ONTAP MetroCluster

Verify that the SVMs are running and the aggregates are online

After the switchover is complete, you should verify that the DR partners have taken ownership of the disks and the partner SVMs have come online.

When you run the storage aggregate plex show command after a MetroCluster switchover, the status of plex0 of the switched over root aggregate is indeterminate and is displayed as failed. During this time, the switched over root is not updated. The actual status of this plex can only be determined after the MetroCluster healing phase.

Steps

  1. Check that the aggregates were switched over by using the storage aggregate show command.

    In this example, the aggregates were switched over. The root aggregate (aggr0_b2) is in a degraded state. The data aggregate (b2_aggr2) is in a mirrored, normal state:

    cluster_A::*> storage aggregate show

                                                                   normal

  2. Confirm that the secondary SVMs have come online by using the vserver show command.

    In this example, the previously dormant sync-destination SVMs on the secondary site have been activated and have an Admin State of running:

    cluster_A::*> vserver show
                                          Admin      Operational  Root                 Name    Name
