- All nodes should be booted following the completion of healing
- Address any issues identified in the Errors section then retry the switchback

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:
- Run the metrocluster operation history show command to see all previous metrocluster operations:
metrocluster operation history show -fields operation,start-time,state,operation-uuid
- 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
