Performing a planned failover
You can perform a planned failover to test your disaster recovery configuration or to perform maintenance on the primary cluster.
The relationship must be in sync
Nondisruptive operations must not be running
The ONTAP Mediator must be configured, connected, and in quorum
A planned failover is initiated by the administrator of the secondary cluster. The operation requires switching the primary and secondary roles so that the secondary cluster takes over from the primary. The new primary cluster can then begin processing input and output requests locally without disrupting client operations.
Start the failover operation:
destination::>snapmirror failover start -destination-path vs1_dst:/cg/cg_dst
Monitor the progress of the failover:
destination::>snapmirror failover show
When the failover operation is complete, you can monitor the Synchronous SnapMirror protection relationship status from the destination:
