Command Line:

Run the following command on the cluster that attempted to perform the switchover operation.

metrocluster operation show

      Operation: switchback
          State: failed
     Start Time: mm/dd/yyyy hh:mm:ss
       End Time: mm/dd/yyyy hh:mm:ss
         Errors: Failed to validate the node and cluster components before the switchback operation.
                 ClusterA::ClusterA-02 (non-overridable veto): The DR partner is not ready for the switchback operation. Contact technical support for assistance.

Resolution

  1. Verify the status of the remote cluster
    • All nodes should be booted following the completion of healing
  2. Address any issues identified in the Errors section then retry the switchback
  3. Please contact NetApp Technical Support and reference this article for further assistance

Additional Information

Note: The metrocluster operation show output will only report on the last metrocluster operation. If a subsequent metrocluster operation has run since the switchback failure the output will not be relevant to the failure.

To get further details on a previous metrocluster operation:

  1. Run the metrocluster operation history show command to see all previous metrocluster operations:

metrocluster operation history show -fields operation,start-time,state,operation-uuid

  1. From the output, identify the operation-uuid of the failed or partially failed operation:

ClusterA::> metrocluster operation history show -fields operation,start-time,state,operation-uuid
operation-uuid                       operation  start-time          state
------------------------------------ ---------- ------------------  ----------
ce744f8d-3926-11e7-9a03-00a0985bd73d switchback mm/dd/yyyy hh:mm:ss failed
4d33e0bb-3566-11e7-97f2-00a0985bd73d switchback mm/dd/yyyy hh:mm:ss failed

  1. Run the metrocluster operation history show command with the identified operation uuid:

metrocluster operation history show -operation-uuid <operation-uuid>

ClusterA::> metrocluster operation history show -operation-uuid ce744f8d-3926-11e7-9a03-00a0985bd73d
      Operation: switchback
          State: failed
