Booting HP-UX
This section describes the following methods of booting HP-UX:
• “Standard HP-UX Booting” (page 88) — The standard method to boot HP-UX. Typically, this
results in booting HP-UX in multiuser mode.
• “Single-User Mode HP-UX Booting” (page 91) — How to boot HP-UX in single-user mode.
• “LVM-Maintenance Mode HP-UX Booting” (page 94) — How to boot HP-UX in LVM-maintenance
mode.
See “Shutting Down HP-UX” (page 95) for details on shutting down the HP-UX OS.
CAUTION:
ACPI Configuration for HP-UX Must Be default
On cell-based HP Integrity servers, to boot the HP-UX OS, an nPartition ACPI configuration value
must be set to default.
At the EFI Shell interface, enter the acpiconfig command with no arguments to list the current
ACPI configuration. If the acpiconfig value is not set to default, then HP-UX cannot boot. In
this situation you must reconfigure acpiconfig; otherwise, booting will be interrupted with a
panic when the HP-UX kernel is launched.
To set the ACPI configuration for HP-UX:
1. At the EFI Shell interface, enter the acpiconfig default command.
2. Enter the reset command for the nPartition to reboot with the proper (default) configuration
for HP-UX.
Standard HP-UX Booting
This section describes how to boot HP-UX on cell-based HP 9000 servers and cell-based HP Integrity
servers.
• On HP 9000 servers, to boot HP-UX, see “HP-UX Booting (BCH Menu)”
• On HP Integrity servers, to boot HP-UX, use either of the following procedures:
— “HP-UX Booting (EFI Boot Manager)” (page 90)
— “HP-UX Booting (EFI Shell)” (page 90)
Procedure 2 HP-UX Booting (BCH Menu)
From the BCH Menu, use the boot command to boot the HP-UX OS. The BCH Menu is available
only on the HP 9000 servers.
1. Access the BCH Main Menu for the nPartition on which you want to boot HP-UX.
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 BCH Menu (the
Main Menu: Enter command or menu> prompt). If you are at a BCH menu other than
the Main Menu, then enter ma to return to the BCH Main Menu.
2. Select which device to boot.
From the BCH Main Menu, use the path command to list any boot path variable settings.
The primary (PRI) boot path normally is set to the main boot device for the nPartition. You can
also use the search command to find and list potentially bootable devices for the nPartition.
