CommServe Hardware Refresh: Configuring a Cluster Environment

If you moved the CommServe database from a cluster to another cluster, you need to perform the following steps in the new environment.

Before You Begin

  • Log on to both the active and passive nodes of the new cluster environment and ensure that the network details (computer name and IP settings) are properly set.
  • Go the active node of the new cluster environment and copy the Disaster Recovery backup files to the local drive.

    The disaster recovery backup files were saved during the Preparing the Old CommServe Computer for Shutdown procedure.

  • Install the CommServe software in your new cluster environment. During the installation, submit the database dump file that you saved to the local drive.

    For the installation instructions, see Installing Server Packages in a Cluster Environment.

Procedure

Step 1: Convert the CommServe Database from Cluster to Non-Cluster mode

  1. Login to the active node's physical machine in the new cluster and modify the following registry key:
    • HKEY_LOCAL_MACHINE\SOFTWARE\CommVault Systems\Galaxy\Instance001\Machines\<Cluster_Machine_Name>
    • Set value of DWORD registry key bVIRTUALMACHINE to 0.
  2. On the CommServe computer, go to the <software installation path>\Base folder and double-click CSRecoveryAssistant.exe.
  3. In the CommServe Recovery Assistant dialog box, click Recovery, and then click Next.
  4. In the Enter the path to the database dump folder box, enter or browse the name of the Disaster Recovery folder where the dump files are located, and then click Next.

    Make sure that the dump files are available on the local disk of the CommServe host.

  5. In the Enter the path to extract the database files box, type the destination path where you want to restore the CommServe database files and then click Next.

    Alternatively, click Browse and select the restore path.

    By default, all the database files are restored to the CommServe database path located on the destination CommServe host.

  6. In the Summary screen, review the selections, and then click Start Recovery.

    The tool now performs the following operations on the CommServe system:

    • Stop services on your CommServe computer
    • Restore the database to the specified restore path
    • Verifies and upgrades the database if required

      The tool can upgrade the database from a previous version or service pack.

    • Synchronize the CommServe system and the restored database
    • Run post operations on the CommServe computer
  7. When all the operations are complete, click Next.

    The host name and client name of the destination CommServe host and the restored database are displayed. If the names are different, the tool updates the CommServe host with the client name of the restored database and host name of the destination CommServe host.

  8. If the IP address of the destination CommServe host is different from the original production CommServe host, select the Provide a license file check box and enter the path to a new IP address changelicense file in the text box provided and click Next.

    Note: If you do not have a new license, contact your Commvault Account Manager or Support for a new license.

    It is optional to provide a license file if the tool detects no change in the CommServe IP address in the existing license file.

  9. Select the Convert to non-Cluster check box.

    This will remove the cluster related information from the database.

  10. A completion message is displayed. Click Finish.

    The database will be restored and will be converted to a non-cluster mode.

Step 2: Convert the CommServe Database back to Cluster mode

  1. Login to the active node's physical machine in the new cluster and modify the following registry key:
    • HKEY_LOCAL_MACHINE\SOFTWARE\CommVault Systems\Galaxy\Instance001\Machines\<Cluster_Machine_Name>
    • Set value of DWORD registry key bVIRTUALMACHINE to 1.
  2. On the CommServe computer, go to the <software installation path>\Base folder and double-click CSRecoveryAssistant.exe.
  3. In the CommServe Recovery Assistant dialog box, click Recovery, and then click Next.
  4. Select the Database already restored on this computer check box and click Next.
  5. In the Summary screen, review the selections, and then click Start Recovery.
  6. Select the Convert to cluster check box.
  7. In the Physical Node text boxes type the names of the physical CommServe nodes as they appear in the Microsoft Failover Cluster Manager.

    Do not copy and paste the physical node name from the registry, or add the characters "_node" to the node name. The characters "_node" are automatically added to the physical node name during the database restore operation.

  8. A completion message is displayed. Click Finish.

    The database will be converted to the cluster mode.

Step 3: Configure an Additional Setting to Send Update Status to the CommServe

  1. Log on to the CommCell Console.
  2. In the CommCell Browser, right click the <CommServe> computer, and then click Properties.
  3. Click the Additional Settings tab, and then click Add.
  4. In the Add Additional Settings on Windows Client dialog box, do the following:
    1. In the Name box, type bSendUpdateStatusToCS.
    2. In the Category box, type UpdateFlags.
    3. From the Type list, select INTEGER.
    4. In the Value box, type 1.
    5. Click OK.
  5. Click OK to close the CommCell Properties dialog box.
  6. Restart the CommCell services using the Process Manager. For instructions, see Restarting a Service.
