User Service Guide, Fifth Edition - HP Integrity rx8640 SEU

2. Log in to the service processor (MP) of the host server.
3. Use the Virtual Front Panel (VFP) to view the current state of the nPartition that you will
shut down.
From the MP Main menu, type VFP to access the Virtual Front Panel menu, and select the
nPartition whose boot state you want to view.
Enter Control-b (^B) to exit the VFP display.
• If an nPartition has booted HP-UX, or if it is in the process of launching HP-UX, you
must shut down HP-UX on the nPartition.
When HP-UX is running on an nPar, its VFP displays “HP-UX heartbeat” with a blinking
asterisk (*) to indicate its interactivity.
In this case, proceed with the next step.
• If the nPartition is at its Boot Console Handler (BCH) interface, then HP-UX has already
been shut down.
• If the nPartition is booting, then you should wait for it to reach the BCH interface and,
if necessary, interrupt auto-boot when you see the “Attempting to boot” and “To
discontinue, press any key within 10 seconds” messages.
If the nPartition is at the BCH menu interface, then HP-UX is shut down. Otherwise, proceed
with the next step to shut down HP-UX.
4. From the MP Main menu, type CO and select the console for the nPartition you plan to shut
down.
You should have access to the HP-UX login prompt (or command line) when using the
nPartition console. If you have no interactivity at the console, HP-UX may be halted or hung.
5. At the nPartition console, log in to HP-UX and shut down the operating system.
After making arrangements with the customer, issue the shutdown command to shut down
and halt HP-UX on the nPartition.
For example, the shutdown -h 240 command will shut down and halt HP-UX on the
nPartition after waiting for a grace period of four minutes (240 seconds).
To reboot the nPartition after it is halted, use the MP Command menu, RS command, to
restart the nPartition. (This enables the nPartition to reset and boot to the BCH interface; if
auto-boot is configured it also boots HP-UX.)
Powering Off Hardware Components
This procedure is for powering off and powering on components that are to be removed and
replaced.
1. Log in to the host server service processor (MP).
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.
HP-UX on the nPartition must be shut down before you power off any of the hardware
assigned to the nPartition.
When you are certain that the nPartition is not running HP-UX, you can power off
components that pertain to the nPartition.
Refer to the procedure, “Shutting Down an nPartition”, for details on determining the
nPartition boot state and shutting down HP-UX.
3. Access the MP Command menu.
From the MP Main menu type CM to access the Command menu.
