check the /var/adm/syslog/syslog.log

for errors.
If you had rebooted the system then check the OLDsyslog.log file.

ALso check the directory /var/adm/crash for crash files

You could check

/var/adm/syslog/OLDsyslog.log

/etc/shutdownlog

/var/tombstones/ts99 (This will list chassis codes if there is a hardware problem, which an HP engineer could use to find out what was at fault).

Hi,

please check following:

on chrashed Node:
1.)
# cd /var/adm/crash/crash.x
# more INDEX
---> check reason for panic

# . /usr/contrib/Q4/bin/set_env
# q4pxdb
# q4 vmunix
---> and debug the dump, if you have a contract with HP call them for help.

2.)
# more /var/adm/syslog/OLDsyslog.log
---> check here for a reason, such like "cmcld died", ...

on the other Nodes:
# more /var/adm/syslog/syslog.log
---> check here also for a reason

Regards,
Armin

Hi

/var/adm/syslog/OLDsyslog.log and
/var/adm/crash will give you the cause in detail

please check if patch:

10.20 PHCO_21061
11.00 PHCO_21062
11.11 PHCO_25723

is installed. If you can do following:

# . /usr/contrib/Q4/bin/set_env
# q4pxdb
# q4 vmunix

q4> run WH>wh.out
q4> quit

# more wh.out
---> here you will find al lot of informations, search for reason of panic

IF MC/SG toc'ed the system then you have to search in OLDsyslog for more details.

my guess is that the reason for the shutdown is a TOC, ie SG initiated.
Your syslog of all nodes should give you more.

See SG docs:
