Cannot shutdown

[KiatLeong Len]

I tried to shutdown my HP 715 machine running on HPUX 10.20 using the following commands:

# shutdown -hy 0
# shutdown -ry 0
# reboot 0

All the above created core file and does not shutdown or reboot the machine. I have to manually power off the machine in order to reboot or shutdown.

What could have caused it? I have checked syslog.log but nothing much there. What other log file can i look into? Or better still, what solution can i take?

Thanks.

Hi,

You can check shutdownlog .
Since after reboot new syslog file created you can check Oldsyslog file..

-Good luck,

Hi,

Try this

To shutdown:

# /sbin/shutdown -h -y 0

To Reboot:

# /sbin/shutdown -r -y 0

Do not use 'reboot 0'

Hi Len,

Try,

shutdown -h 0
shutdown -h now
init 0

Hope this helps.

Regards.

Hi:

Given that you say a core file was created in every case, what does the following return?

# file core

Hi,
Another thought
Check your /sbin/shutdown file.
-r-sr-xr-x 1 root bin 311296 Jun 10 1996 shutdown

What is the bytes size of your shutdown command
(hpux 10.20)

Best of luck

Kiat,

Does it create a core file immediately?
Do you see any shutdown message sequence
on the console??

#which shutdown
-> should show you the binary it is executing. Make sure it's ownership and permissions are correct. Do an ll on it
it see whether it was modified.

Try
#/sbin/shutdown

I had a machine which was supposed to be rebooted each week via cron. At some point (when I wasn't looking) this failed/hung up and stopped subsequent shutdown commands from working. I killed all the old shutdown processes and it was then fine. Never did find out why the first one hung though!!!

Another idea is to try using the init command to change the run level either to 0 for shutdown, or to level 1 or 2 so you can then try your shutdown command again.

Hello,

As James says, see what created the core with "file core". Maybe one of the rc files has a process core dumping and /sbin/rc isn't completing. Check /etc/rc.log and rc.log.old.

When it's core dumping, can you still access the system? Do a ps and see if shutdown and / or rc jobs are running.
