Re: server reboot

Hi,

Have a look at the /etc/shutdownlog or check for entries around the time of the reboot in the /var/adm/syslog/OLDsyslog.log

Regards.

Re: server reboot

hi,

check syslog.log shutdown.log and the event logs in MP/GSP.

Re: server reboot

tail /etc/shutdownlog

if the server went down gracefully or due to a recorded panic, it will show up there

if it was a crash, check the contents of /var/tombstones/ts99 for clues

last but not the least check the bottom portion of /var/adm/syslog/OLDsyslog.log

hope this helps

Re: server reboot

Hi,

There are many reasons for the server to go for a reboot.

If it is user initiated, check in /etc/shutdownlog and /var/adm/syslog/syslog.log

If it is software panic reboot, check /var/adm/crash directory. There will be crash.x directory with dump files. We need to analyse the dump files to find out the software issues.

If the panic is due to hardware failure, check the file /var/tombstones/ts99. If this file is created with server reboot time, you can analyse it. It is a text file only.

If the server rebooted abrubtly due to power outage, then you won't find any clue on the OS side.

To analyse crash dump and ts99 file, you may need HP help.
Best wishes,

Ganesh.
