Booting and Shutting Down HP-UX

Step 1. Access the EFI Shell environment for the nPartition on which you want to boot HP-UX in
LVM-maintenance mode.
Log in to the management processor, and enter CO to access the Console list. Select the nPartition
console.
When accessing the console, confirm that you are at the EFI Boot Manager menu (the main EFI
menu). If you are at another EFI menu, select the Exit option from the submenus until you return
to the screen with the EFI Boot Manager heading.
From the EFI Boot Manager menu, select the EFI Shell menu option to access the EFI Shell
environment.
Step 2. Access the EFI System Partition for the device from which you want to boot HP-UX (fsX: where X
is the file system number).
Step 3. When accessing the EFI System Partition for the desired boot device, issue the HPUX command to
initiate the \EFI\HPUX\HPUX.EFI loader on the device you are accessing.
Step 4. Type any key within the 10 seconds given for interrupting the HP-UX boot process. This stops the
boot process at the HPUX.EFI interface (the HP-UX Boot Loader prompt, HPUX>).
Step 5. At the HPUX.EFI interface, enter the boot -lm vmunix command to boot HP-UX (the
/stand/vmunix kernel) in LVM-maintenance (-lm) mode.
Step 6. Exit the console and management processor interfaces if you are finished using them.
To exit the EFI environment, press
^B (Control+B); this exits the nPartition console and returns to
the management processor Main Menu. To exit the management processor, enter X at the Main
Menu.
Shutting Down HP-UX
When HP-UX is running on an nPartition, you can shut down HP-UX using the shutdown command.
On nPartitions you have the following options when shutting down HP-UX:
• To shut down HP-UX and reboot an nPartition: shutdown -r
On cell-based HP Integrity servers, the shutdown -r command is equivalent to the shutdown -R
command.
• To shut down HP-UX and halt an nPartition: shutdown -h
On cell-based HP Integrity servers, the shutdown -h command is equivalent to the shutdown -R -H
command.
• To perform a reboot for reconfiguration of an nPartition: shutdown -R
• To hold an nPartition at a shutdown for reconfiguration state: shutdown -R -H
For details, refer to the shutdown (1M) manpage.
Shutting Down HP-UX
From the HP-UX command line, issue the shutdown command to shut down the HP-UX OS.
Step 1. Log in to HP-UX running on the nPartition that you want to shut down.
