ONTAP 9.15.1 commands

The snapmirror set-preferred-cluster sets the local cluster as the preferred cluster for SnapMirror active sync relationships of policy-type 'automated-failover-duplex'. Note that the 'preferred-cluster' will be the one serving IO upon scenarios like a network partition between primary and secondary.

You should execute the snapmirror set-preferred-cluster command from the destination cluster.

Make sure the relationship status is InSync and the ONTAP Mediator is configured, connected, and in quorum before using this command.

To perform a set-preferred-cluster operation of an SnapMirror active sync relationship with source Consistency Group cg_src in Vserver vs1.example.com , and the destination Consistency Group cg_dst in Vserver vs2.example.com , type the following command from the destination cluster:

Note: The SnapMirror set-preferred-cluster operation internally triggers a planned failover operation. Hence, the SnapMirror active sync relationship information in the snapmirror show command will now be available on the new destination that is Vserver vs2.example.com with cg_dst as the new source and cg_src as the new destination Consistency Groups after the SnapMirror set-preferred-cluster operation is completed.
