User Service Guide, Fifth Edition - HP Integrity rx8640 SEU

Type 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 nPartition, its VFP displays the “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 extensible firmware interface (EFI) shell, then HP-UX has already
been shut down.
• If the nPartition currently is booting, then you should wait for it to reach the EFI shell
and, if necessary, interrupt auto-boot when you see the Attempting to boot and
To discontinue, press any key within 10 seconds messages in the console
window.
NOTE: The message Attempting to boot and To discontinue, press any
key within 10 seconds appears in the console window and not in the VFP.
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
console of the nPartition. If you have no system response at the console, HP-UX may be
halted or hung.
5. Login to HP-UX at the console for the nPartition 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 RS command of MP Command menu to
restart the nPartition. (This enables the nPartition to reset and boot to its EFI shell; if
auto-boot is configured it also boots HP-UX.)
6. Disconnect all the power cords located on the back of the server to remove all power from
the server.
Top Cover Removal
It is necessary to remove the top and side covers (on the left side of the server as you face the
front of the server chassis) to route the cables and to gain access to the backplane.
