NetApp AFF A Series User Manual

Do not use this procedure if your system is in a two-node MetroCluster configuration.
To shut down the impaired controller, you must determine the status of the controller and, if necessary, take
over the controller so that the healthy controller continues to serve data from the impaired controller storage.
• If you have a cluster with more than two nodes, it must be in quorum. If the cluster is not in quorum or a
healthy controller shows false for eligibility and health, you must correct the issue before shutting down the
impaired controller; see
Synchronize a node with the cluster.
• If you have a MetroCluster configuration, you must have confirmed that the MetroCluster Configuration
State is configured and that the nodes are in an enabled and normal state (
metrocluster node show).
