Shutting down the degraded controller

You can shut down or take over the degraded controller using different procedures, depending on the
storage system hardware configuration.
Shutting down the controller
To shut down the degraded controller, you must determine the status of the controller and, if necessary, take
over that controller so that the healthy controller continues to serve data for the degraded controller's
storage.
Step 1. If the degraded controller is part of an HA pair, disable automatic giveback from the console of the
healthy controller using the following command: storage failover modify -node local -auto-
giveback false
Take the degraded controller to the LOADER prompt by typing halt.
