About this task

Do not place a controller offline unless you are instructed to do so by the Recovery Guru or technical support.

  1. Select Hardware.

  2. If the graphic shows the drives, for DE2000/DE4000/DE6000, click Show back of shelf; for DE6400/DE6600, click Controllers & Components.

    The graphic changes to show the controllers instead of the drives.

  3. Click the controller that you want to place offline.

    The controller’s context menu appears.

  4. Select Place offline, and confirm that you want to perform the operation.


It might take several minutes for System Manager to update the controller’s status to offline. Do not begin any other operations until after the status has been updated.
