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 Integrity servers.
On HP Integrity servers, to boot HP-UX use either of the following procedures:
• “HP-UX Booting (EFI Boot Manager)” on page 147
• “HP-UX Booting (EFI Shell)” on page 148
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
that boot option. The EFI Boot Manager is available only on HP Integrity servers.
Refer to “ACPI Configuration for HP-UX Must Be default” on page 147 for required configuration
details.
Step 1. Access the EFI Boot Manager 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 EFI Boot Manager menu (the main EFI
menu). If you are at another EFI menu, select the Exit option from the submenus until you return
to the screen with the EFI Boot Manager heading.
Step 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.
Step 3. Press Enter to initiate booting using the chosen boot option.
Step 4. Exit the console and management processor interfaces if you are finished using them.
To exit the EFI environment, press ^B ( Control+B ); this exits the nPartition console and returns to
the management processor Main Menu. To exit the management processor, enter X at the Main
Menu.
