If your system is running
ONTAP… Then…
Resulted in some test failures Determine the cause of the problem.
a. Exit Maintenance mode:
halt
b. Perform a clean shutdown, and then disconnect the power
supplies.
c. Verify that you have observed all of the considerations identified
for running system-level diagnostics, that cables are securely
connected, and that hardware components are properly installed
in the storage system.
d. Reconnect the power supplies, and then power on the storage
system.
e. Rerun the system-level diagnostics test.
Step 3: 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
----- ------- -------------- -------------- ---------
--------------------
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
