  • Page 99 Option 1: Most configurations To shut down the impaired node, you must determine the status of the node and, if necessary, take over the node so that the healthy node continues to serve data from the impaired node storage. About this task If you have a cluster with more than two nodes, it must be in quorum.
  • Page 100 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.
