If your system is running
ONTAP…
Then…
With two nodes in the cluster
Issue these commands:
node::> cluster ha modify
-configured true``node::> storage failover modify
-node node0 -enabled true
With more than two nodes in the
cluster
Issue this command:
node::> storage failover modify
-node node0 -enabled true
In a two-node MetroCluster
configuration
Proceed to the next step. The MetroCluster switchback procedure is
done in the next task in the replacement process.
In a stand-alone configuration
You have no further steps in this particular task. You have completed
system-level diagnostics.
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
