager Agent.
Chapter 6. Reporting
353
Figure 6-156 Create a Batch Report - options
On the When to REPORT tab we specified when the report should be generated. We chose
REPORT Repeatedly and then selected a time early in the morning (3:15 AM) and specified
that the report should be generated every day. This is shown in Figure 6-157.
354
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-157 Create a Batch Report - when to report
We left the Alert tab options as default, but it is possible to generate an Alert through several
mechanisms including e-mail, an SNMP trap, or the Windows event log should the generation
of the report fail.
Finally, we saved the report, calling it System Uptime, as shown in Figure 6-158.

We will use the same example here as we used in 6.5.2, “Reports owned by a specific
username” on page 348, that is a Monitored Tables by RDBMS Type, but here we will save it
in HTML format.
We choose IBM Tivoli SRM for Databases -> My Reports -> Batch Reports, right-click
Batch Reports and select New Batch Report as shown in Figure 6-159.
356
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-159 Create a database Batch Report
Figure 6-160 shows the Report tab. We expanded in turn Usage -> All DBMSs -> Tables ->
Monitored Tables -> By RDBMS Type and clicked >>. We also entered a Description of
Monitored Tables by RDBMS Type.
Figure 6-160 Create a database Batch Report - Report tab
We accepted the defaults on the Selection tab, which is to report on all RDBMS types and
then went to the Options tab, shown in Figure 6-161. We set the Agent computer, which will
run the report to GALLIUM.
Note that the system that you run the report on must be licensed for each type of database
that you are reporting on. If we were to run the report on LOCHNESS, the Tivoli Storage
Chapter 6. Reporting
357
Resource Manager server system, we would need to have the Tivoli Storage Resource
Manager for Databases licences for Oracle and SQL-Server licences loaded there even
though LOCHNESS does not run these databases.
We also set the report type to HTML and changed the output file name to be {Report
name}.html. This is shown in Figure 6-161.
Figure 6-161 Create a database Batch Report - Options tab
On the When to Report tab, shown in Figure 6-162, we chose REPORT Repeatedly and set
a start time.
358
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-162 Create a database Batch Report - When to Report tab
We did not change anything in the Alert tab. We saved the definition with the name Monitored
Tables by RDBMS Type as shown in Figure 6-163.
Figure 6-163 Create a database Batch Report - save definition
We can now run the report by choosing IBM Tivoli SRM -> My Reports-> Batch Reports
and then right-clicking on db2admin.Monitored Tables by RDBMS Type and choosing Run
Now.
Figure 6-164 shows the output from the report execution.
Chapter 6. Reporting
359
Figure 6-164 Monitored Tables by RDBMS Type batch report output
6.6 Setting up a schedule for daily reports
Tivoli Storage Resource Manager can produce reports according to a schedule. In our lab
environment, we set up a number of Batch Reports as shown in Figure 6-165. Note that the
name of each of the reports is prefixed by db2admin. This is the Windows username that we
used to log into Tivoli Storage Resource Manager. Even though the reports were created by a
particular user, other Tivoli Storage Resource Manager administrative users still have access
to the reports (Tivoli Storage Resource Manager non-administrative users can only look at
the results).
It is possible to generate output from Batch Reports in various formats including HTML,CSV,
(comma separated values) and formatted reports. For all of the reports that we set up, we
specified HTML as the output type, and also set them to run on a daily schedule. That way it
is very easy to use a browser to quickly look at the state of the organization’s storage. It also
means that anyone can look at the reported data through their browser, without having
access to, or indeed, knowing how to use Tivoli Storage Resource Manager. Obviously, if
unrestricted access to this data was not desirable some sort of password based security
could be included within the Web page.
Currently, all of the HTML output from Batch Reports is in table format - graphs cannot be
produced. There is also no ability to affect the layout of the reports in terms of sort order,
nominating the columns to be displayed or the column size. Using the interactive reporting
capability of the product does allow graphs to be produced and gives you some additional
capability in determining what the output looks like. To go further than that you can export to a
CSV file, and then use a tool such as Lotus 1-2-3® or Microsoft Excel to manipulate the
output.
The next section shows how to develop the Web site.
360
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 6-165 Batch Reports listing
6.7 Setting up a reports Web site
Since Tivoli Storage Resource Manager can easily generate reports in HTML format, it is a
logical extension to set up a Web site where the reports can be easily viewed.
Since Tivoli Storage Resource Manager itself is easy to install and use, we likewise took a
fairly simplistic view to creating the Web site. We used the Microsoft Word Web Page Wizard
to create the basic layout of the page as shown in Figure 6-166.
The main page has two frames. In the left hand frame we have created links to each of the
report files. The right hand frame is where the reports are displayed.
As additional Batch Reports are needed, it is a relatively simple process of editing the HTML
source and including another hot link.
Obviously, this could be made more sophisticated. An example would be to have the browser
list all HTML files within the report directory.
Chapter 6. Reporting
361
Figure 6-166 MS Word created Web page
We then used the Virtual Directory Creation Wizard within Microsoft Internet Information
Server (IIS) to set up access to the reports as shown in Figure 6-167.
362

6.8 Charging for storage usage
Through the optional IBM Tivoli Storage Resource Manager for Chargeback product, IBM
Tivoli Storage Resource Manager provides the ability to produce Chargeback information for
storage usage. The following items can have charges allocated against them:
򐂰
򐂰
򐂰
򐂰
Operating system storage by user
Operating system disk capacity by computer
Storage usage by database user
Total size by database-tablespace
For each of the Chargeback by user options, a Profile needs to be specified. Profiles are
covered in 5.1.6, “Profiles” on page 180.
IBM Tivoli Storage Resource Manager can directly produce an invoice or create a file in CIMS
format. CIMS is a set of resource accounting tools that allow you to track, manage, allocate,
and charge for IT resources and costs. For more information on CIMS see:
http://www.cims.com.
Figure 6-169 shows the Parameter Definition screen. The costs allocated here do not
represent any real environment, but represent an example, based on these assumptions:
򐂰
򐂰
򐂰
򐂰
364
Disk hardware costs, including controllers and switches. is $0.50 per MB
Hardware costs are only 20% of the total cost over the life of the storage = $2.50 /MB
On average only 50% of the capacity is used = $5.00 /MB used
The expected life of the storage is 4 years - $5.00 /48 = 0.1042 /MB /month
IBM Tivoli Storage Resource Manager: A Practical Introduction
򐂰 The figures used are for monthly Chargeback
򐂰 Chargeback is for cost recovery only, no profit
Figure 6-169 Chargeback parameter definition
In this example we have chosen to perform Chargeback by computer. It is possible to
separately charge for database usage and use a different rate from the computer rate. To do
this you would need to set up a Profile that excluded the database data, otherwise, it would be
counted twice.
Chargeback is useful, even if you do not actually collect revenue from your users for the
resources consumes. It is a very powerful tool for raising the awareness within the
organization of the cost of storage, and the need to have the appropriate tools and processes
in place to manage storage effectively and efficiently.
Figure 6-170 shows the Chargeback Report being created. Currently, it is not possible to have
the Chargeback Report created automatically (that is, scheduled).

Figure 7-1 Tivoli Storage Resource Manager components
Tivoli Storage Resource Manager relies on two main components: a Server and one or more
Agents. Each of them stores configuration data in text files and/or in databases. We describe
now each component and explain where they store their configuration information.
7.1.1 IBM Tivoli Storage Resource Manager Server
The Tivoli Storage Resource Manager Server stores its configuration:
򐂰 In flat files in the directories (for Windows platforms - similar for UNIX):
– \Program Files\tivoli\tsrm\config\
– \Program Files\tivoli\tsrm\scripts\
򐂰 In a DB2, SQL-Server, Oracle, Sybase, or Cloudscape database
The configuration files contain information including the TCP/IP ports to be used by the
Server and Agents, database name, and username.
The Tivoli Storage Resource Manager database contains information about the configured
Agents, policies, schedules, and the actual storage resource data.
Our Tivoli Storage Resource Manager database is called ITSRMDB.

