Re: How to isolate cause of system crash
If the system is part of a serviceguard cluster, switch work could trigger a TOC, transfer of control and crash by interrupting the heartbeat.
To get good help, you are going to need to provide a lot more detail on your environment.

Re: How to isolate cause of system crash
However, the cluster was down after the reboot so there is a chance MCSG may have had a hand in it. I restarted the cluster, the response was cluster not started, but the cluster did restart w/o incident. Strangely enough, there were no MCSG-related messages referencing cluster activity in syslog.

Re: How to isolate cause of system crash
- Check GSP chasis logs.
- Check /var/adm/crash/crash.x # where x is crash number.
- check /var/tombstones/ for any file with grep cpu # if true cpu caused the crash.
- check /etc/shutdownlog
- If it is due to the power trip, there will not be any log in the server. But GSP log will have power failure log.
- Check the timestamp of last portion of /var/adm/syslog/OLDsyslog.log and first portion of /var/adm/syslog/syslog.log and you can figure out what time it was rebooted and if it is related to the maintenance.
Cheers,
Raj.

Re: How to isolate cause of system crash
The MP in IA 64 or GSP in PA-RISC would almost certainly have some related entry...
That would be a start to get to the root cause...
Let us know your progress, findings.
