What means crush dump

[rustam_2]

Hi all,
This morning my DB server wast enable to connect. I connected to my DB server where runs HP-UX 11v3 and saw some process which were running (making dump file).
After this OS went to restart but started longer than normal startup. I checked SL->Event->warning and there where these informations:

I dont know why there was Panic shutdown and what it means. I guess no power failure was here, coz other servers didn't went restart.

i checked /var/adm/syslog/syslog.log and there are few information about after restart system. Where can i find whole log, what happened and happens?
Coz now DB works very strange, slow and sometimes lost connection. First i want determined what were\are happened\happening with OS. Then will check DB' log. For now DB's log is ok.

thanks for any suggestions and helps.

Regards,
Rustam

Hi Rustam:

The init proccess savecrash saves the crash dump information of the system (assuming one
was made when the system crashed) and writes a reboot message in the shutdown log file.

man crashutil,savecrash, crashconf,

Verify thge content of default SAVECRASH_DIR=/var/adm/crash

# cd $SAVECRASH_DIR/
# ll -d crash.*

# cd cras.x

# more INDEX

# more /etc/shutdownlog

From HPUX 11.31 crashinfo is supplied by default and you can find it in /opt/sfm/tools/

crashinfo is an HP-UX crashdump analysis tool. It is supplied for use by, or under the direction of Hewlett-Packard support personnel only.
