Option 3: Controller is in a two-node MetroCluster
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
• 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...
Has automatically switched over
Has not automatically switched

with the

command, and the

switchover was vetoed
3. Resynchronize the data aggregates by running the
command from the surviving cluster.
