Introduction to the
vRealize Operations Management
Pack for Storage Devices
1
The Management Pack for Storage Devices provides you with a complete view of your entire storage
topology from your host, through your storage network, and out to the storage array. With this solution,
you can use vRealize Operations Manager to monitor and troubleshoot capacity and performance problems
on different components of your storage area network.
The Management Pack for Storage Devices has the following features:
Provides an end-to-end view of topology, statistics, and events at every affected level of the storage area
network.
n
n
Enables a vSphere administrator working with a virtual environment to isolate problems caused by
elements in the physical storage stack, such as the Host Bus Adapter (HBA), storage switches, and
array. The vSphere administrator uses this information to hand off the problem to the domain
administrator for further analysis.
n
Captures and analyzes information for throughput and latency on the HBA and mount objects.
Captures throughput on the switch ports.
n
Captures IOPS and queue depth at the HBA and switch ports for read and write components.

Installing and Configuring the
Management Pack
2
When you install a management pack, you install the PAK file that you downloaded as part of the solution,
and you configure the management pack instance.
This chapter includes the following topics:
n
“Install the Management Pack,” on page 9
n
“Add Credentials and Fabric Servers for the Management Pack for Storage Devices,” on page 10
n
“Verify That Your Management Pack for Storage Devices Is Connected and Collecting Data,” on
page 12
n
“Ports and Log Files,” on page 13
Install the Management Pack
If your environment includes multiple vCenter Server systems on the same storage network, you must add
fabric switch CIM servers for each adapter instance. The adapter instance provides you with a holistic view
of the storage network connected to the vCenter Server system. The adapter discovers the storage devices
only for the ESXi 5.1 update 2 and later.
NOTE Any adapter credentials you add are shared with other adapter administrators and
vRealize Operations Manager collector hosts. Other administrators might use these credentials to configure
a new adapter instance or to move an adapter instance to a new host.
Prerequisites
Verify that the following conditions are met:
n
Read-only credentials are not adequate to connect and collect data from the vCenter Server and fabric
CIM servers. You must provide credentials with sufficient privileges. If the user account has limited
access to objects in vCenter and the fabric CIM server, you can only collect data from objects for which
you have permission.
n
The CIM agent is enabled on all storage network switches from which you are collecting data, and that
you can provide credentials with sufficient privileges to connect and collect data. If the user account has
limited access to objects in the storage environment, you can only collect data from objects for which
you have permission. Credentials must include at least read permissions.
n
All storage network switches with the CIM agent enabled are added to DCNM or BNA solutions.
n
The fabric CIM service supports switch profile and fabric profile. The supported versions for the Fabric
Profile are 1.1 to 1.6.
VMware, Inc.

vRealize Operations Management Pack for Storage Devices 6.0.3 Guide
n
A vSphere API for Storage Awareness (VASA) provider is registered as a storage provider with the
vCenter Server host for your adapter instance. VASA providers gather information from arrays that
support the environment and provide the data to vCenter Server system. If the VASA provider is not
registered with vCenter Server host, the Management Pack for Storage Devices cannot discover objects
in the array. The minimum support version is VASA 1.0. See information regarding storage providers
in the ESXi and vCenter Server 5.5 Documentation.
n
Specify the search domain value on vRealize Operations Manager to reach vCenter, hosts, and switches
using their Domain Name System (DNS) names instead of IP addresses. The resolv.conf file is used by
vRealize Operations Manager to connect to remote machines over the network. You must configure the
file correctly so that vRealize Operations Manager can reach the destination machines, such as vCenter,
ESXi hosts, or Fibre Channel (FC) switches. As a workaround, you can specify the search domain in
the /etc/resolve.conf file on vRealize Operations Manager and then restart the collector.

User Scenario: An Object in Your
Storage Network Has a Performance
Problem
6
A user reports that a virtual machine is running slow. She is not sure how long the problem has existed, but
needs to process data overnight and wants to know if she can start the task before she leaves for the day.
As the system administrator, you realize that the problem might not be with the virtual machine itself.
Rather than investigate the state of only the virtual machine, you begin by reviewing the dashboard that
shows the state of all storage network objects associated with the virtual machine.
Procedure
1
See the topic called User Scenario: Use the Troubleshooting Dashboard to Locate the Real Problem
Source
As the system administrator for the data center, you must locate the user's virtual machine in the
network storage topology so that you can determine if the problem is with the host system or
somewhere else in the storage network.
2
See the topic called User Scenario: Examine Metrics to Find the Root Cause
To determine if the virtual machine performance problem is temporary or indicates a more serious
problem in the storage network, you create metric charts to identify the root cause of the problem.
This chapter includes the following topics:
n
“User Scenario: Use the Troubleshooting Dashboard to Locate the Real Problem Source,” on page 39
n
“User Scenario: Examine Metrics to Find the Root Cause,” on page 40
User Scenario: Use the Troubleshooting Dashboard to Locate the
Real Problem Source
As the system administrator for the data center, you must locate the user's virtual machine in the network
storage topology so that you can determine if the problem is with the host system or somewhere else in the
storage network.
The fastest way to inspect all of the components connected to the virtual machine is to look at the
Troubleshooting dashboard. Start by locating the problematic object.
Procedure
1
Click the Troubleshooting dashboard.
The dashboard displays badges for all the objects that the Management Pack for Storage Devices
discovered in the storage area network.
2
VMware, Inc.
In the group of virtual machines displayed, point to each badge icon to see the object name.
39
vRealize Operations Management Pack for Storage Devices 6.0.3 Guide
3
Identify the virtual machine that the user reported as slow and select the badge.
This action highlights all the objects in the storage area network path from the host system to the
storage mount that are associated with the virtual machine.
4
Review highlighted objects that appear with a red, orange, or yellow condition.
5
Select an object to inspect problems or alerts reported in the widgets on the right.
Problems such as low throughput do not generate alerts but can affect performance.
You identified storage components associated with the virtual machine that have problems. You can now
select one of the components to examine faults, anomalies, and metrics on that object and determine if its
problems are the root cause of problems seen on the virtual machine.
User Scenario: Examine Metrics to Find the Root Cause
To determine if the virtual machine performance problem is temporary or indicates a more serious problem
in the storage network, you create metric charts to identify the root cause of the problem.
You used the Troubleshooting dashboard to find an object networked to the problematic virtual machine
that is not operating at an optimum. Now you want to investigate the performance of that object over a
period of time.
Procedure
1
If you are on the Troubleshooting dashboard with the problematic virtual machine selected, select a
highlighted object that appears with a red, orange, or yellow condition.
2
Double-click the object to access collected metrics.
The left pane displays the object name and the related objects. The main pane displays the Summary
tab.
3
Click the Troubleshooting tab, and click the All Metrics tab.
Throughput, latency, and error metrics are the most useful troubleshooting metrics.
a
Select the error statistics and double-click an entry to determine if errors occurred over time. Errors
can indicate when the component had trouble accessing the network.
b
Select the derived statistics and double-click the use to see a historical graph of the component use
over time. Slow throughput can occur during times of high workload.
c
Select the derived statistics and double-click the latency to see a historical graph of the time
required to process IO requests. High latency can indicate that the component had trouble
receiving data from the network.
What to do next
If the error statistics show no problems and derived statistics show a cyclical use pattern on the component,
you can call the user and explain that the problem might be temporary and when IO traffic throughout the
network drops, the virtual machine will become more responsive.
If the error statistics show no problems and derived statistics show consistently low use of the component
but the latency is suddenly high, another component on the network might be causing connectivity to time
out. Check for a faulty switch or other faulty component on the network.
