Lots of places you can check:

/etc/shutdownlog

/var/adm/syslog/syslog.log

/var/adm/crash

/var/tombstones/ts99

There are a couple of files that you can look at, but for most of them chances are, you'll need the help of Hewlett-packard to interpret them.

the first I like to look at is /etc/shutdownlog. The last line should tell you whether the server panicked or shutdown with a few codes beside them.

Another one, obvious one, /var/adm/syslog/syslog.log and OLDsyslog.log

You can also look at /var/tombstones/ and see when ts99 was created. That coudl show a hardware problem.

There is also /var/adm/crash that, if enabled properly, should dump your system into a directory called crash.# (# being a number). this dump can be analyzed by HP and give you a pretty good indication why your system may have crashed.

Hope this helps.

You could check these:
1) /var/adm/syslog/syslog.log, /var/adm/syslog/OLDsyslog.log
2) /etc/shutdownlog
3) root mail
4) HPMC errors and time stamps from boot menu
5) /var/adm/crash files and do an analysis on that
6) /var/tombstones files

Hi,

The most important log in my opinion:

/var/adm/syslog/syslog.log

Alfredo --

First do a: tail /etc/shutdownlog.

There is a good chance that it will say something like:

panic:

Please post that message here and I can tell you where you may need to look.

There is an ITRC document that can help you if your system crashes and you have a dump saved in /var/adm/crash/.

The document tells you some basic utilities to run to check on the type of failure.

As others have stated though, a definitive answer usually will require you to open a call for HP assistance due to the complexity of troubleshooting dumps.

The document which tells you how to Pre-Process Dumps for HP is OZBEKBRC00000611.

Best regards,

syslog is pretty clear
as well as the shutdown log

your tombstone log wil tell if a processor or memory problem caused the proble

but its dificult to read
i know the chasis codes shwo the status of the processors and i believe if the code ends in fb or something like that that processor has a problem

sometime trying to get info on how to read these from HP is like pulling teeth tho heh
