Booting HP-UX
This section describes the following methods of booting HP-UX:
• “Standard HP-UX Booting” (page 96) — The standard ways to boot HP-UX. Typically, this
results in booting HP-UX in multiuser mode.
• “Single-User Mode HP-UX Booting” (page 100) — How to boot HP-UX in single-user mode.
• “LVM-Maintenance Mode HP-UX Booting” (page 102) — How to boot HP-UX in
LVM-maintenance mode.
Refer to “Shutting Down HP-UX” (page 103) 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.

only on 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 Main Menu
(the

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
also can use the
SEARCH
command to find and list potentially bootable devices for the
nPartition.
