Booting HP-UX in Single-User or
LVM-Maintenance Mode
You can boot HP-UX in single-user mode or LVM-maintenance mode. To
do this use the BCH interface to boot the desired device, and use the
Initial System Loader (ISL) and the Secondary System Loader (hpux) to
specify the options for booting HP-UX in the desired mode.
See the hpux (1M) manpage for details on options for other boot modes.
BCH, ISL, and
hpux
Use the following procedure to boot HP-UX in single-user mode or
LVM-maintenance mode on a partition.
Step 1. Log in to the Superdome complex’s GSP, access the partition’s console,
and access the BCH main menu.
From the partition console you access the partition’s BCH interface. If
the partition is not at the BCH interface you must either boot the
partition or shut down HP-UX to return to the BCH interface.
Step 2. Boot the desired device using the BCH interface’s BOOT command, and
specify that the partition stop at the ISL prompt prior to booting.
Step 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 partition.
You can perform this task using the BCH interface and the ISL
and hpux loaders.
