NetBackup™ Clustered Primary Server Administrator's Guide

To upgrade a NetBackup failover server

1. Ensure that a good backup of your cluster environment exists that includes a catalog backup.

2. For each NetBackup server that runs outside of the cluster, ensure that the server list is accurate. This list should contain the name of each node where NetBackup can run and the name of the virtual server.
3. Take the VCS NetBackup cluster resource offline before you begin the upgrade.

   Note:

   Make sure that shared disk and IP resources are online during the upgrade on active node.

4. Enable the VCS configuration in read and write mode with haconf -makerw
5. Freeze the NetBackup group using the following command:

   hagrp -freeze <nbu_group_name> -persistent
   

6. Stop the NetBackup cluster agent on all nodes of the NetBackup Group using the following command:

   haagent -stop NetBackup -force -sys <node>

7. The upgrade process depends on the release from which you want to upgrade.

   • For upgrades from NetBackup 10.1.1 and earlier, continue with step 8.

   • For upgrades from NetBackup 10.2 and later, continue with step 9.

8. (Upgrades from 10.1.1 and earlier) Perform the following steps:

   • Follow the instructions for how to upgrade NetBackup in a clustered environment as described in the following article.

     https://www.veritas.com/support/en_US/article.100055395

   • Make sure all the critical pre-checks are successful including the pre-check db_ping_check.

   • On the active node, install the NetBackup server software.

     Follow the instructions for how to upgrade NetBackup as described in the NetBackup Installation Guide.

     If required to specify the server name, provide the virtual name of the server.

9. (Upgrades from 10.2 and later) On the active node, install the NetBackup server software.

   Note the following:

   • Follow the instructions for how to upgrade NetBackup as described in the NetBackup Installation Guide.

     https://www.veritas.com/docs/DOC5332

   • If required to specify the server name, provide the virtual name of the server.

10. On each inactive node to which NetBackup may fail over, install the NetBackup server software.

    Note the following:

    • Follow the instructions for how to upgrade NetBackup as described in the NetBackup Installation Guide.

    • If required to specify the server name, provide the virtual name of the server.

11. Post upgrade installation, verify if the security certificates are deployed on all the nodes within the cluster. If not, generate security certificates on all the nodes within the cluster.

    For more information on deploying a certificate in a clustered NetBackup setup, see the NetBackup Security and Encryption Guide.

12. Start the VCS NetBackup cluster agent on all nodes of the NetBackup Group. Use the following command:

    haagent -start NetBackup -sys <node>

13. Enable the VCS configuration in read and write mode with haconf -makerw
14. Unfreeze the NetBackup group using the following command:

    hagrp -unfreeze <nbu_group_name> -persistent
    

15. Enable the VCS configuration in read-only mode with haconf -dump -makero
16. Take the NetBackup group offline and then bring online.
17. On each node where NetBackup server is installed, upgrade NetBackup options.

18. Verify that NetBackup can failover properly in the cluster.
