Steps
1. If the impaired controller is part of an HA pair, disable automatic giveback from the console of the healthy
controller:
storage failover modify -node local -auto-giveback false
2. Take the impaired controller to the LOADER prompt:

Take over or halt the impaired controller:
• For an HA pair, take over the impaired controller from the healthy
controller:
storage failover takeover -ofnode
impaired_node_name
When the impaired controller shows Waiting for giveback…, press
Ctrl-C, and then respond
y
.
• For a stand-alone system:
system node halt
impaired_node_name
3. If the system has only one controller module in the chassis, turn off the power supplies, and then unplug
the impaired controller’s power cords from the power source.
Option 2: Controller is in a MetroCluster
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 the
Administration overview with the CLI
