Reset (reboot) controller
Some issues require a controller reset (reboot). You can reset the controller even if you don’t have physical access to it.
Before you begin
The storage array must have two controllers. The controller that you are not resetting must be online (in the optimal state).
Make sure that no volumes are in use or that you have a multipath driver installed on all hosts using these volumes.
If the graphic shows the drives, click Show back of shelf.
The graphic changes to show the controllers instead of the drives.
Click the controller that you want to reset.
The controller’s context menu appears.
Select Reset, and confirm that you want to perform the operation.
