Single-User Mode HP-UX Booting
This section describes how to boot HP-UX in single-user mode on cell-based HP 9000 servers
and cell-based HP Integrity servers.
• On HP 9000 servers, to boot HP-UX in single-user mode, refer to “Single-User Mode HP-UX
Booting (BCH Menu)” (page 100) .
• On HP Integrity servers, to boot HP-UX in single-user mode, refer to “Single-User Mode
HP-UX Booting (EFI Shell)” (page 101) .
Procedure 4-5 Single-User Mode HP-UX Booting (BCH Menu)
From the BCH Menu, you can boot HP-UX in single-user mode by issuing the
BOOT
command,
stopping at the ISL interface, and issuing
hpux
loader options. The BCH Menu is available only
on HP 9000 servers.
1. Access the BCH Main Menu for the nPartition on which you want to boot HP-UX in
single-user mode.
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 BCH Main Menu
(the
Main Menu: Enter command or menu>
prompt). If you are at a BCH menu other
than the Main Menu, then enter
MA
to return to the BCH Main Menu.
2. Boot the desired device by using the
BOOT
command at the BCH interface, and specify that
the nPartition stop at the ISL prompt prior to booting (reply
y
to the “stop at the ISL prompt”
question).
Main Menu: Enter command or menu > BOOT 0/0/2/0/0.13
BCH Directed Boot Path: 0/0/2/0/0.13
Do you wish to stop at the ISL prompt prior to booting? (y/n) >> y

3. From the ISL prompt, issue the appropriate Secondary System Loader (
hpux
) command to
boot the HP-UX kernel in the desired mode.
Use the
hpux
loader to specify the boot mode options and to specify which kernel to boot
on the nPartition (for example,
/stand/vmunix
).
• To boot HP-UX in single-user mode:
ISL> hpux -is boot /stand/vmunix
Example 4-1 (page 101) shows output from this command.
• To boot HP-UX at the default run level:
ISL> hpux boot /stand/vmunix
To exit the ISL prompt and return to the BCH interface, issue the
EXIT
command instead
of specifying one of the
hpux
loader commands.
