Booting HP-UX in single-user mode 1. Use steps 1-5 from "Booting HP-UX from the UEFI Shell" (page 47) 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 the next step. 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 in LVM maintenance mode is the same as for booting into single-user mode ("Booting HP-UX in single-user mode" (page 48)), except use the -lm boot option instead of the -is boot option: HPUX> boot -lm vmunix Shutting down HP-UX To shut down HP-UX running on a blade: 1. Log on to the OA CLI and enter the CO command to access the system console for your partition. Accessing the console through OA CLI enables you to maintain console access to the partition after HP-UX has shut down. 2. Issue the shutdown command with the appropriate command-line options. The command-line options you specify dictate the way in which HP-UX shuts down, and whether the blade is rebooted. Use the following list to choose an HP-UX shutdown option for your blade: • Shut down HP-UX and halt (power off) the blade using shutdown -h. Reboot a halted blade by powering on the blade using the PC command at the OA CLI Command menu. • Shut down HP-UX and reboot the blade by issuing shutdown -r. For more information, see the shutdown (1m) manpage. 48 Booting and shutting down the operating system

Booting HP-UX in single-user mode
1.
Use steps 1–5 from
“Booting HP-UX from the UEFI Shell” (page 47)
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 the next step.
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

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 in LVM maintenance mode is the same as for booting into
single-user mode (
“Booting HP-UX in single-user mode” (page 48)
), except use the
-lm
boot option
instead of the
-is
boot option:
HPUX> boot -lm vmunix