7.2.1 IBM Tivoli Storage Manager
IBM Tivoli Storage Manager is an enterprise-wide storage management application for the
network. It provides automated storage management services (including backup and restore,
archive and retrieve, hierarchical space management and Disaster Recovery) to multi-vendor
workstations, personal computers, mobile laptops, and servers of all sizes and operating
systems, which are connected through WAN, LAN, and SAN. IBM Tivoli Storage Manager
includes these components:
򐂰 Server - The repository for all backups and maintains the backup policies and schedules
򐂰 Clients - Backup data to the Tivoli Storage Manager Server
򐂰 API - Available to allow other applications to interface to Tivoli Storage Manager
Chapter 7. Protecting and maintaining Tivoli Storage Resource Manager

IBM Tivoli Storage Manager for Databases
IBM Tivoli Storage Manager for ERP
IBM Tivoli Storage Manager for Application Servers

Each of these products provide the interface between the IBM Tivoli Storage Manager API
and an application or database API.
The Tivoli Storage Manager Web site is:
http://www-3.ibm.com/software/tivoli/products/storage-mgr/
IBM DB2/UDB databases can be backed up to IBM Tivoli Storage Manager as DB2/UDB has
built in IBM Tivoli Storage Manager API support.
Normal flat files (configuration, log and report files) on the Tivoli Storage Resource Manager
Server can be backed up using the IBM Tivoli Storage Manager Backup/Archive client.
Therefore, the two client types (Backup/Archive client for flat files, API client for DB2 backup)
work together to provide full data protection for your Tivoli Storage Resource Manager
environment.
The DB2/UDB API client and the IBM Tivoli Storage Manager Backup/Archive client can run
simultaneously on the same DB2 server, however, they are totally separate clients as far as
the Tivoli Storage Manager server is concerned and we will configure them separately.
7.2.2 Setup for backing up Tivoli Storage Resource Manager
We will use the following environment for backing up our Tivoli Storage Resource Manager
Server to a Tivoli Storage Manager Server:
򐂰 Tivoli Storage Manager Server for AIX, V5.2.0.0, running on BANDA
򐂰 Tivoli Storage Manager Backup/Archive client for Windows 2000, V5.2.0.0 running on the
Tivoli Storage Resource Manager Server BONNIE
򐂰 Tivoli Storage Manager DB2/UDB API client for Windows 2000, V5.2.0.0 running on the
Tivoli Storage Resource Manager Server BONNIE
򐂰 Tivoli Storage Manager Backup/Archive client for LINUX, V5.2.0.0 running on the Tivoli
Storage Resource Manager Agent SUSE82-1.

Figure 7-3 Backup environment tor Tivoli Storage Resource Manager
The summary of the setup steps is:
1. Configure the Tivoli Storage Manager Server to receive backups from the Tivoli Storage
Resource Manager Server.
2. Configure the DB2/UDB API and Tivoli Storage Manager Backup/Archive clients on the
Tivoli Storage Resource Manager Server.
7.2.3 Tivoli Storage Manager Server configuration
We assume that:
򐂰 The Tivoli Storage Manager Server is installed and configured with sufficient storage.
򐂰 The Tivoli Storage Manager Backup/Archive and API code is installed on the Tivoli
Storage Resource Manager Server.
򐂰 Appropriate backup policies (policy domain, management classes, copy groups) for
non-DB2 backups (that is, flat files) have been implemented. You should be doing OS-level
backups of the Windows 2000 Server, which runs the Tivoli Storage Resource Manager
code.
We need to specify a management class and copy group within a policy domain for DB2
backups. We recommend defining a separate policy domain for the DB2 backups. We will
define a domain called DB2_DOMAIN and register the nodename assigned to the DB2
backup client (in our case, BONNIE_DB2) to it.
DB2 places special requirements on the management class. Each DB2 database backup is
stored as a unique object in the Tivoli Storage Manager Server, by specifying a time stamp as
Chapter 7. Protecting and maintaining Tivoli Storage Resource Manager
373
part of the low-level qualifier (LL_NAME). This means that the DB2 backups must be
manually deactivated. This also means that the management class that the backup objects
are bound to should have retention settings that change the deactivated backup objects to be
expired immediately. The retention settings for a backup copy group that would provide this is
RETONLY=0 and VERDELETED=0.
Example 7-1 shows typical Tivoli Storage Manager commands to define an adequate
environment for DB2 backups. We define a policy domain, policy set, management class, and
copy groups for the DB2 environment. We activate the policy set and register our client node
to the policy domain. We are using a storage pool called BACK_LTO as the destination for our
DB2 backups.
Example 7-1 Tivoli Storage Manager setup for Tivoli Storage Resource Manager DB2 backups
DEFINE DOMAIN DB2_DOMAIN DESCRIPTION="Domain for DB2 backups" BACKRETENTION=30
ARCHRETENTION=365
DEFINE POLICYSET DB2_DOMAIN DB2_POLICY DESCRIPTION="DB2 BACKUPS Policyset"
DEFINE MGMTCLASS DB2_DOMAIN DB2_POLICY DB2_MGMTCLASS DESCRIPTION="Mgmtclass for DB2
databases" SPACEMGTECHNIQUE=NONE AUTOMIGNONUSE=0 MIGREQUIRESBKUP=YES
DEFINE COPYGROUP DB2_DOMAIN DB2_POLICY DB2_MGMTCLASS DESTINATION=BACK_LTO FREQUENCY=0
VEREXISTS=1 VERDELETED=0 RETEXTRA=0 RETONLY=0 MODE=MODIFIED SERIALIZATION=SHRSTATIC
DEFINE COPYGROUP DB2_DOMAIN DB2_POLICY DB2_MGMTCLASS TYPE=ARCHIVE DESTINATION=ARCHIVEPOOL
RETVER=NOLIMIT SERIALIZATION=SHRSTATIC
ASSIGN DEFMGMTCLASS DB2_DOMAIN DB2_POLICY DB2_MGMTCLASS
ACTIVATE POLICYSET DB2_DOMAIN DB2_POLICY
REGISTER NODE BONNIE_DB2 BONNIEDB2 DOMAIN=DB2_DOMAIN ARCHDELETE=YES BACKDELETE=YES
USERID=NONE
The following parameters for the backup copy group were set:
򐂰 VEREXISTS=1 to keep only one version of the backup file as the name of each DB2
backup is unique. (There will never be a newer version of the backup image with the same
name.)
򐂰 VERDELETED=0 so that if the backup file has been deleted (through db2adutl), then
Tivoli Storage Manager should not keep an inactive version of this file.
򐂰 RETEXTRA=0 (the same value as RETONLY) parameter will never be used as you will
never have more than one version of the backup file. To prevent confusion set this
parameter to the same value as RETONLY.
򐂰 RETONLY=0 so that when a backup image file becomes inactive it will be purged from the
Tivoli Storage Manager Server at the next expiration.
7.2.4 Client configuration
The client configuration takes place on BONNIE, the Tivoli Storage Resource Manager
Server, since this will be the Tivoli Storage Manager client. For Tivoli Storage Resource
Manager Agents, you should perform regular backups using the Tivoli Storage Manager
Backup/Archive client. No special considerations for Tivoli Storage Resource Manager should
be necessary. We will focus primarily on the setup for backing up the DB2 repository.
374
IBM Tivoli Storage Resource Manager: A Practical Introduction
Tivoli Storage Manager nodenames
The Tivoli Storage Resource Manager Server will use two different Tivoli Storage Manager
client names, for DB2 and non-DB2 backups. We will assume the client named BONNIE (for
the Tivoli Storage Manager Backup/Archive client) is already defined to the STANDARD
policy domain. The client name BONNIE_DB2 will be used for DB2 backups, which was
defined to the Tivoli Storage Manager Server in Example 7-1. Figure 7-2 shows the server
QUERY NODE command to display currently configured clients.
Example 7-2 Tivoli Storage Manager clients list

