rc script hung on bootup

John Peace — Thu, 04 Dec 2003 07:31:13 GMT

K580
HP-UX 11.0

The server is located 6 hours away. I administer it remotely. I have someone at the site that can "turn the key" on.

Problem:

The server went down hard. There was a power outage at the site. When the server was turned back on, it started its boot process. It is hung after /sbin/rc2.d/S742diagnostic. The next script is /sbin/rc2.d/S744predictive.

I have checked the syslog and tombstones files. I can find no errors. Where else can I look? I only boot up to run level 2. I have a database package running, and 50 people connected. I have already planned a reboot later tonight.

What can I do to research the problem?

To start with, search for child processes of the script by doing "ps -ef | grep "
and then of all the found subprocesses, so you know what command hangs.

Do you have access to the console? Perhaps it is waiting for some user-input or the buffer of your console driver is full...

Just check /etc/rc.log.

check the STm logs

/var/stm/logs/os

Try stating manually the /usr/sbin/stm/uut/bin/sys/diagmond

This should start other services

When you have a reboot later tonight, Boot into single user mode, move sbin/rc2.d/S742diagnostic to sbin/rc2.d/TS742diagnostic. This will stop diagnostics.

When booted, try starting it manually and check. Also check if you are upto date on STM.

No access to the console.

I had already checked the rc.log This is the tail of it:

# tail rc.log
----------------------------
cron started

Support Tools Informational Fileset
Output from "/sbin/rc2.d/S740supprtinfo start":
----------------------------

Start diagnostic subsystem
Output from "/sbin/rc2.d/S742diagnostic start":
----------------------------

Thats as far as it got. I will check patches. I am pretty sure I am up to date on this server ( I have 10 all configured the same). I will rename the startup tonight and manually start it.

I renamed S742diagnostic, rebooted machine. Came up fine. I manually ran /sbin/init.d/diagnostic, it started. I renamed S742diagnostic back and rebooted machine. Everything came up fine. ? I did not change anything. Never know?

One other thing, IF you can direct someone with console access...

The / key will abort a startup script. This will get you past the error next time.

Hi All, I'm facing this problem of extremely long bootup time for my server. It wasn't like this previously, i'm using a K580 running HPUX 11.11.

Currently it took 1hr 30mins to bootup. I've logged a case to investigate the problem but i would like to put it on forum to discuss with the experts.

Previously it took only 20mins, now i tried using single user mode and bootup to 3rd level, it took only 15mins.

I have simply no idea what is wrong with the normal bootup, could anyone kindly tell me how to look for the source of this long bootup problem?

I figured it that there might be some hardware monitoring process that needs a long time to process during the bootup before HPUX.

Anyone has any advise, please give me some tips, thanks!

Sincerely,
Edmund

Stop to start /sbin/rc2.d/S742diagnostic service on bootup. Start it manually after coming to terminal.

Change,

DIAGNOSTICS=0

on /etc/rc.config.d/diagnostic file.

It will not start that script. Are you getting any errors on syslog or console when starting up this.
