Overview of the planned failover process

Consider two Access Appliance clusters, cluster A and cluster B. Here, cluster A is the original source cluster that replicates data to cluster B which is the original destination cluster. If the source cluster A is taken down for routine maintenance or for moving applications to cluster B, you can use a planned failover operation so that the replication direction switches from cluster B (new source) to cluster A (new destination). You should perform the planned failover before cluster A is taken down.

For planned failover, run the following command on the source cluster (cluster A):

Replication> continuous failover fs_name

Where fs_name is the name of the file system which is configured under continuous replication.

Once a planned failover happens, the roles of primary and secondary are switched. It will online the file system at new primary site and offline the file system at new secondary site. Now, cluster B is the primary site and cluster A is the secondary site. The file systems come online at the new primary site (cluster B) and the file systems at new secondary site (cluster A) are offline.
