Event Summary

This message occurs when a metrocluster switchover operation has failed. The failure could be partial or complete.


Event Log

event log show -event *switchover*

Command Line:

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

metrocluster operation show

Operation: switchover
State: failed
Start Time: xxx
End Time: xxx
Errors: Failed to validate the node and cluster components before the switchover operation.
xxx(non-overridable veto): <Failure reason>


  1. Verify the current state of the metrocluster

metrocluster node show

  1. Check if vservers are online:

vserver show

  1. Follow the recovery steps described in the metrocluster operation show output.
  2. Please contact NetApp Technical Support or log into the NetApp Support Site to create a case. 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 switchover 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
------------------------------------ ------------------- ------------------ ----------

  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 d719de7e-5a23-11ea-93d9-00a0985bd305
      Operation: switchover
          State: failed
         Errors: Failed to validate the node and cluster components before the switchover operation.
