You can shut down or take over the impaired controller using different procedures, depending on the storage system hardware configuration.
Choices
Completing node shutdown
After completing the NVE or NSE tasks, you need to complete the shutdown of the impaired node.
Shutting down a node in a two-node MetroCluster configuration
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.
