infinite loop in rc script- cannot boot system

[shaick_1]

Hello ,

In HP-UX 11.11 machine, we added new rc script in /sbin/rc3.d/S99xxxx.rc, but accidently there was an infinite loop in the script. So I cannot boot the system.

Also tried to boot in single user mode, but it also runs the rc scripts and HANGs.

Is there any solution to skip the rc script execution in boot up process. Immediate help will be much appreciated.

Thanks,
Mathan.

Hi,

if it's and /sbin/rc3.d script it should not be run when boot into single user mode!
so try again.

hpux -iS

good luck,
Thierry.

Mathan,

get console access.
shutdown -r 0
at BCH main menu interrupt boot and enter
bo pri
answer y when prompted whether to interact with ISL
at ISL promt enter
ISL> hpux -is
wait for # prompt and rename the Start-link
# mv /sbin/rc3.d/S99xxxx.rc /sbin/rc3.d/do_not_use
# reboot

HTH
Regards,
Bernhard

Networking should be set up already by S99xxx in rc3. Have you tried botting multi-uuser and telnetting to the box?

Alternatively, it might be possible to CTRL-C out of the thing.

hi,

there is indeed a key combination to break out of a rc script: but I was guessing at CTRL-Backspace ;-)

Thanks for all your reply, The problem got fixed by booting single user mode.

Initially this method gives same result (hang in rc script ) but I used CTRL+C, CTRL+Backspace before the rc script starts.Now it allow to boot the single user mode.

Once again thanks for the fast reply.
