On HP Integrity servers, you can boot to the HP-UX Loader (HPUX.EFI) by using the following procedure.

NOTE: The HP-UX Loader (HPUX.EFI) is available only on HP Integrity servers.

See “Using HP-UX Loader Commands” for details on issuing commands from the HP-UX Boot Loader (HPUX.EFI, the HPUX> prompt).

Procedure 5-51 HPUX.EFI Access: Booting to the HP-UX Loader (EFI Boot Manager or EFI Shell)

The EFI system boot environment is available only on HP Integrity systems.

  1. Access the EFI Shell environment for the nPartition from which you will be running and accessing the HP-UX Loader (HPUX.EFI) interface.

    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 the Exit option from the sub-menus 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. Access the EFI System Partition (fsX: where X is the filesystem number) for the device from which you want to boot HP-UX.

  3. When accessing the EFI System Partition for the desired boot device, issue the HPUX command to invoke the \EFI\HPUX\HPUX.EFI loader on the selected device.

  4. Boot to the HP-UX Boot Loader prompt (HPUX>) by typing any key within the ten seconds given for interrupting the HP-UX boot process. You will use the HPUX.EFI loader to boot HP-UX in single-user mode in the next step.

    After you type a key, the HPUX.EFI interface (the HP-UX Boot Loader prompt, HPUX>) is provided.