DB2 configuration
Now, you must configure DB2 so that it uses the correct Tivoli Storage Manager node name,
password, and management class.
This can be done in two different ways. Either you define these parameters within DB2 as
shown in Example 7-4, or you can rely on information taken from the Tivoli Storage Manager
client options file, in association with the default Tivoli Storage Manager settings defined in
7.2.3, “Tivoli Storage Manager Server configuration” on page 373.
In both cases you will need to set some OS environment variables so that the Tivoli Storage
Manager API is able to find the Tivoli Storage Manager options file and knows where to write
log files. These environment variables are shown in Example 7-3.
Tip: We used a different DSM.OPT (DB2_DSM.OPT) file to save our DB2 environment. To
“inform” our DB2 environment, you have to define all the DSMI_ variables to the system. If
you should choose this simple way, you do not have to add the Tivoli Storage Manager
entries into the DB2 configuration of the database ITSRMDB as shown in Example 7-4,
TSM_MGMTCLASS, TSM_NODENAME, TSM_OWNER, TSM_PASSWORD. If you have
these entries in the DB2 configuration, you can remove them with the following commands:
update db cfg for ITSRMDB using TSM_MGMTCLASS ‘’
update db cfg for ITSRMDB using TSM_OWNER ‘’
update db cfg for ITSRMDB using TSM_NODENAME ‘’
update db cfg for ITSRMDB using TSM_PASSWORD ‘’
Otherwise, define them into the system variables as shown in Example 7-3.
Example 7-3 IBM Tivoli Storage Manager environment variables for API client
DSMI_CONFIG=c:\tivoli\tsm\api\db2_dsm.opt
DSMI_DIR=c:\tivoli\tsm\api
DSMI_LOG=c:\tivoli\tsm\api
Chapter 7. Protecting and maintaining Tivoli Storage Resource Manager
375
There are four Tivoli Storage Manager parameters that can be defined within DB2:
򐂰
򐂰
򐂰
򐂰
Management class
Owner
Nodename
Password
Example 7-4 shows the setup of these parameters, however, our recommendation is not to
set any of these parameters, but to rely on the Tivoli Storage Manager options file and default
settings. If you rely on the Tivoli Storage Manager options file and default settings, then for the
above four settings: the management class should be the default management class for the
node, the owner is not required to be set, the nodename comes from the Tivoli Storage
Manager options file and the password, when used with the Tivoli Storage Manager options
file setting passwordaccess generate, is stored in encrypted form in the Windows registry or
in a file on UNIX platforms.
Being able to set these options within DB2 does offer some flexibility when you have multiple
databases on the one system, which has different backup requirements. For example, you
can set different management classes for each database.
Example 7-4 DB2 configuration
db2 => update db cfg for ITSRMDB using TSM_MGMTCLASS DB2_MGMTCLASS

Storing the API password
Example 7-6 shows how to configure these parameters into the Tivoli Storage Manager API
client, using the dsmapipw command.

*************************************************************
Enter your current password:bonniedb2
Enter your new password:bonniedb2
Enter your new password again:bonniedb2
Your new password has been accepted and updated.
Stop and re-start DB2 to allow the changes to take effect.

SQL1064N DB2STOP processing was successful.
C:\PROGRA~1\SQLLIB\BIN>db2start
SQL1063N DB2START processing was successful.
Client option files
Now configure the Tivoli Storage Manager API client option file, dsm.opt located in
C:\Tivoli\tsm\api\ so that DB2 will point to the correct Tivoli Storage Manager Server, BANDA.
Example 7-8 API dsm.opt file sample

As the DB2 database files are backed up using DB2, they must be excluded from backup by
the normal Backup/Archive client. We excluded all DB2 files except the recovery log files. You
must update the dsm.opt file located in c:\tivoli\tsm\baclient\ directory.

7.2.5 Additional considerations
The previous explanation shows you how to perform a basic configuration for Tivoli Storage
Manager, so that you can send DB2 backups directly to Tivoli Storage Manager storage.
However, you should note the following considerations:
򐂰 DB2 archives are generated on local disk. They must be protected against loss through
mirroring or archival. You can also activate an exit to automatically archive DB2 logs.
򐂰 Old database backups must be manually deleted from the Tivoli Storage Manager Server
once they are not needed using the db2adutl utility.
򐂰 Depending on your recovery requirements, you may have to configure additional DB2
parameters (such as NUM_DB_BACKUPS and REC_HIS_RETENTN).
See the redbook Backing Up DB2 Using Tivoli Storage Manager, SG24-6147 for detailed
information on setting up DB2 backups with Tivoli Storage Manager.
7.3 Backup procedures

The configuration files contain relatively static information. Therefore, we recommend using a
traditional incremental backup policy to backup the files. In addition, there will be report and
log files to be backed up. Again a traditional incremental backup method is appropriate here.
We show backup of a Linux Agent, SUSE82-1 using the Tivoli Storage Manager

7.3.3 IBM Tivoli Storage Resource Manager database
Depending on the availability you require from the Tivoli Storage Resource Manager Server,
you can choose between online and offline backups of the DB2 database. Offline backups will
require a shutdown of the DB2 database, which implies a shutdown of the Tivoli Storage
Resource Manager application. We explain here how to perform both an online and offline
backup of the Tivoli Storage Resource Manager DB2 database.
Note: Please refer to this documentation for detailed information about DB2 protection and
Tivoli Storage Manager integration:
򐂰 Backing Up DB2 Using Tivoli Storage Manager, SG24-6147
򐂰 IBM DB2 Universal Database - Administration Guide: Implementation - Version 7,
SC09-2944
򐂰 IBM DB2 Universal Database - Command Reference - Version 7, SC09-2951
Offline backup
An offline backup will run only if the database is not currently in use. You must stop the
database or at least close all connections. In our case, we do not have to stop the database
since Tivoli Storage Resource Manager is the application using it. Check this using the DB2
command shown in Example 7-12. We then stopped the Tivoli Storage Resource Manager
Server - this will close all active connections to the Tivoli Storage Resource Manager
database.

Online backup
An online backup can run while applications are still accessing the data. DB2 will manage the
enqueue process and will use its recovery log to track all changes made to the database
while the backup is running. Your database must be configured for online backups (see
Example 7-5 on page 377). The database backup procedure, ITSRMBackupOnline, displayed
in Example 7-15, includes:
1. List current connections.
2. Run backup of ITSRMDB database.
3. List current connections.
Example 7-15 ITSRMBackupOnline script
@ECHO ON

7.4.2 IBM Tivoli Storage Resource Manager Server files
Since our Tivoli Storage Resource Manager Server system also has an Agent running on it,
and the Server and Agent files are stored in the same directory structure, in this restore test
we will be recovering both the Server and Agent.
The restore procedure has the following steps:
1.
2.
3.
4.
5.
Stop the Tivoli Storage Resource Manager Server and Agent.
Delete Tivoli Storage Resource Manager directories.
Try to start the Server - fails.
Restore all deleted directories.
Successfully start the Tivoli Storage Resource Manager Server and Agent.
Example 7-19 shows the Server and Agent being stopped, the files being deleted, and the
Server and Agent failing to start.

We describe now the procedures we have used to recover from a complete loss of our Tivoli
Storage Resource Manager Server.
7.5.1 Windows 2000 restore
To restore our Tivoli Storage Resource Manager Server, we followed the procedure described
in Deploying the Tivoli Storage Manager Client in a Windows 2000 Environment, SG24-6141.
We have:
1. Installed Windows 2000 on the server using BONNIE as hostname
2. Installed Windows 2000 Service Pack 3
3. Installed the Tivoli Storage Manager Backup/Archive client and configured it to use our
Tivoli Storage Manager Server located on BANDA. Example 7-23 shows the minimal
client options file required for this.
Example 7-23 Minimal dsm.opt file
tcpserveraddress

banda.almaden.ibm.com
bonnie
4. Restored all the files on the boot partition (disk C:\) as displayed in Figure 7-13.

Note that after the restore of the boot partition you will be prompted that a reboot of the
system is required. Do not reboot at this time. You need to wait until after the System
Objects have been restored.

IBM Tivoli Storage Resource Manager: A Practical Introduction
At this stage, we are in the situation where all our software and configuration files have been
restored. We must now restore the ITSRMDB database to its latest available status.
7.5.2 ITSRMDB database restore
We used the procedure described in 7.3.3, “IBM Tivoli Storage Resource Manager database”
on page 382 to restore the ITSRMDB database. We were able to do a rollforward restore
since the DB2 logs were backed up to Tivoli Storage Manager before the crash. They were
restored during step 4 on page 396. Example 7-24 shows the output of the restore process.

