The HA state should be the same for all components.
2. If the displayed system state for the chassis does not match your system configuration:
a.
Set the HA state for the chassis:
ha-config modify chassis HA-state
The value for HA-state can be one of the following:
▪
ha
▪
mcc
▪
mcc-2n
▪
mccip
▪
non-ha
b.
Confirm that the setting has changed:
ha-config show
3. If you have not already done so, recable the rest of your system.
4. Reinstall the bezel on the front of the system.
== Step 2: Switch back aggregates in a two-node MetroCluster configuration
After you have completed the FRU replacement in a two-node MetroCluster configuration, you can
perform the MetroCluster switchback operation. This returns the configuration to its normal operating
state, with the sync-source storage virtual machines (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

Ê cluster_B

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
