(SVMs) on the formerly impaired site now active and serving data from the local disk
pools.

This task only applies to two-node MetroCluster configurations.

Steps

1. Verify that all nodes are in the

enabled

state:

metrocluster node show

cluster_B::> metrocluster node show

DR Configuration DR
Group Cluster Node State Mirroring Mode
----- ------- -------------- -------------- ---------
--------------------
1 cluster_A
controller_A_1 configured enabled heal roots
completed
cluster_B
controller_B_1 configured enabled waiting for
switchback recovery
2 entries were displayed.

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.:
