Booting HP-UX in single-user mode
Procedure
1. Use steps 1–5 from Booting HP-UX from the UEFI Shell on page 39 to access the UEFI shell and
launch the HPUX.EFI loader.
2. Access the HP-UX Boot Loader prompt (HPUX>) by pressing any key within the 10 seconds given for
interrupting the HP-UX boot process. Use the HPUX.EFI loader to boot HP-UX in single-user mode in
step 3.
After you press a key, the HPUX.EFI interface (the HP-UX Boot Loader prompt, HPUX>) launches. For
help using the HPUX.EFI loader, enter the help command. To return to the UEFI Shell, enter exit.
3. At the HPUX.EFI interface (the HP-UX Boot loader prompt, HPUX>) enter the boot -is vmunix
command to boot HP-UX (the /stand/vmunix kernel) in single-user (-is) mode.
Booting HP-UX in LVM-maintenance mode
The procedure for booting HP-UX into LVM Maintenance Mode is the same as for booting into single user
mode (Booting HP-UX in single-user mode on page 40), except use the -lm boot option instead of the
-is boot option:
HPUX> boot -lm vmunix
Shutting down HP-UX
For more information, see the shutdownvolume(1M) manpage.
Procedure
1. Log in to HP-UX running on the server that you want to shut down or log in to iLO 3 MP for the server
and use the Console menu to access the system console. Accessing the console through iLO 3 MP
enables you to maintain console access to the server after HP-UX has shut down.
2. Issue the shutdown command with the appropriate command-line options.
The command-line options you specify determines the way in which HP-UX shuts down and whether
the server is rebooted.
Use the following list to choose an HP-UX shutdown option for your server:
a. Shut down HP-UX and halt (power off) the server using the shutdown -h command.
Reboot a halted server by powering on the server using the PC command at the iLO 3 MP
Command menu.
b. Shut down HP-UX and reboot the server by issuing the shutdown -r command.