7.6 Database maintenance
As with every database, basic maintenance should be applied to the Tivoli Storage Resource
Manager repository to avoid space and performance problems.
Tivoli Storage Resource Manager: database

Database should be checked for performance using
runstats
reorgchk
reorg table
db2rbind

runstats to update tables statistics
reorgchk to check need for tables reorganization
reorg to rebuild unordered tables and indexes

The runstats command is not mandatory since the statistics can be updated by the reorgchk
command. Also, you need to run a runstats command for each table while reorgchk
executes over all tables.
Example 7-26 shows the output of the reorgchk command on our ITSRMDB database.

-------------------------------------------------------------------------------CLUSTERRATIO or normalized CLUSTERFACTOR (F4) will indicate REORG is necessary
for indexes that are not in the same sequence as the base table. When multiple
indexes are defined on a table, one or more indexes may be flagged as needing
REORG. Specify the most important index for REORG sequencing.
The reorgchk command calculates three formulas (F1, F2, F3) for the tables and three
formulas (F4, F5, F6) for the indexes to determine if the table or index must be reorganized.
Each hyphen displayed in the REORG column indicates that the calculated results were
within the set bounds of the corresponding formula, and each asterisk indicates that the
calculated result exceeded the set bounds of its corresponding formula.
Table reorganization is suggested when the results of the calculations exceed the bounds set
by the formula.
Attention: Refer to the appropriate administration guide for your DB2 platform.
If a reorganization is recommended for a table or an index, this can only be done when no
activity is running against the database. This means that IBM Tivoli SAN Manager must be
stopped in order to reorganize the tables.
Example 7-27 shows an output of the reorg for the ITSRMDB DB2
TIVOLISRM.T_STAT_FILE table followed by a reorgchk on this table.

7.7 IBM Tivoli Storage Resource Manager with SQL-Server
All of the examples so far have shown DB2 as the database being used. Here we show some
examples using Microsoft SQL-Server instead. The database name is TivoliSRM.
We installed SQL Server 2000 and a new Tivoli Storage Resource Manager instance on
server GALLIUM. From an installation point of view, the process was very similar to when
DB2 was used. Other than a local Agent, this new server had no Agents, and no significant
amount of data was collected so the database was extremely small.
404
IBM Tivoli Storage Resource Manager: A Practical Introduction
We used the IBM Tivoli Storage Manager for Databases product to perform the backups for
the database. Since even in a production implementation of Tivoli Storage Resource Manager
the database will be reasonably small, we came to the conclusion that it would likely not be
necessary to use the incremental backup capability of Tivoli Storage Manager for Databases,
so all of our examples are using full backups and restores.
Figure 7-18 displays using the Tivoli Storage Manager for Database GUI to start the backup,
and Figure 7-19 shows that the backup completed successfully.

Both the backups and restores were quite straightforward. No special setup was required for
either Tivoli Storage Manager for Databases or Tivoli Storage Resource Manager. More
information on using Tivoli Storage Manager for Databases is available in the redbook Using
Tivoli Data Protection for Microsoft SQL Server, SG24-6148.
One small issue that we came across is that we received an error when performing the
restore when we had the SQL-Server Enterprise Console running. The error was reporting
that the restore process was unable to open the database in exclusive mode. It would appear
Chapter 7. Protecting and maintaining Tivoli Storage Resource Manager
407
that this kept a connection option with the database. We shut down the Enterprise Console
and the restore completed successfully.
7.7.1 Using Oracle for the IBM Tivoli Storage Resource Manager database
We have not tested backing up and restoring an Oracle database used with Tivoli Storage
Resource Manager, however, the same principles apply as already shown for DB2 and MS
SQL-Server. If you have a Tivoli Storage Manager Server, you can use the extra product IBM
Tivoli Storage Manager for Databases to backup and restore Oracle. More information on
backing up Oracle is available in the redbook Backing Up Oracle Using Tivoli Storage
Management, SG24-6249.

Introduction to Tivoli Enterprise Console (TEC)
Configuring Rule Base
Event format
Configuring TEC Event Console
Configuring IBM Tivoli Storage Resource Manager to forward events
© Copyright IBM Corp. 2003. All rights reserved.
411
8.1 Introduction to Tivoli Enterprise Console
The IBM Tivoli Enterprise Console (TEC) is a tool for receiving and processing formatted
events. It uses a database to store the actual events. This database is divided into two
separate tables: one to store the reception log and one to store the processed and probably
reformatted events. TEC depends on the Tivoli Enterprise Framework.
There are five processes which make up a TEC server (see Figure 8-1):
1. tec_reception - Receives events, places them in a reception buffer, and writes them into
the database using a Framework RDBMS Interface Module (RIM). After successfully
placing the event into the reception log in the database, the status of the event is WAITING.
2. tec_rule - When an event becomes WAITING, this will cause the tec_rule process to pull in
the event and place it into its Event Cache. The tec_rule process is configured using a
so-called Rule Base. This can be programmed using a Prolog based language. These
Prolog files are compiled and loaded into the tec_rule process. Based on the defined
rules, the events are treated accordingly. They can be reformatted, matched, related,
time-triggered, and actions can be executed.
3. tec_dispatch - When the tec_rule process finishes processing an event, it hands it over to
the tec_dispatch process. This process stores the events in to the database event
repository table using RIM. It then informs the tec_server process about successfully
processing the event, and if there are any tasks or actions to be executed, it informs the
tec_task process to do it.
4. tec_server - This is the master process of the TEC server. It monitors all the other
processes and stops and starts these. Additionally, it receives a PROCESSED signal from the
tec_dispatch and informs the tec_reception process to change the reception log of an
event to PROCESSED. This is stored in the database accordingly.
5. tec_task - This process executes any tasks or actions requested by the rule engine, and
optionally gives a return code back to it.

A Rule base is divided into event class definitions, which define the attributes of an event; and
rules, which define what should be done with an event.
IBM Tivoli Storage Resource Manager ships only a class definition file (so called baroc file)
but no rule file.
Events can be received either through Tivoli Enterprise Framework mechanisms (which
requires some software to be installed on each event sender) or through a socket connection
(which only requires that events are sent according to TEC formats). IBM Tivoli Storage
Resource Manager sends its events through a socket connection directly to the TEC server.
In order to view the events and assign them to administrators to be treated, there is a Java
based program called the TEC Console. This connects to the event repository using
Framework mechanisms (RIM) and a helper process called tec_ui_server. It can be
configured to show different views for different administrators. Events can be modified
graphically.

8.3 Configuring the Rule Base
In order to receive events from IBM Tivoli Storage Resource Manager in a TEC server, the
event class definitions which IBM Tivoli Storage Resource Manager uses must be imported to
the TEC server. If you do not import them, events will not show up on your TEC console and
parsing errors will appear in the TEC reception log. You can determine if your events are
received by the TEC server (but the definitions are not there) by issuing the wtdumprl
command on your TEC server. If you see any parsing errors (Example 8-1) on IBM Tivoli
Storage Resource Manager events, then you have not imported the class definitions.

To import the event class definitions, open the Tivoli Desktop and double click the Event
Server icon. In the window (Figure 8-3) you see the defined rule bases, with the active one
highlighted by an arrow.
Figure 8-3 Active Rule Base
Choose the active rule base and right-click it. Select Import (Figure 8-4).
Figure 8-4 Import Rule Base
Select the check-box Import Class Definitions and enter the fully qualified path to the
definitions file. This file is on the IBM Tivoli Storage Resource Manager CD and is called
tivoliSRM.baroc. (Our example uses a copy of this file on disk.)
Chapter 8. Integration with Tivoli Enterprise Console
415
The Position to insert depends on how many events you expect to receive from IBM Tivoli
Storage Resource Manager, and on the hierarchical dependencies inside the class structure.
Since the IBM Tivoli Storage Resource Manager classes depend only on the root EVENT, you
can put it right after that event class. However, since classes are matched from the top to
bottom, put the busiest event classes higher in the hierarchy rather than the less busy
classes. For example, we put it at the very bottom, because we do not expect very many
events (Figure 8-5).
Figure 8-5 Import Class Definitions
After the class definitions are imported, we must compile the rule base to incorporate the
changes (as shown in Figure 8-6). To compile, right-click the active rule base icon and select
Compile.
416
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 8-6 Compile Rule Base
Carefully check the output for any compilation errors. If there were none, load the rule base
(Figure 8-7). You must recycle the event server whenever you make any changes to the class
definitions. If you only changed rules, then recycling the event server is not necessary.
Figure 8-7 Load Rule Base
Stop and start the Event Server by right-clicking the icon on your Tivoli Desktop (Figure 8-8).

