For details on shutting down the HP-UX operating system, see “Shutting Down HP-UX” (page 214).
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, HP-UX cannot boot. In this
situation, you must reconfigure acpiconfig or booting is 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 207)
The EFI system boot environment is provided on HP Integrity servers.
• “HP-UX Booting [EFI Shell]” (page 208)
The EFI system boot environment is provided on HP Integrity servers.
Procedure D-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 207).
1. Access the EFI Boot Manager menu for the nPartition on which you want to boot HP-UX.
Login to the service processor (MP or GSP) and enter CO to access the Console list. Select
the nPartition console.
When accessing the console, confirm that you are at the EFI Boot Manager menu (the main
EFI menu). If 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 service processor interfaces when finished using them.
To exit the EFI environment, enter ^B (Control-B); this exits the nPartition console and
returns to the service processor Main Menu. To exit the service processor, enter X at the
Main Menu.
