Reboot command

[Tim O'Connell]

Hi,

I haven't rebooted my RP5430 HPUX server for about 3 years. I went to shut it down today to connect up a new tape drive & it kept rebooting. It never shutdown . I used the command I had in my notes - shutdown -h 0 . Is there something I have left out?.

Thanks,

Tim

Hi,

Thanks for the replies.

I used shutdown -h 0 but the server just rebooted & came back up.
Would shutdown -hy 0 have shut it down completely?

Thanks,

Tim

yeah "shutdown -hy 0" will halt down your systems. If you want to completely power off the server then you need to down the power from MP/GSP console.

Tim,

No, adding the y switch causes an automatic "yes" response for any interactive input during the shutdown. It would have no effect on whether the machine reboots or not - that is strictly controlled by the -h vs the -r switch.

I would think there must be some sort of message indicating why the machine is rebooting. Perhaps it has a problem during shutdown and the failure causes a reboot? Study the output from the shutdown process carefully and see if there isn't some indication of why this is happening.

Hi Tim,

I normally always use:

shutdown -yh 0

Which is a shutdown halt (-h) with no grace period and answering yes (-y) to any interactive questions from the shutdown process.

Your system should have been halting. What output is on the console during the shutdown, especially the point where it starts to then boot again?

I don't have the output now but I will need to shutdown the server again as the tape drive wasn't picked up & will keep an eye on it. On older Unix servers there used to be a /var/log/console - is there similar on HPUX?

Thanks,

Tim

>there used to be a /var/log/console - is there similar on HP-UX?

No. But sometimes the MP/GSP console logs may have 100s of lines.

Have you looked at syslog and /etc/shutdownlog?
