device of the host running the controller.
3. Click Use Command Devices.
NOTE:
The controller communicates with the XP and P9500 disk arrays through the command device
names stored in the controller. HP recommends that you add more than one command device
to enable the controller to use an alternative command device, if required.
After you set command devices for a P9500 disk array, the MP blades associated with the selected
P9500 disk array gets displayed on the DLOM Settings screen and the MP blade utilization data
is plotted on the MPB graphs screen.
For more information on specifying DLOM settings, see “Specifying DLOM settings” on page 59.
For more information on MP blade utilization, see “MPB graphs screen” on page 73.
