Booting the System

2. The system displays a PROM: prompt. At this prompt, invoke the primary
bootloader. To do this, enter
PROM: boot location
location is the boot device location.
Enter a flash card location from which to boot. For example, to boot from the
flash card in card-cage 2, enter
PROM: boot 2
For a list of PROM commands, enter help at the PROM: prompt. For more
information, see “CPU PROM Commands.”
3. Once the system finds the boot device, it loads the primary bootloader and
displays the lynx$ prompt. To invoke the secondary bootloader (see
“Primary Bootloader Commands” for options), enter
lynx$ boot
4. The following message appears:
ISL: Hit any key to enter manual boot mode, else wait for autoboot
If you do not press a key, the boot process continues without further
prompting. If you press a key (during the wait period), the secondary
bootloader prompt (ISL>) appears.
5. To complete the manual boot process (see “Secondary Bootloader
Commands” for options), enter
ISL> hpux boot
From this point, the boot process continues without interruption. The system
displays various messages as the boot progresses until the system is brought
up to the appropriate run-level.
Restoring and Booting from a Backup Tape
The make_boot_image utility is used in conjunction with the make_recovery
tool provided with the HP-UX Ignite-UX facility. It creates a special flash card to
use when booting a system before recovering the root disk from a recovery tape
made with the make_recovery utility. A special boot image is needed because of
differences in the traditional HP-UX operating system and the Continuum system
boot process.
The recovery tape is made according to the HP-UX operating system instructions
for using the make_recovery utility. It archives an image of the root disk to tape.
This image can be used to quickly restore the root disk in case of failure. The
recovery tape should be updated whenever changes are made that affect the root
disk.
