2. Verify that resynchronization is complete on all SVMs: 

metrocluster vserver show

3. Verify that any automatic LIF migrations being performed by the healing operations were completed

successfully: 

metrocluster check lif show

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
--------------------    -------------------     ---------
 Local: 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
--------------------    -------------------     ---------
 Local: 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 8: 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.

Hot-swap a fan module - AFF A400

To swap out a fan module without interrupting service, you must perform a specific
sequence of tasks.

You must replace the fan module within two minutes of removing it from the chassis. System
airflow is disrupted and the controller module or modules shut down after two minutes to avoid
overheating.
