Issues with reboot

[operadornine]

Hi all ,
I have an IBM 3650 server with redhat 4, im having issue when i try to reboot the server the system is not responding to my commands.
reboot
shutdown -r now

Please any ideas??

Do you get any message at all, or does it just go to the next prompt immediately?

How about in the system logs?

What is the output of who -r (to find out whether it is already trying to transition from one runlevel to another)?

If you run ps -fC rc, can you see any instances of the /etc/rc.d/rc script running?

Does this always happen on this server, or is it just this once (so far)?

Review your grub bootloader!

The way I understood your original question was that you type in reboot or shutdown -r now and nothing happened. Is that right?

Or does the system shut down as expected, and just not boot up again?

no the sistem never reboots, the only way is with the hard reboot, unplug cable power.
And the other just was a question about how to check the process if they are hangup.

thanks..

It's difficult to check whether a process is hanging, unless there's something obvious like it's using 100% CPU. Sometimes if you use strace -p <pid> on a process you can establish whether it is stuck in a system call of some type.

But it would help to identify the cause if you could answer the questions I posted originally.

no sir im still having the issue.

thanks for you help.

 

[Annihilannic]

I know... but you need to post the output of the commands I mentioned above... for example, after you issue a shutdown -r now, what is the output of the who -r command?

[operadornine]

when i do the who -r or ps -fC rc is not showing nothing.
the only way i can reboot is unplugging the power.

thanks

Can you please post the contents of your /etc/inittab file?

Does shutdown -n work?

Annihilannic.

 

[operadornine]

no sir,, did not work.

 

[Annihilannic]

And your /etc/inittab?

How about reboot -f?

yesterday i think i found the issue.
this server has a NFS mount and i removed from the fstab it and did a mount -a. after that i did a shutdown -r now
and is working, i know is strange but i can reboot the server with no problems. Today i will reinstall the nfs/portmaper and see whats going on.

thanks !!
