If an Advanced Disk-based backup failed due to the application virtual server failover, you may need to re-join the cluster disk groups.
To manually re-join the two cluster disk groups and resynchronize the volumes
-
Import the cluster disk group into the node, if the original cluster disk group is not already imported into the node where the production virtual server is currently online.
-
Rejoin the new cluster disk group with the original cluster disk group.
-
Snap back the snapped volumes with their original volumes. Ensure that the option to synchronize using the original volume is selected.
If you are not able to import the new cluster disk group into the node where the original cluster disk group is currently located, failover the application virtual server back to its original node before rejoining the two cluster disk groups.