Figure 8-8 Restart TEC Server
8.4 Configuring TEC Event Console
The TEC Event Console allows you to view the events the TEC server has received and
processed. This is an installable Java GUI to install on desktop machines. You must be
assigned as an operator to an Event Console to view events. A Console can be divided into
multiple Event Groups, which sort the events in meaningful groups. Each Event Group
contains one or more Event Filters to separate events. This example assumes you are
working with a Tivoli administrative user ID, which is authorized to do TEC configurations. In
the Console in Figure 8-9, there is an Event Group named All which shows all the events.
418
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 8-9 TEC Console
To make the changes click the Windows menu and then Configuration (Figure 8-10).
Figure 8-10 TEC Console Configuration
In the Configuration dialog there are three folders:
򐂰 Event Groups
򐂰 Consoles
򐂰 Operators
First we have to create an Event Group to specify filters to sort out the IBM Tivoli Storage
Resource Manager events. Right-click Event Groups and select Create Event Group
(Figure 8-11).
Chapter 8. Integration with Tivoli Enterprise Console
419
Figure 8-11 Create Event Group
Name the Event Group (for example, ITSRM) and right-click it. Select Create Filter
(Figure 8-12).
Figure 8-12 Create Filter in Event Group
When the dialog opens up, enter a description to the filter and select Add Constraint
(Figure 8-13).
420
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 8-13 Event Group Filter
Choose Class as an Attribute and Operator In, then select SRMAlert in the Value window
(Figure 8-14).
Figure 8-14 Add Constraint
This will add a Constraint to our filter ITSRM. If you add multiple Constraints, they behave as
a boolean AND. If you add more filters to an Event Group they behave as a boolean OR. You
can test if your filter matches any events by clicking the Test SQL button on Figure 8-13. If
there are no events in the TEC repository, then you will get zero matching events. You can
view the Constraint in plain SQL by clicking the little arrow above the Help button on
Figure 8-13. It will display similar to Figure 8-15.
Chapter 8. Integration with Tivoli Enterprise Console
421
Figure 8-15 Event Group Filter
After creating the Event Group, we must assign it to a Console. We assume that you already
have a Console defined, so right-click it and select Assign Event Group. The menu in
Figure 8-16 appears.
Figure 8-16 Assign Event Group
Select the appropriate roles and click OK. You will see output similar to Figure 8-17.
422
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 8-17 Assigned Event Groups
Your Console should now have the ITSRM Event Group assigned to it (Figure 8-18).
Figure 8-18 Configured Console
After configuring the Event Console, you can look at the results by changing the view in the
Windows menu and choose Summary Chart View. The window that appears is the actual
event viewer, which shows all configured event groups (Figure 8-19).
Chapter 8. Integration with Tivoli Enterprise Console
423

If you click the bar of a particular event group, the event viewer for this event group opens
(Figure 8-20).
In the upper window space, you can see the events which you can modify and are assigned
for you to solve. You can acknowledge, close, and run tasks, or view the details of the
selected event.
Figure 8-20 TEC console
If you select an event and click the Details button, the window in Figure 8-21 opens. It
describes in plain text the most important details of the selected event.

itself to forward events to TEC. Open the IBM Tivoli Storage Resource Manager Desktop and
navigate to Administrative Services -> Configuration -> Alert Disposition and enter the
hostname of your TEC server and the port (Windows 5529, UNIX 0) in the TEC section on the
right (Figure 8-23).
Figure 8-23 Setting the TEC server properties
Save your changes by clicking on the Save button under the top menu.
This configuration only defines where TEC events should be sent to - we have not yet actually
enabled any events. To enable events for a specific topic in IBM Tivoli Storage Resource
Manager, you have to select the TEC check box on every Alert properties tab that you want ti
activate. For example, if you want a TEC event sent when the Default Scan fails, navigate to
its properties page and enable it (Figure 8-24).

9.1 Introduction to Tivoli Enterprise Data Warehouse
The Tivoli Enterprise Data Warehouse (TEDW) is an application used to collect and manage
data from various Tivoli and non-Tivoli system management applications. The data is
imported from the source applications, stored centrally, and further processed to fit the needs
of the end users. Figure 9-1 shows the basic components of the TEDW in the logical order of
the data flow.

Figure 9-1 Tivoli Data Warehouse data flow
The first step to introducing TEDW is enabling the source applications. This means to provide
all tools and customizations necessary to import the source operational data into the central
data warehouse. All components needed for that task are collected in Warehouse Packs for
each source application.
An important part of the Warehouse Packs is the ETL programs (Extract, Transform, and
Load). ETL programs process data in three steps. First they extract the data from a data
source. Then the data is validated, transformed, aggregated, and cleansed so that it fits the
format and needs of the data target. Finally, the data is loaded into the target database.
In TEDW there are two types of ETLs. The central data warehouse ETL pulls the data from
the source applications and loads it into the central data warehouse. The central data
warehouse ETL is also known as source ETL or ETL1. The second type of ETL is the data
mart ETL.
The central data warehouse (CDW) is the database that contains all enterprise-wide
historical data (with hour as the lowest granularity). This data store is optimized for the
efficient storage of large amounts of data and has a documented format that makes the data
accessible to many analysis solutions. The database is organized in a very flexible way, and
you can store data from new applications without adding or changing tables.
The data mart ETL extracts a subset of historical data from the central data warehouse that
contains data tailored to and optimized for a specific reporting or analysis task. This subset of
data is used to create data marts. Data mart ETL is also known as target ETL or ETL2 .
432
IBM Tivoli Storage Resource Manager: A Practical Introduction
A data mart satisfies the needs of a specific department, team, or customer. The format of a
data mart is specific to the reporting or analysis tool you plan to use. Each application that
provides a data mart ETL creates its data marts in the appropriate format.
TEDW provides a Report Interface (RI) that creates static two-dimensional reports of your
data using the data marts. The RI is a role-based Web interface that can be accessed with a
Web browser without any additional software installed on the client. You can also use other
tools to perform OLAP analysis, business intelligence reporting, or data mining.
The Control server is the system that contains the control database, which contains metadata
for Tivoli Enterprise Data Warehouse and from which you manage your data warehouse. The
Control server controls communication between the Control server, the central data
warehouse, the data marts, and the Report Interface.
The Control server uses the Data Warehouse Center to define the ETL processes and the
star schemas used by the data marts. You use the Data Warehouse Center to schedule,
maintain, and monitor these processes.
For more information about Tivoli Enterprise Data Warehouse, refer to Introduction to Tivoli
Enterprise Data Warehouse, SG24-6607.
9.2 Tivoli Storage Resource Manager Warehouse Pack
Tivoli Storage Resource Manager has a three-tier architecture: a user interface (UI)
component, a Server component, and an Agent component. Agents collect statistics about
accessible storage and send that information to the centralized Server. The Agent must be
installed on all of the machines where the user wants to monitor storage and storage activity.
The Server receives information from the Agent(s) and saves that information in the
Enterprise Repository (Figure 9-2).
The Tivoli Storage Resource Manager Warehouse Pack provides the steps that extract data
from the Tivoli Storage Resource Manager Enterprise Repository database. The central data
warehouse ETL transforms that data so it conforms to the central data warehouse format and
then loads it into the central data warehouse of Tivoli Enterprise Data Warehouse. Other
products, like Tivoli Service Level Advisor, pull data into data marts they provide to use with
service level agreement reports.
Collection of data from IBM Tivoli products into one central repository provides the user with
the opportunity to see trends in operation, resource usage and cross product interoperability.
Tivoli Storage Resource Manager historical data is available for use by Tivoli Service Level
Advisor (SLA) and Tivoli Storage Manager.
Consult the Tivoli Service Level Advisor documentation for information about its installation,
configuration, and use. Tivoli Enterprise Data Warehouse and IBM DB2 Data Warehouse
Center ETL processes are designed to perform data collection at least once a day.

