Overview of the planned failback process
After a planned failover has been accomplished and the original source cluster (cluster A) is ready to take back control of the replication task, you can use the failback feature to release control from the original destination cluster (cluster B) and return it to the original source cluster (cluster A).
For planned failback, run the following command:
Replication> continuous failback fs_name
Where fs_name is the name of the file system which is configured under continuous replication.
Once a planned failback happens, the roles of primary and secondary are switched back to the original state (the pre-failover state). Now, cluster A is the primary site again and cluster B is the secondary site again.
Note:
Planned failback command should be run when both the source and the destination clusters are reachable from each other. It should be run from the destination cluster (which was the original source cluster) and replication should be in progress. If you have NFS/CIFS shares on the source cluster, it is recommended that you should stop the NFS/CIFS server before planned failback.
