This includes Dell PowerEdge™ servers, Dell OptiPlex™ desktops, Dell Precision™ workstations and Dell PowerConnect™ switches. ITA consists of two tiers that can be installed on separate systems. The user interface tier (GUI) provides the interface to monitor and manage the devices on the network. This tier can be installed on multiple systems. The network monitoring and database tier is installed on a single system. This tier provides the active monitoring of the network devices and serves data to the systems installed with the user interface tier. In many cases both tiers will be installed on the same system. Once installed and configured, the ITA Network Monitoring component discovers devices on the network. It also stores information about these devices in the ITA database. This is depicted in Figure 1. Dell OpenManage IT Assistant version 6.4.4 is the first version that supports Windows® Server 2003. Previous versions of IT Assistant are not supported on Windows Server 2003. This is due to changes in the encryption model that is used by Windows Server 2003. This paper is intended to help administrators migrate systems that have IT Assistant installed to Windows Server 2003 without losing information stored in the ITA database. It also addresses some ITA configuration settings that are required when used on a Windows Server 2003 installation. Revision Date: 5/5/2017 Page 3 Systems Management Group Figure 1: Representation of the Two Tiers in IT Assistant Commonly Used Terms ITA Management Station: A system running both the IT Assistant user interface tier (GUI) and network monitoring and database tier. OpenManage Client Instrumentation: The agent located on Dell client systems (OptiPlex, Latitude and Dell Precision) that provides reporting on the system health and status. OpenManage Server Administrator: The instrumentation located on Dell PowerEdge servers. Revision Date: 5/5/2017 Page 4 Systems Management Group Section 2 Migrating to Windows Server 2003 Prior to migrating the Management Station’s operating system to Windows Server 2003, the administrator will need to save the IT Assistant configuration and management data as well as uninstall IT Assistant. The steps to do this are summarized in Figure 2. Figure 2: Steps to Preserve the IT Assistant Database Revision Date: 5/5/2017 Page 5 Systems Management Group The steps for preserving the ITA database during migration to Windows Server 2003 are as follows: On the ITA Management Station, back up the local ITA database named ITAssist. The local ITA database can be backed up through the ITA database utility named dcdbmng. The ITA database utility must be executed from the <IT Assistant installation>/bin directory. (The ITA database utility is typically located in C:\Program Files\Dell\OpenManage\It Assistant\bin.) Create a temporary folder such as “ITA_DB_backup” on the hard drive or on a share. Export the IT Assistant database by executing the command: dcdbmng /X c:\ITA_DB_backup NOTE: Always make a backup of the exported ITA database in case any failures occur during the upgrade to Windows Server 2003. Figure 3: Example of Exporting IT Assistant Configuration and Management Data Once the IT Assistant database is successfully exported, the pop up in Figure 4 is displayed on the screen. Figure 4: Pop up dialog box on IT Assistant Database Export. A successful export can also be verified by viewing the files in the ITA_DB_backup folder. There should be several files with a .txt extension. Revision Date: 5/5/2017 Page 6 Systems Management Group Figure 5: Example of Files in the ITA_DB_backup Folder. Example of files exported from IT Assistant version 6.4.3 in the ITA_DB_backup folder is depicted in Figure 5. For detailed information about the ITA database, please refer to the Dell OpenManage white paper “Getting to Know the OpenManage IT Assistant Database” by Haihong Zhuo. Uninstall IT Assistant from the ITA Management Station. (IT Assistant must be uninstalled because previous versions of Dell OpenManage IT Assistant are not supported on Windows Server 2003.) Once the un-installation is completed, confirm deletion of all ITA components and reboot the system. Upgrade ITA Management Station to Windows Server 2003. Install IT Assistant version 6.4.4 or greater on the system. Verify that the IT Assistant Network Monitoring and IT Assistant Connection Services are running after a reboot. Confirmation that both programs are running can be obtained by going to the Service Control panel and clicking on Start->Settings->Control Panel->Administrative Tools->Services Revision Date: 5/5/2017 Page 7 Systems Management Group Figure 6: Service Control Panel Verifying that IT Assistant Services have Started Clear the SNMPEventSeverityConfiguration table prior to importing the backed-up ITA database. Clearing the SNMPEventSeverityConfiguration table is done through the ITA database utility named dcdbmng. The dcdbmng utility must be executed from the <IT Assistant installation>/bin directory. The bin directory is typically located in C:\Program Files\Dell\OpenManage\It Assistant\bin.) Clear the table specified above by executing the following command: dcdbmng /Z SNMPEventSeverityConfiguration Figure 7: Example of Clearing SNMPEventSeverityConfiguration Table in the IT Assistant Database. Revision Date: 5/5/2017 Page 8 Systems Management Group Once the SNMPEventSeverityConfiguration