Changing the Owner of a Volume (LSI, CLARiiON and Sun 6130)
When a volume is created, the management server automatically assigns a controller to be the owner of the volume. You can change the owning controller if you want to use a different controller for LUN masking.
NOTE: If the owner becomes unreachable as a result of a network failure or the owner itself fails, the other controller in the pair automatically becomes the owner of the volume.
To change the owner:
1.Click the Edit (
) button for the volume you want to modify.
2.Select the owner for the volume from the Current Owner menu.
3.Click OK.
