Booting HP-UX
This section covers the following methods of booting HP-UX:
• HP-UX Booting — The standard ways to boot HP-UX. Typically this results in booting
HP-UX in multi-user mode.
• Single-User Mode HP-UX Booting — How to boot HP-UX in single-user mode.
• LVM-Maintenance Mode HP-UX Booting — How to boot HP-UX in LVM-maintenance
mode.
For details on shutting down the HP-UX operating system, see “Shutting Down HP-UX” (page 212).
CAUTION:
ACPI Configuration for HP-UX Must Be “default” On nPartition-capable HP Integrity servers,
to boot the HP-UX operating system an nPartition must have its ACPI configuration value 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 or else booting will be interrupted with a
panic when launching the HP-UX kernel.
To set the ACPI configuration for HP-UX: at the EFI Shell interface enter the acpiconfig
default command, and then enter the reset command for the nPartition to reboot with the
proper (default) configuration for HP-UX.
HP-UX Booting
You can boot HP-UX by using any one of the following procedures:
• “HP-UX Booting [EFI Boot Manager]” (page 205)
The EFI system boot environment is provided on HP Integrity servers.
• “HP-UX Booting [EFI Shell]” (page 206)
The EFI system boot environment is provided on HP Integrity servers.
Procedure E-1 HP-UX Booting [EFI Boot Manager]
From the EFI Boot Manager menu, select an item from the boot options list to boot HP-UX using
the selected boot option.
For required configuration details, see “ACPI Configuration for HP-UX Must Be “default””
(page 205).
1. Access the EFI Boot Manager menu for the nPartition on which you want to boot HP-UX.
a. Login to the MP and enter CO to access the Console list.
b. Select the nPartition 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, select Exit from the sub-menus until
you return to the screen with the EFI Boot Manager heading.
2. At the EFI Boot Manager menu, select an item from the boot options list.
Each item in the boot options list references a specific boot device and provides a specific
set of boot options or arguments to be used when booting the device.
3. To initiate booting using the selected boot option, press Return or Enter.
4. Exit the console and MP interfaces if finished using them.
To exit the EFI environment enter ^B (Control-B); this exits the nPartition console and
returns you to the MP Main Menu. To exit the service processor, enter X at the Main Menu.
