About this task

Procedure

To restore the primary server in a cluster to a consistent point after a failed upgrade:

Run the onrestorept utility. For more information, see Restoring to a previous consistent state after a failed upgrade.

What to do next

Alternatively, if you backed up your primary server or you prepared for using the High-availability Data Replication (HDR) secondary server as a backup server before you upgraded and the upgrade fails, you can take other steps to restore the cluster. See Restoring a cluster from a backup archive or Restoring a cluster from the HDR secondary server.
