Change the State of a Volume

Taking a volume offline makes that volume unavailable to initiators. When you set a volume to offline, all current connections are closed.

NOTE: Snapshots are not affected by the online state of a volume.
  1. Choose Manage → Data Storage.
  2. Click the name of the volume to change its status.
  3. Click the ellipsis and select the status that you want to apply to the volume.
    The option that is visible depends upon the current state of the volume or volumes.
After you change the state of the selected volumes, the volumes remain selected. If you do not want to perform an additional operation on these volumes, you should deselect them.
