Booting the System
HP-UX version 11.00.03 Starting and Stopping the System 3-19
Manually Booting Your System
Normally, booting occurs automatically at the appropriate times, for example,
when the system powers up. However, certain events could require you to initiate
a manual boot, for example, if the system cannot find the boot device or a system
problem makes the boot device unusable. Use the following procedure for the
manual boot process:
1. If the PROM: prompt is displayed on the system console, proceed to step 2. If
you wish to force a manual boot, invoke the appropriate command:
– If you are on a running system, either invoke SAM (see “Shutting Down
the System”) or enter
shutdown -h
When the system halts, invoke the console command menu (press the
<F5>
key on a V105 console or usually the
<Break> key on other console terminals)
and enter the reset_bus command. See “Issuing Console Commands”
for more information.
– If the system is in the automatic boot process, press any key when you see
the following prompt:
Hit any key to enter manual boot mode, else wait for autoboot
hpmc_reset
Issues a high priority machine check (HPMC) to all CPUs on
all CPU/memory boards in the system. This command first
flushes the caches to preserve dump information and then
(based on an internal flag value) either invokes a “warm”
reset (that is, reboots the system, saving current memory
and registers) or simply returns to the HP-UX operating
system.
