Issue

Switchback is failing after an unexpected switchover.

Metrocluster Operation Show reports:

ClusterA::> metrocluster operation show
  Operation: switchback
      State: failed
 Start Time: dd/mm/yyyy hh:mm:ss
   End Time: dd/mm/yyyy hh:mm:ss
     Errors: Failed to set up the node and cluster components for the switchback operation.
             ClusterA (fatal): The MetroCluster DR operation was terminated because the online status of the replication units in the cluster could not be verified. Run the (privilege: advanced) "cluster ring show" command to display the status of the replication units. Try the MetroCluster DR operation again when each replication unit's "online" field shows either "master" or "secondary".