9.3 Tivoli GUID and Data Warehouse
Some Tivoli products have adopted the use of a globally unique identifier (GUID) that is
permanently assigned to computer systems running storage products. Tivoli Storage
Resource Manager Version 1.2 implements this feature as a software identifier and the GUID
package is automatically installed on the Server and Agents . The GUID allows these
products to coordinate computer system data in the central data warehouse. The GUID is
recorded as an attribute in the central data warehouse for each Tivoli Storage Resource
Manager Server and Agent when available.
A STORAGE_GUID attribute will not be available for the monitored systems until all Agents
are updated to Tivoli Storage Resource Manager Version 1.2.
Consult the Tivoli Storage Resource Manager Version 1.2 documentation for a list of
platforms that support GUID.
9.4 Configuring TEDW: Importing Warehouse Pack
In this section we will describe how to import the Tivoli Storage Resource Manager
Warehouse Pack.

Figure 9-25 Enter password for DB2 CDW target
9.4.5 Configure ETLs
After we have successfully configured the ODBC database connections, we opened the
Subject Area folder and selected the BTM_Tivoli_Storage_Resource_Manager folder (from
Figure 9-21 on page 446) to configure the ETLs. You will see three ETL processes:
򐂰 BTM_C05_Initialize - Run this process only once as part of the installation of the
Warehouse Pack. It modifies the repository database of IBM Tivoli Storage Resource
Manager to incorporate the changes necessary to run Tivoli Data Warehouse.
򐂰 BTM_C10_ETL1 - The actual ETL process that gathers the data from the IBM Tivoli
Storage Resource Manager repository database into the CDW database. This should be
run daily.
򐂰 BTM_C15_Expire_Server - This process should only be run to remove all information and
statistics from the CDW.
A process can have different types of objects. The first process has only one actual
“executable” step, which you can see at the top position in the right window of Figure 9-26,
called Create Archive. These steps can have three different states:
򐂰 Development - Used for modifications
򐂰 Test - You can execute, but changes are rolled back after completion
򐂰 Production - You can execute and changes persist, but no configurations can take place
To run the process, right-click the process and select Mode -> Production (Figure 9-26).

The Warehouse Pack for IBM Tivoli Storage Resource Manager currently contains only the
ETL 1 process. To use the collected data, you can use Tivoli Service Level Advisor (TSLA).
The redbook Introducing IBM Tivoli Service Level Advisor, SG24-6611 explains how to
incorporate different Warehouse Pack data into the TSLA. It also explains how to extract data
and build reports with popular third-party Business Intelligence applications. Alternatively, you
can extract the data and use third party reporting tools as described in Introduction to Tivoli
Enterprise Data Warehouse, SG24-6607.
A future version of the Warehouse Pack for IBM Tivoli Storage Resource Manager will have
predefined reports and the data mart ETL 2.

10.1 Introduction to IBM Tivoli Configuration Manager
IBM Tivoli Configuration Manager, Version 4.2, is a solution for controlling software
distribution and asset management inventory in a multiplatform environment. It focuses on
deploying and managing software in complex, distributed enterprise environments. IBM Tivoli
Configuration Manager is a key solution to rapidly and efficiently deploying complex
mission-critical or desktop productivity applications to multiple locations from a central point
and to gather and maintain the inventory information about hardware and software assets,
easily, quickly, and accurately.
Tivoli Configuration Manager consists of the following main components:
򐂰 Inventory
򐂰 Software Distribution
Software Distribution enables you to install, configure, and update software remotely within
your network.
Inventory enables you to gather and maintain up-to-date inventory asset management
information in a distributed environment. This helps system administrators and accounting
personnel to manage complex, distributed enterprises.
Tivoli Configuration Manager also provides the following services:
򐂰

Activity Planner
Change Manager
Resource Manager
Web Interface
Enterprise Directory Query Facility
Activity Planner enables you to define a group of activities that originate from different
applications in an activity plan, submit or schedule the plan for running, and monitor the plan
while it runs.
Change Manager functions with Activity Planner to support software distribution, inventory,
and change management in large networks. It uses reference models to simplify the
management of the network environment.
You can use Resource Manager, together with Software Distribution and Inventory, to perform
the management operations for pervasive devices.
You can use the Web Interface to install and manage various Tivoli Configuration Manager
Web objects. The Web Interface has a server component that pushes software packages,
inventory profiles, and reference models from the Tivoli region to the Web Gateway where
they are stored until they are pulled by the Web Interface endpoint.
With enterprise directory integration, you can exploit organizational information that is stored
in enterprise directories in order to determine a set of targets for a software distribution or an
inventory scan. The Enterprise Directory Query Facility enables you to select a specific
directory object, or container of directory objects, as subscribers for a reference model or an
activity plan.

IBM Tivoli Storage Resource Manager: A Practical Introduction
10.2 Inventory - determine who has got which version
In order to determine which machine in your environment has got which product installed and
which version, you can use the Inventory part of IBM Tivoli Configuration Manager. The
process to query inventory information from your nodes includes four steps:
1.
2.
3.
4.
Create an inventory profile in Tivoli Framework
Distribute profile to endpoints
Build a query
Run the query
10.2.1 Create an inventory profile in Tivoli Framework
Open the Tivoli Desktop and navigate to your Inventory Policy Region. In our environment this
is done by opening the tonga-region Policy Region (Figure 10-1).
Figure 10-1 Tivoli Desktop
We created separate Policy Regions for each Tivoli product. Double click Inventory Policy
Region (Figure 10-2).
Chapter 10. Integration with Tivoli Configuration Manager
459
Figure 10-2 Policy Region tonga-region
Make sure that the Inventory Policy Region contains the InventoryConfig resource as a
Managed Resource. To determine if it has been set, right-click the Policy Region and select
Managed Resources. The dialog in Figure 10-3 appears.
Figure 10-3 Managed Resources for Inventory
For our environment we created the default Query Libraries with the script
inventory_query.sh in the bin/generic/inv/SCRIPTS/QUERIES directory of the Tivoli
installation directory and created a Profile Manager called Inventory_default_PM.
(Figure 10-4). To create a Profile Manager select Create in the top menu and select Profile

