Upgrading a NetBackup failover server on WSFC cluster
Follow these instructions if you want to upgrade NetBackup.
Note:
NetBackup does not support conversion of an existing non-failover NetBackup server to a failover NetBackup server. Contact Cohesity Technical Support.
Note:
If you have modified NetBackup cluster configuration manually or the configuration has been modified due to external script, make sure that it is reflected correctly in NetBackup cluster registry.
To upgrade a NetBackup failover server on WSFC cluster
- Ensure that a good backup of your cluster environment exists that includes a catalog backup.
- 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.
- Take all NetBackup resources offline except for the disk resource, virtual IP, and virtual name before you begin the upgrade install.
- The upgrade process depends on the release from which you want to upgrade.
- (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.
Start the upgrade.
Make sure all the critical pre-checks are successful including the pre-check db_ping_check.
Follow the instructions for how to upgrade NetBackup in a clustered environment as described in the NetBackup Installation Guide.
The installation program does the following:
Upgrades NetBackup on the active node.
Pushes the install to each inactive node.
Brings the NetBackup resources online.
- (Upgrades from 10.2 and later) Follow the instructions for how to upgrade NetBackup in a clustered environment as described in the NetBackup Installation Guide.
The installation program does the following:
Upgrades NetBackup on the active node.
Pushes the install to each inactive node.
Brings the NetBackup resources online.
- 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.
- Upgrade and configure any options.
Most options require only a license key and do not need to be upgraded separately. For information on how to install and configure a specific option, see the appropriate NetBackup documentation for that option.
