HP-UX Booting (EFI Shell)

details.
Step 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.

environment.
Step 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.
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.
Step 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.
Step 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.
The EFI Shell prompt changes to reflect the file system currently accessed.
The file system number can change each time it is mapped (for example, when the nPartition boots,
or when the map -r command is issued).
or when the map -r command is issued).
Step 5. When accessing the EFI System Partition for the desired boot device, issue the HPUX command to
initiate the HPUX.EFI loader on the device you are accessing.
The full path for the loader is \EFI\HPUX\HPUX.EFI. When initiated, HPUX.EFI references the
\EFI\HPUX\AUTO
\EFI\HPUX\AUTO
file and boots HP-UX using the default boot behavior specified in the AUTO file.
You are given 10 seconds to interrupt the automatic booting of the default boot behavior. Pressing
any key during this 10-second period stops the HP-UX boot process and enables you to interact
with the HPUX.EFI loader. To exit the loader (the HPUX> prompt), enter exit (this returns you to the
EFI Shell).