Manager.
Figure 10-4 Policy Region Inventory
Double click the Profile Manager and the dialog in Figure 10-5 appears.
Figure 10-5 Profile Manager Inventory
Chapter 10. Integration with Tivoli Configuration Manager
461
Create an Inventory Profile by clicking Create in the top menu and select Profile. Enter the
name and select InventoryConfig as the Profile type. Right-click the newly created Profile
and select Edit. The screen that appears shows you the global properties of the Inventory
Profile (Figure 10-6).
Figure 10-6 Inventory Profile Global Properties
Since we want to create a software only inventory scan, you should deselect all hardware
related check boxes. The only ones we need is the PC Software section (Figure 10-7) and the
UNIX Software section (Figure 10-8).
462
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 10-7 Inventory Profile PC Software
There are two possible ways to collect software information from endpoints. One is to scan all
the files on your machine and compare them to a predefined list, thus determining an installed
product by filename and size of a significant file in the software package. IBM Tivoli Storage
Resource Manager ships these so called Inventory Signature files with the product. They can
be found in the installation directory in the TIVINV subdirectory. The signature files are zero
bytes in length and are recognized by filename (TSRM01_02.SIG for the IBM Tivoli Storage
Resource Manager - Manager Version 1.2). The signatures for IBM Tivoli Storage Resource
Manager are already incorporated in the latest inventory signature files, which you can
download from the IBM Software support Web site.
Another way to determine installed software is to query the native software repository of the
OS. This gives you very fast scans, but relies on the fact that the software has registered itself
in the OS during installation, rather than just copying files.
For IBM Tivoli Storage Resource Manager you can do both - the choice for your environment
depends on the practices of your IBM Tivoli Configuration Manager environment.
In our examples we chose to use the native software query, so we check just the Scan
Registry for Product Information boxes in the dialog (Figure 10-8), not the Scan for File
Information
Chapter 10. Integration with Tivoli Configuration Manager
463
Figure 10-8 Inventory Profile UNIX Software
Click OK to close the dialog and distribute the Inventory Profile to your Endpoints. Right-click
on the Profile and select Distribute (Figure 10-9).
464
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 10-9 Distribute Inventory Profile
This opens a dialog where you can choose the machines which will run the inventory scan.
After selecting, click on the Distribute & Close button (Figure 10-10).
Chapter 10. Integration with Tivoli Configuration Manager
465
Figure 10-10 Distribute Inventory Profile dialog
You can determine the status of the inventory scan with a tool called Distribution Status
console. If it is installed, you find it on the main screen of your Tivoli Desktop (Figure 10-1 on
page 459). Double click on the icon and a console opens (Figure 10-11).
466
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 10-11 Distribution Status Console
In the upper window, double click on the Inventory Scan distribution and in the lower window
select All Nodes. You can see which scans are successfully completed, pending, failed etc.
When the scans are all finished, you can query the collected information. There are many
standard queries, but we want to gather only the data for IBM Tivoli Storage Resource
Manager. Therefore we create a new query by selecting Create -> Query (Figure 10-12).
Figure 10-12 Create Query Library
Name the Query and select inv_query as the repository. This is the Inventory Database RIM
object. The table containing the native software information is NATIVE_SWARE_VIEW.
Select the columns you want and add a filter: Column name PACKAGE_NAME = ‘IBM Tivoli
SRM’ (Figure 10-13).
Chapter 10. Integration with Tivoli Configuration Manager
467
Figure 10-13 Edit Inventory Query
Click Run Query to execute the query while it is being edited. The output shows all the
installed IBM Tivoli Storage Resource Manager products including Agents, Manager and
Consoles (Figure 10-14).
468
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 10-14 Output for IBM Tivoli Storage Resource Manager Query
You can also query the Inventory database with a native DB2 client. That enables you to
connect to Business Intelligence tools or script based applications.
Play around with the queries and you will find that there is much additional information which
can be obtained from them. In combination with the hardware inventory scans, you can
determine which Fibre Channel cards are in your systems, and which firmware levels and
drivers they are using. In the following query output we queried all the IBM software which
was on the endpoints (Figure 10-15).
Figure 10-15 Output for IBM Query
Chapter 10. Integration with Tivoli Configuration Manager
469
10.3 Software distribution
To automatically deploy a large number of IBM Tivoli Storage Resource Manager Agents, you
can use the Software Distribution component of IBM Tivoli Configuration Manager. The
distribution process has four steps:
1.
2.
3.
4.
build software package with the Software Package Editor
create software distribution profile in Tivoli Framework
import and build software package
perform installation/uninstall tasks
10.3.1 Build software package with Software Package Editor
Before you can use the Software Package Editor you have to install it from the Configuration
Manager CD. It must be either installed on a managed node or a Tivoli endpoint so that the
software packages, once built, can be automatically fetched from the host. Figure 10-16
shows the Software Package Editor with a new package which we called ITSRM-Agent.
Figure 10-16 Software Package Editor with new package ITSRM-Agent
You can build one package for each platform or all platforms in one. The benefit of separating
the packages by operating system is that you prevent having to download all the code to all
the endpoints before installation occurs. If temporary space is an issue, you should split into
multiple packages. This in turn makes it slightly more complicated in installation tasks,
because you have to group the endpoints by operating system. We will give some simple
examples here, but if you already have a production ready installation of Configuration
Manager, then the design rules will be in place, and you should build the packages according
to them.
Right-click the package name and select Properties. The dialog in Figure 10-17 displays.
Enter the package version and a title for your package. Leave all the other parameters at their
default values.
470
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 10-17 Properties dialog
For the actual installation we use the command line procedure. First copy the installation
media to the hard drive. We only need the setup.exe and the directories install, java and
agent (Figure 10-18).
Figure 10-18 Agent installation directories
After setting the package properties, we add objects to the package. From the screen in
Figure 10-16, click the tab Execute program as shown in Figure 10-19.
Chapter 10. Integration with Tivoli Configuration Manager
471
Figure 10-19 Add an execute program action to the package
With this type of action you can distribute files to the endpoint, run the provided script and
delete the temporary files. During the Tivoli Storage Resource Manager installation, the setup
program ends at once and additional processes are spawned. For this reason, we cannot use
software distribution for corequisite files since these file would be deleted, when they are still
needed. Therefore, we need additional actions to distribute the installation media.
After selecting the the action, the Execute Program Properties dialog appears (Figure 10-20).
Figure 10-20 Install dialog
Enter the full path to the installation setup program. The example shows the installation of the
Windows agent. This must be the path as it appears after transferring the files to the endpoint,
472
IBM Tivoli Storage Resource Manager: A Practical Introduction
which could be different from the directory structure on the node where you are building the
filepack. Do not include any arguments, then select the Advanced dialog (Figure 10-21).
Figure 10-21 Advanced tab
In the arguments field, enter the parameters for silent installation. The syntax is:
setup.exe -s servername -d installdir -p serverport -q agentport -x (no scripts from
server) -n (no initial scan)
For example, the only non-default parameters are to specify server name (WISLA) and no
initial scan of the Agent. The full installation command is:
setup.exe -s wisla -n
The Working Directory entry points to the installation directory. Optionally, you can redirect
standard out and standard error to files. Click OK to end the dialog.
This should be sufficient for the installation process. Configuration Manager can also do
deinstallation, so to configure the deinstallation process select the Remove tab from
Figure 10-20 on page 472, as shown in Figure 10-22.
Chapter 10. Integration with Tivoli Configuration Manager
473
Figure 10-22 Remove dialog
A single command is sufficient to remove the software. The path to the deinstallation program
is in the installation directory of the IBM Tivoli Storage Resource Manager agent. We need an
argument for the uninstallation program. To open the dialog, click Advanced (Figure 10-23).
474
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 10-23 Advanced properties
The parameters to specify are java -uq. This procedure is not documented in the manual, but
is derived from the script to remove the UNIX agents and proved to work well. Be sure to add
the working directory for the process.
We chose to make just one software package for Windows and AIX machines. To prevent
execution on an AIX machine, you can specify a condition when to run that action, using the
Condition button at the top right hand corner of Figure 10-22. Figure 10-24 displays.
Chapter 10. Integration with Tivoli Configuration Manager
475
Figure 10-24 Condition
Choose os_name from the list box, add an == operator, and enter Windows_NT. This will
ensure execution only on the desired platform.
Using the same procedure, we added an extra action for the AIX installation, starting from the
Execute Program Properties dialog shown in Figure 10-20 on page 472. The actions to define
are mainly the same except for the paths and the setup.aix program. Also, we added a
condition that allows execution only on AIX machines.
Since we can not download the installation media with the Execute Program action, we have
to distribute it with an extra step.
In the main screen of the Software Package editor (Figure 10-16 on page 470), choose the
Add Object tab and click the Add Directory icon. The dialog in Figure 10-25.
476
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 10-25 Add Directory dialog
To ensure all subdirectories are getting copied, choose the Advanced button on the lower left
corner, and select the Descend Directories check box (Figure 10-26).
Figure 10-26 Descend Directories
The ready-to-build software package is shown in Figure 10-27.
Chapter 10. Integration with Tivoli Configuration Manager
477
Figure 10-27 Ready-to-build software package
Save this package to an .sp file on your server and exit the Software Package Editor.
10.3.2 Create software distribution profile in Tivoli Framework
Open your Tivoli Desktop and navigate to the Software Distribution policy region. Make sure it
has the Software Distribution package as a managed resource in the properties menu. To
determine if it has been enabled, click on Properties -> Managed Resources and check if
the SoftwarePackage resource is on the left side. Then create a Profile Manager for use by
IBM Tivoli Storage Resource Manager packages (Figure 10-28).
Figure 10-28 Policy Region with Profile Managers
Double-click the object PM_SD_ITSRM to open the Profile Manager, and create a Profile with
the name of your file package including the version (Figure 10-29).
478
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 10-29 Create Software Package Profile
After you have created the Profile, an empty package icon appears in the Profile Manager.
Add any subscribers for the distribution of the package.
Figure 10-30 Profile Manager with Profiles and Subscribers
Chapter 10. Integration with Tivoli Configuration Manager
479
Next we need to import the previously defined Software package to the Profile we just
created. Right-click the Profile and choose Import (Figure 10-31).
Figure 10-31 Import Software Package
A dialog appears, where you can select the node on which you have previously created the
Package and the path to the .sp file. Checking Build, will include all the source files and
programs and actions into one single file (.spb) to be distributed to the target endpoint. Enter
the location where you want to store the .spb file. You might want to store it on your software
distribution server or on any of your software depot servers. If your are rebuilding it, check
Overwrite (Figure 10-32).
480
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 10-32 Import and build a software package
The package icon of the should now be a sealed package, ready to ship to your targets. For
installation to occur, right-click the package and choose Install (Figure 10-33).
Chapter 10. Integration with Tivoli Configuration Manager
481
Figure 10-33 Install a software package
The install dialog, which is shown in Figure 10-34, lets you select on which endpoints to install
the software. Our package will work on Windows and AIX servers. Additional checks can be
made, eg. whether the software is already installed or with the Change Manager feature, if
you are allowed to install the software due to licensing issues. For additional information see
the redbook All About IBM Tivoli Configuration Manager Version 4.2, SG24-6612.
482
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 10-34 Install Software Package
You can also schedule the installation and query inventory to look for hardware or software
Constraints. To ensure that every host in your environment has an IBM Tivoli Storage
Resource Manager agent, you can use the strategies described in Implementing Automated
Inventory Scanning and Software Distribution After Auto Discovery, SG24-6626, to discover
new nodes through Tivoli NetView, install an endpoint, perform an inventory query, and
automatically deploy the S agent on them.
Another method of identifying hosts to install software on, is querying an LDAP directory like
Microsoft Active Directory or IBM Directory with the Enterprise Directory Query facility. Then
you would be able to create a machine group for IBM Tivoli Storage Resource Manager, and
automatically deploy the software once a machine belongs to the group.
Configuration Manager enables you to remove the software as well. For this function,
right-click the package and select Remove (Figure 10-35).

