HP Integrity rx7620 Server - User Service Guide, Sixth Edition

This section gives details on how to ensure that the nPartiton is properly shut down, and it also
describes how to power off and on hardware components.
Shutting Down an nPartition
This procedure is for checking an nPartition boot status and, if needed, shutting down HP-UX
on the nPartition.
1. Advise the customer that the system (one or more nPartitions) must be shut down for repairs.
Ensure that the customer has a current backup and inform the customer of the anticipated
downtime.
2. Log in to the MP.
3. Use the Virtual Front Panel (VFP) to view the current state of the nPartition to be shut down.
From the MP Main menu, enter VFP to access the Virtual Front Panel menu, and select the
nPartition whose boot state you want to view.
To exit the VFP display, enter Control-b (^B).
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 nPartition, its VFP displays “HP-UX heartbeat” with a
blinking asterisk (*) to indicate its interactivity.
4. From the MP Main menu, enter 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 might 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 shuts down and halts 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.
Powering Off Hardware Components
To power off individual components or the entire cabinet, follow these steps:
1. Log in to the MP.
2. If the component you will power off is assigned to an nPartition, use the 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. See Appendix D.
When you are certain the nPartition is not running HP-UX, you can power off components
that belong to the nPartition.
For details on determining the nPartition boot state and shutting down HP-UX, see Appendix
D.
3. Access the MP Command menu.
From the MP Main menu, enter CM to access the Command menu.
