In the event the array becomes non-responsive to host commands or you cannot see its disks, you may need to reset the array enclosure hardware. You can reset the array with the power on. The array takes about 1 minute to reset before relinking to the host.
Note - The enclosure may be reset remotely using the Common Array Manager (CAM) software.
Resetting the array is done by pressing a recessed button at the rear of the enclosure (see Enclosure Reset Button Location). The array may also be reset remotely using the Sun Common Array Manager.
Note - This procedure should only be performed after you've checked of other problems at the server and have shut down all server processes that are actively accessing the J4500 array.
The reset process takes about 1 minute. After that, the server should see the array disks.
