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

successfully: 

metrocluster check lif show
