Log in to the MP of the server. 2. If the component you will power off is assigned to an nPartition, then use the Virtual Front Panel (VFP) to view the current boot state of the nPartition. You must shut down HP-UX on the nPartition before you power off any of the hardware assigned to the nPartition - HP rp7420 | HP 9000 rp7420 Server - User Service Guide, Fifth Edition - Page 85
to power off, use the MP Command menu PS command. The PS command enables you to check the status of the cabinet, system backplane, MP core I/O, PCI power domains-or bricks-in the I/O card cage, and cells. 5.
