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.
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. Press Enter to initiate booting using the chosen boot option.
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.
Procedure 4-4 HP-UX Booting (EFI Shell)
From the EFI Shell environment, to boot HP-UX on a device first access the EFI System Partition
for the root device (for example fs0:) and then enter HPUX to initiate the loader. The EFI Shell
is available only on HP Integrity servers.
Refer to “ACPI Configuration for HP-UX Must Be default” (page 120) for required configuration
details.
1. Access the EFI Shell environment 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.
From the EFI Boot Manager menu, select the EFI Shell menu option to access the EFI Shell
environment.
2. At the EFI Shell environment, issue the acpiconfig command to list the current ACPI
configuration for the local nPartition.
On cell-based HP Integrity servers, to boot the HP-UX OS, an nPartition ACPI configuration
value must be set to default. If the acpiconfig value is not set to default, then HP-UX
cannot boot; in this situation you must reconfigure acpiconfig or booting will be
interrupted with a panic when launching the HP-UX kernel.
To set the ACPI configuration for HP-UX:
a. At the EFI Shell interface enter the acpiconfig default command.
b. Enter the reset command for the nPartition to reboot with the proper (default)
configuration for HP-UX.
3. At the EFI Shell environment, issue the map command to list all currently mapped bootable
devices.
The bootable file systems of interest typically are listed as fs0:, fs1:, and so on.
4. Access the EFI System Partition for the device from which you want to boot HP-UX (fsX:
where X is the file system number).
For example, enter fs2: to access the EFI System Partition for the bootable file system
number 2. The EFI Shell prompt changes to reflect the file system currently accessed.
