Powering Server Cabinets On and Off [Service Processor]
This procedure (Virtual Front Panel, and Command menu’s PE
command) turns a cabinet’s 48-volt power on or off using the service
processor (GSP or MP).
Step 1. Login to the system’s service processor and access the Virtual Front
Panel for the system.
From the service processor Main menu, enter VFP to access the Virtual
Front Panel menu, then enter S to access the “system VFP” that displays
the current status for all nPartitions.
Step 2. Check the VFP status to see whether any cabinet hardware is running
HP-UX.
Any nPartition whose state is “HP-UX heartbeat” is running HP-UX and
thus should not have its hardware powered off until after HP-UX is shut
down.
Step 3. Shut down HP-UX running on any cabinet hardware that you plan to
power off.
Step 4. Confirm that nobody else is using or servicing the cabinet hardware you
plan to power on or off.
You should both physically inspect the hardware, and check whether
others are remotely accessing the system’s service processor (using the
Command menu’s WHO command).
Step 5. Access the system’s service processor Command menu, issue the PE
command, then select the cabinet to power on or power off.
From the service processor Main menu, enter CM to access the Command
menu. To exit the Command menu enter MA.
When using the PE command enter B to power on or off a cabinet; specify
the cabinet number; and then enter ON (power on), OFF (power off), or Q
(quit without changing the power status).
