Option 3: Controller is in a two-node Metrocluster
After completing the NVE or NSE tasks, you need to complete the shutdown of the impaired node.
To shut down the impaired node, you must determine the status of the node and, if
necessary, switch over the node so that the healthy node continues to serve data from
the impaired node storage.
About this task
• If you are using NetApp Storage Encryption, you must have reset the MSID using the instructions in the
"Returning SEDs to unprotected mode" section of
Administration overview with the CLI.
• You must leave the power supplies turned on at the end of this procedure to provide power to the healthy
node.
Steps
1. Check the MetroCluster status to determine whether the impaired node has automatically switched over to
the healthy node:
metrocluster show
2. Depending on whether an automatic switchover has occurred, proceed according to the following table:
If the impaired node… Then…
Has automatically switched over Proceed to the next step.
Has not automatically switched
over
Perform a planned switchover operation from the healthy node:
metrocluster switchover
Has not automatically switched
over, you attempted switchover
with the
metrocluster
switchover
command, and the
switchover was vetoed
Review the veto messages and, if possible, resolve the issue and try
again. If you are unable to resolve the issue, contact technical
support.
3.
Resynchronize the data aggregates by running the
metrocluster heal -phase aggregates
command from the surviving cluster.
controller_A_1::> metrocluster heal -phase aggregates
[Job 130] Job succeeded: Heal Aggregates is successful.
If the healing is vetoed, you have the option of reissuing the metrocluster heal command with the
-override-vetoes parameter. If you use this optional parameter, the system overrides any soft vetoes that
prevent the healing operation.
4. Verify that the operation has been completed by using the metrocluster operation show command.
