You must verify the HA state of the chassis and return the failed part to NetApp, as described in the RMA instructions shipped with the kit.
Step 1: Verify and set the HA state of the chassis
You must verify the HA state of the chassis, and, if necessary, update the state to match your system configuration.
-
In Maintenance mode, from either controller module, display the HA state of the local controller module and chassis:
ha-config show
The HA state should be the same for all components.
-
If the displayed system state for the chassis does not match your system configuration:
-
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
-
-
Confirm that the setting has changed:
ha-config show
-
-
If you have not already done so, recable the rest of your 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.
-
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.
-
Verify that resynchronization is complete on all SVMs:
metrocluster vserver show
-
Verify that any automatic LIF migrations being performed by the healing operations were completed successfully:
metrocluster check lif show
-
Perform the switchback by using the
metrocluster switchback
command from any node in the surviving cluster. -
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. -
Reestablish any SnapMirror or SnapVault configurations.
Step 3: Complete the replacement process
Return the failed part to NetApp, as described in the RMA instructions shipped with the kit. See the Part Return and Replacements page for further information.
