4.
Perform the switchback by using the
metrocluster switchback command from any node in the
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
After you replace the part, you can return the failed part to NetApp, as described in the RMA instructions
shipped with the kit. Contact technical support at
NetApp Support, 888-463-8277 (North America), 00-800-44-
638277 (Europe), or +800-800-80-800 (Asia/Pacific) if you need the RMA number or additional help with the
replacement procedure.
Controller module
Replace the controller module - AFF A300
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 an HA pair, the healthy node must be able to take over the node that is being replaced
(referred to in this procedure as the “impaired node”).
• 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 node in a four
or eight node MetroCluster configuration is the same as that in an HA pair. No MetroCluster-specific steps
