HP Integrity rx8640, HP 9000 rp8440 Server User Service Guide

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 nPartiton
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 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 7–1 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.
See the hpux (1M) manpage for a detailed list of hpux loader options.
