Should you need to restart the entire switch, you can use the managementreset command. Resetting the entire switch disrupts the InfiniBand fabric. All services are reinitialized and all links will retrain. Perform this task only when absolutely necessary.
Note - By rebooting the management controller, the link to the management console is severed. You must reaccess the management controller to regain administrative control.