11.1 Introduction to IBM Tivoli Monitoring
Figure 11-1 presents a high-level overview of the interaction between various components of
IBM Tivoli Monitoring 5.1. The IBM Tivoli Monitoring 5.1 profile contains, among other
information, a resource model. The resource model is a collection of monitors that correlate
amongst themselves before attempting to perform a notification action. The IBM Tivoli
Monitoring 5.1 profile is distributed to the endpoints to monitor one or more resources
(examples of typical resources are hard disk space, paging space, and process/service).
Based on configuration settings in the IBM Tivoli Monitoring 5.1 profile, the engine runs on the
endpoint and performs the necessary monitoring on the resources that are specified in the
distributed resource model(s). The Web Health Console obtains logged data from selected
endpoints and displays the “health” of the endpoints for their resources.

If you want in depth monitoring for your IBM Tivoli Storage Resource Manager DB2 instance,
you can use these additional modules.
In our examples here, we use the shipped monitor Parametric Services to watch the status of
the Windows services, which are required to run IBM Tivoli Storage Resource Manager.
Additionally, there is a default action to restart stopped services.
11.3 Daemons to monitor and restart actions
This section describes how to configure IBM Tivoli Monitoring to monitor the IBM Tivoli
Storage Resource Manager Windows services.
Open the Tivoli Desktop and navigate to your Monitoring Policy Region (Figure 11-2).
Figure 11-2 Policy Region tonga-region
Create a profile manager to contain the monitoring profiles. Select Create -> Profile
Manager and create a dataless Profile manager, called PM_DM_ITSRM in our example
(Figure 11-3).
Chapter 11. Integration with Tivoli Monitoring
487
Figure 11-3 Profile Manager PM_DM_ITSANM
Open the Profile Manager, select Create -> Profile and choose a Tmw2kProfile (which is the
Monitoring profile resource). If this entry does not show up in the list, make sure the
Tmw2kProfile is in the managed resources list of the Policy Region. Figure 11-4 shows a
Profile called P_DM_ITSRM in .
Figure 11-4 Create Monitoring Profile
Double click on the newly created profile and in the screen that appears, click Add with
Defaults. This opens a chooser window, where you can select the resource model you want
to add to your profile. In the Category list box, choose Windows and select the Parametric
Services entry (Figure 11-5).
488
IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 11-5 Add Parametric Services Model to Profile
After adding the resource model, we have to edit the model to include the services we want to
monitor. For that, click Edit (Figure 11-6).
Chapter 11. Integration with Tivoli Monitoring
489
Figure 11-6 Edit Resource Models
In this window, we can adjust all attributes belonging to that resource model. To specify the
services to monitor open the Parameters window (Figure 11-7). You must enter the names of
the services exactly as they appear in the Windows Registry under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services. The services which IBM
Tivoli Storage Area Network Manager needs to run are:
򐂰 DB2
򐂰 TSRMagt1
򐂰 TSRMsrv1

IBM Tivoli Storage Resource Manager: A Practical Introduction
Figure 11-7 Parameters of Resource Model
Click Apply Changes and Close to close the window, bring up the next dialog with the
Indications button. As you can see from the definitions, the default action, when a service is
stopped or failed, is to restart the service automatically. Additionally a CRITICAL TEC event is
generated (Figure 11-8).
Chapter 11. Integration with Tivoli Monitoring
491
Figure 11-8 Indications and actions of resource models
To enable the TEC events globally for this Profile and to specify to which TEC server the
events are sent, click on the Properties menu in the Profiles main window (Figure 11-4 on
page 488) and the following screen will open (Figure 11-9).
Figure 11-9 TEC forwarding of events from Monitoring
492
IBM Tivoli Storage Resource Manager: A Practical Introduction
Select the Send TEC Events check box and choose the event delivery method and TEC
server. The TME® (Secure) Delivery is (in most cases) the better choice, because it caches
events if the Event Server is temporarily unavailable.
Close the windows with the OK button until you are back in the Profile Manager main window.
(Figure 11-10). Subscribe the endpoints running the IBM Tivoli Storage Resource Manager Manager with Profile manager -> Subscriber and distribute the Profile using Profile
Manager -> Distribute -> Distribute Now.
Figure 11-10 Profilemanager for Monitoring
You can determine if your resource models are running on a particular endpoint by issuing the
wdmlseng command at thecommand line on your Tivoli Managed Region (TMR) server.
Example 11-1 shows typical output.

redbook. The first group of scripts shows how to use IBM Tivoli Storage Resource Manager
for Databases together with IBM Tivoli Storage Manager to manage database space. The
second group consists of backup and restore scripts for the IBM Tivoli Storage Resource
Manager repository are provided. Those scripts are intended to provide basic samples only of
the functionality described. They must be modified, customized, and tested according to the
operating system, the volume manager, the database manager, the backup software, or any
other software used in your environment.
These scripts can be downloaded as described in “Locating the Web material” on page 503.

IBM Tivoli Storage
Resource Manager:
A Practical Introduction
Take control of
storage resources in
your enterprise
Receive early alerts of
storage problems
New! ESS reporting
and Tivoli integration
Storage growth continues to accelerate, and the cost of disk can
approach 80% of total system hardware costs. Yet, the storage in
most businesses is typically only about 50% used. How can you
take control of your storage assets to render utilization more
efficient, and make the most of your storage dollars?
IBM Tivoli Storage Resource Manager helps you discover,
monitor, and create enterprise policies for your filesystems and
databases. You will find out where all your storage is going, and
be able to act intelligently on this information. Application
availability is improved because you will have early warnings
when filesystems are running out of space. If you are thinking
about server consolidation, you can use IBM Tivoli Storage
Resource Manager to help efficiently utilize your accumulated
storage resources.
This IBM Redbook shows how to install, configure, and protect
the IBM Tivoli Storage Resource Manager environment; how to
create policies; how to define automated actions like scripts or
SNMP events when policies are violated; and how to produce
detailed, meaningful storage reports. This book is intended for
those who want to learn more about IBM Tivoli Storage Resource
Manager, and for those who are about to implement it.
The second edition of this redbook is updated for IBM Tivoli
Storage Resource Manager Version 1.2.