table is successfully cleared, the pop-up in Figure 8 is displayed on the screen. Figure 8: Pop-Up Dialog Box on Clearing SNMPEventSeverityConfiguration table from IT Assistant Database. On the ITA Management Station, import the backed-up ITA database located in the ITA_DB_backup. Importing the backed-up ITA database is done through the ITA database utility named dcdbmng. The ITA database utility must be executed from the <IT_Assistant_installation>/bin directory. (The ITA database utility is typically located in C:\Program Files\Dell\OpenManage\It Assistant\bin.) Import the database by executing the following command: dcdbmng /M c:\ITA_DB_backup Figure 9: Example of importing the IT Assistant database. Once the IT Assistant database is successfully imported, the pop-up in Figure 10 is displayed on the screen. Figure 10: Pop-Up Dialog Box on IT Assistant Database Import Revision Date: 5/5/2017 Page 9 Systems Management Group Clear the User’s information table from the ITA database. Clearing the user’s information table is done through the ITA database utility named dcdbmng. The ITA database utility must be executed from the <IT Assistant installation>/bin directory. (The dcdbmng utility is typically located in C:\Program Files\Dell\OpenManage\IT Assistant\bin.) Launch the IT Assistant database utility dcdbmng graphical interface on the ITA Management Station as shown in Figure 11 by executing the following command (without arguments): dcdbmng NOTE: The users table stores authentication information for logging into the ITA User Interface. When logging into the ITA User Interface the first time on a new install, the table is empty. The IT Assistant’s authentication function checks for entries in the user’s table. If none are present, then it will add two entries, one for the user “itadmin” and the other for “anonymous”. Empty passwords for both users are created using the Windows encryption API. The password for the “itadmin” user can be modified later through IT Assistant’s User Interface. This can be found on blue navigation bar under Options-> Change IT Assistant Password . Clearing the users table will clear the modified password for “itadmin” and set this to empty. The “itadmin” user has “Read/Write” access to IT Assistant configuration options while the “anonymous” user has “Read Only” access. Figure 11: IT Assistant Database Management Utility’s GUI Once the graphical interface has appeared, expand the ITAssist entry in the left pane by clicking on the plus sign (+). Scroll down to the Users Information Table (Users) and right click on this table. A pop-up menu will display Import Table, Export Table and Clear Table selections. Select Clear Table to clear the information stored in the Users Information table. Revision Date: 5/5/2017 Page 10 Systems Management Group Figure 12: Users Information Table (Users) View from the IT Assistant Database Utility Launch the IT Assistant User Interface. A Security Warning dialog box will appear at this point. Proceed by accepting the Security certificate from Dell Computer Corporation. Logon using the “Read/Write” access. (The password should be empty at this point.) Note: Due to the enhanced security settings on the browser for Windows Server 2003, launching the IT Assistant User Interface may bring up an Internet Explorer dialog box. The dialog box talks about Microsoft Internet Explorer’s enhanced security configuration. To not show this message in the future, check the box and click “OK” to close the Internet Explorer dialog box. Figure 13: Internet Explorer’s Dialog Box on Enhanced Security Configuration. Revision Date: 5/5/2017 Page 11 Systems Management Group Figure 14: IT Assistant Logon screen Discovery of Systems using the CIM Protocol: The IT Assistant Network Monitoring and IT Assistant Connection Services are configured to discover devices using various management protocols. The supported protocols are SNMP, DMI, and CIM. CIM is typically used on client systems (e.g., OptiPlex, Dell Precision, and Latitude) that are running OpenManage Client Instrumentation (OMCI) 7.0 or higher. All versions of OpenManage Server Administrator (OMSA) and OMCI 6.1 also support CIM. If you are using the CIM protocol, then the additional steps depicted in Figure 15 are required. If the steps are not performed, IT Assistant may not correctly discover systems using the CIM protocol. Revision Date: 5/5/2017 Page 12 Systems Management Group Figure 15: Steps to Discover Systems through the CIM Protocol. Detailed description of steps: Launch the IT Assistant User Interface on the Management station and login with read/write permissions. From the blue navigation bar, select Options-> Discovery Cycle go to the Discovery Cycle to display the Discovery/Polling Cycle Configuration dialog box. The Discovery/Polling Cycle Configuration dialog box is shown in Figure 16. Enter a password for the User (CIMUser) under the CIM section in the dialog box and click OK. Figure 16: Discovery/Polling Cycle Configuration Dialog Box in IT Assistant Revision Date: 5/5/2017 Page 13 Systems Management Group NOTE: The above changes to the Discovery/Polling Cycle Configuration dialog box affects any discovery ranges added in the future. The following step is required to update the currently configured discovery ranges. From the blue navigation bar, select Options-> Set Discovery Range to display the