OS Panic Crash Help

Steven Chen_1 — Tue, 21 Sep 2004 16:49:00 GMT

Hi,

I have a K260 of 11i that crashed 3 times. First 2 times I did not have any dump file generated, this time I tried to get TC for the dump. But I waited for 1 hour the TC was still hang there. I have to hit enter to terminate it.

I would like to get help:

1) how to use TC, how long does it take (3G mem)?

2) on tiny screen it showed something when crash happened:
FLT B800
OS PANIC CPU012

Can somebody comment and help?

Appreciated!!

Steven

Do you have a valid dump volume configured in the system ?

1) Boot the system in multiuser mode
2) Execute lvlnboot -v command and make sure there is a pointer to the dump area
3) Execute /sbin/crashconf -v command

Even though you have 3 GB physical memory, only a portion of the memory will be copied to the dump area. crashconf command will tell you the size of the crash dump you can expect.

Edit the /etc/rc.config.d/savecrash file and set SAVECRASH=1 and SAVRCRASH_DIR=/var/adm/crash

Make sure you have enough free space left out in /var/adm/crash directory. Ideally you would have a seperate /var/adm/crash filesystem with a size equal-to or bigger than the dump size reported by the crashconf command.

Now press the TOC button. system should dump and reboot. Should not take more than 10-15 mins.

During the reboot, system crash dump is stored to /var/adm/crash by the /sbin/init.d/savecrash script.

The FLT B800 just indicates that HPUX detected a PANIC condition. You really should not have to do a TOC or TC to capture the dump. The dump should be generated for you.

After the machine boots, look in /var/adm/crash/, if anything recent is in there, these are your crash dump files.
