surviving cluster.
5.
Verify that the switchback operation has completed:
metrocluster show
The switchback operation is still running when a cluster is in the waiting-for-switchback state:
cluster_B::> metrocluster show
Cluster Configuration State Mode
-------------------- ------------------- ---------
ÊLocal: cluster_B configured switchover
Remote: cluster_A configured waiting-for-switchback
The switchback operation is complete when the clusters are in the normal state.:
cluster_B::> metrocluster show
Cluster Configuration State Mode
-------------------- ------------------- ---------
ÊLocal: cluster_B configured normal
Remote: cluster_A configured normal
If a switchback is taking a long time to finish, you can check on the status of in-progress baselines by using
the
metrocluster config-replication resync-status show command.
6. Reestablish any SnapMirror or SnapVault configurations.
Step 4: Return the failed part to NetApp
Return the failed part to NetApp, as described in the RMA instructions shipped with the kit. See the Part Return
& Replacements
page for further information.
Controller module
Overview of controller module replacement - AFF C400
You must review the prerequisites for the replacement procedure and select the correct
one for your version of the ONTAP operating system.
• All drive shelves must be working properly.
• If your system is in a MetroCluster configuration, you must review the section
Choosing the correct
recovery procedure
to determine whether you should use this procedure.
If this is the procedure you should use, note that the controller replacement procedure for a controller in a
four or eight node MetroCluster configuration is the same as that in an HA pair. No MetroCluster-specific
steps are required because the failure is restricted to an HA pair and storage failover commands can be
used to provide nondisruptive operation during the replacement.
• You must replace the failed component with a replacement FRU component you received from your
provider.
