LVM Maintenance Mode HP-UX Booting
Use the following procedure to boot HP-UX in Logical Volume Management (LVM) maintenance mode.
Booting HP-UX in LVM-Maintenance Mode (EFI Shell)
From the EFI Shell environment, boot in LVM-maintenance mode by stopping the boot process at the
HPUX.EFI interface (the HP-UX Boot Loader prompt, HPUX>) and entering the boot -lm vmunix command.
Step 1. Access the EFI Shell environment for the server on which you want to boot HP-UX in
LVM-maintenance mode.
Log in to the iLO MP and enter CO to choose the system 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, choose the
Exit option from the submenus until you return
to the screen with the EFI Boot Manager heading.
From the EFI Boot Manager menu, choose the
EFI Shell menu option to access the EFI Shell
environment.
Step 2. Access the EFI System Partition (fs
X
: where
X
is the file system number) for the device from which
you want to boot HP-UX.
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. Press 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 iLO MP interfaces when finished using them.
Press
Ctrl+B to exit the system console and return to the iLO MP Main Menu. To exit the iLO MP,
enter X at the Main Menu.
Shutting Down HP-UX
To shut down HP-UX running on a server, use the shutdown command. You have the following options when
shutting down HP-UX:
• To shut down and reboot an HP-UX server, use the shutdown -r command.
• To shut down and halt (power off) an HP-UX server, use the shutdown -h command.
For details see the shutdown (1M) manpage and the following procedure:
Shutting Down HP-UX (/sbin/shutdown Command)
From the HP-UX command line, issue the shutdown command to shut down the HP-UX operating system.
Step 1. Log in to HP-UX running on the server that you want to shut down.
You should log in to the iLO MP for the server and use the Console menu to access the system
console. Accessing the console through the iLO MP enables you to maintain console access to the
server after HP-UX has shut down.
Step 2. Issue the shutdown command with the appropriate command-line options.
