HP-UX System Administrator's Guide: Routine Management Tasks

1. Access the EFI Shell environment for the nPartition on which you want to boot

HP-UX in single-user mode.

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. Make sure the selected boot device is the one that contains the kernel file you want

to boot from. If you are not sure:

a. Enter map at the EFI shell prompt to list bootable devices on your system.

The devices will be listed with entries that begin with fs#: (where # is a

number such as 0, 1, 2, 3, etc.). For example:

fs0 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Primary,Master)/HD(Part1,Sig88F40A3A-B992-11E1-8002-D6217B60E588)

fs1 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Primary,Master)/HD(Part3,Sig88F40A9E-B992-11E1-8004-D6217B60E588)

blk0 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Primary,Master)

blk1 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Primary,Master)/HD(Part1,Sig88f40A3A-B992-11E1-8002-D6217B60E588)

blk2 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Primary,Master)/HD(Part1,Sig88f40A6C-B992-11E1-8003-D6217B60E588)

blk4 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Secondary,Master)

If the map command shows a lot of devices you can use the -b option to make

it show the output one screen at a time.

b. Determine which entry maps to the device containing the kernel file you are

trying to boot from, and enter the fs#: name at the shell prompt.

For example, if the entry for the device you want (from a list that is longer

than the above example) is tagged as “fs7:”, enter fs7: at the shell prompt:

Shell> fs7:

The device associated with entry fs7: is now the selected boot device.

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. For help using the HPUX.EFI loader, type the help command.

To return to the EFI Shell, type exit.