Discovery Range dialog box. The Discovery Range dialog box is shown in Figure 17. Figure 17: Discovery Range Dialog Box of IT Assistant Click on the Edit button to bring up the Discovery Range Configuration dialog box. Enter a password for the User under the CIM section in the dialog box and click OK. Perform this step on all existing Discovery Ranges. Figure 18: Discovery Range Configuration dialog box of IT Assistant. Revision Date: 5/5/2017 Page 14 Systems Management Group To rediscover instrumented systems through CIM protocol restart the IT Assistant Network Monitoring and IT Assistant Connection Services or perform a forced discovery on all discovery ranges. To restart the IT Assistant services go to the Service Control panel by clicking on Start->Settings->Control Panel->Administrative Tools->Services. In the Service control panel, right click on the IT Assistant Network Monitoring service and select Restart to restart both of the IT Assistant services. To perform a forced discovery of all discovery ranges, from the blue navigation bar, select Management -> Force Discovery. This selection will bring up the Force Discovery dialog box. Select all the discovery ranges listed in the Discovery Range and click “OK” to force discovery. The Force Discovery dialog box is shown in Figure 19. A forced discovery will go through the whole discovery cycle and rediscover systems using the CIM protocol. The amount of time this process takes will vary depending on the number of systems being discovered, network bandwidth, etc. Figure 19: Force Discovery Dialog Box of IT Assistant NOTE: Do not select All Systems in the Force Discovery dialog box because it may not use the updated CIM user name and password for rediscovering the systems. The migration to Windows Server 2003 is now complete. Revision Date: 5/5/2017 Page 15 Systems Management Group Section 3 Installing Dell OpenManage IT Assistant on Windows Server 2003 The sequence of steps required to install (not migrate) IT Assistant on a system with Microsoft Windows Server 2003 is depicted in Figure 20. Each step is explained in detail below. Figure 20: Overview of Steps to Deploy IT Assistant on Windows Server 2003 Install Microsoft Windows Server 2003 on the Management station. Install IT Assistant version 6.4.4 or greater on the system. Verify that the IT Assistant Network Monitoring and IT Assistant Connection Services are running after a reboot. Confirmation that both programs are running can be confirmed by going to the Service Control panel by clicking on Start>Settings->Control Panel->Administrative Tools->Services. Revision Date: 5/5/2017 Page 16 Systems Management Group Figure 21: Service Control Panel Verifying that IT Assistant Services have Started Launch the IT Assistant User Interface. A Security Warning dialog box will appear. Proceed by accepting the Security certificate from Dell Computer Corporation. Login using the “Read/Write” access. A message box will be displayed asking the user if they would like to configure discovery because it has not been configured. Click on “Yes” to configure discovery. Configure the Discovery/Polling Cycle configuration information and click “OK”. By clicking “OK”, the Discovery Range dialog will launch which will allow the user to configure the systems and subnets to be discovered. Once this step is completed, IT Assistant will start discovering systems. Revision Date: 5/5/2017 Page 17 Systems Management Group Section 4 Issues with IT Assistant Following a Migration to Windows Server 2003 If the migration to Microsoft Windows Server 2003 occurs without following the recommended migration steps for IT Assistant, the following problems may occur: Issue: Logging into the IT Assistant User Interface fails. Solution: Launch the IT Assistant database utility dcdbmng. The dcdbmng utility must be executed from the <IT Assistant installation>/bin directory. (The dcdbmng utility is typically located in C:\Program Files\Dell\OpenManage\It Assistant\bin.) Clear the Users Information table (Users) under the ITAssist root node. Restart the IT Assistant User Interface. Note that clearing the Users Information table will clear the authentication information for logging into the ITA user interface. Clearing the authentication information will set the Users Information table to its default value which is an empty string. Log on with “Read/Write” privileges using the default password. Go into the Change IT Assistant Password under Options to reset the password for “Read/Write” to other than the default password. Refer to page 10 of Section 2: Migrating to Windows Server 2003. Issue: Some systems are not discovered. Solution: Re-enter the CIM password from the Discovery Cycle and Set Discovery Range dialogs. Refer to Discovery of Systems using the CIM Protocol of Section 2: Migrating to Windows Server 2003. Issue: SQL Server and IT Assistant services fail to start when system is renamed after migration. Solution: Renaming the system causes SQL Services to fail on restart. This failure is a known issue with MSDE1.0 or SQL Server 7.0. In the case of MSDE1.0, uninstall MSDE1.0 and IT Assistant and then reinstall IT Assistant. In the case of SQL Server 7.0, reinstall SQL Server 7.0 which will perform an upgrade and then uninstall and reinstall IT Assistant. Refer to the “Operating Environment Issues“ section located in ITAssistant 6.4.4 Readme.
