Idham — Wed, 17 Dec 2008 03:08:34 GMT

Actualy I just ignore this message earlier on (below dmesg).
But yesterday 15 Dec 08...the server rebooted by itself. Maybe due to this error..so,how to overcome/troubleshoot this situation?...

fyi..already ioscan on FC and DISK. No problem detected.

>the server crashed. Maybe due to this error? so, how to overcome/troubleshoot this situation?

First look at the crash/logs from yesterday.
Do you have a crash dump in /var/adm/crash?
Look at /var/adm/syslog/OLDsyslog.log to see if there are any I/O errors logged from Nov or yesterday.

Hi Idham,

dmesg errors may be old one but,

Run the CSTM utility
# cstm>selall>infolog ; wait

check for the errors.
check for the old syslog for any errors.
check for the diaglogd daemon is active.

Thanks,
Analyst.

These error are of 26Nov and if this is the llast few lines of dmesg then it is not at all the cause of server crash.
Above error says and logging facility is receiing lot of alert/errors which can be of anything in server.

check /var/adm/messages entries for 15th Dec!!

Do u have any other error in syslog.log, any crash dumps ts99 file??

Re: dmesg got error

Idham — Wed, 17 Dec 2008 03:57:27 GMT

I've checked ..but there was no error in syslog/OLDsyslog and /var/adm/crash/

What is "crash dumps ts99 file" anyway?

Re: dmesg got error

Kapil Jha — Wed, 17 Dec 2008 04:03:42 GMT

Just check /var/adm/crash directory if you have anything.
ts99 file is in /var/tombstones directory

These are the files which are used to investigate the cause of crash.Crash files are actully memory image when system booted.

as there is no error after 26Nov you will have to have crash file else it would be tuff to find out the exact cause of crash.

1.Cstm is a support manager tool , use the sam way how I wrote.
#cstm
#cstm>selall
#cstm>infolog ; wait

displays the hardware information completely

2. #ps -ef |grep diaglogd

>:will it affect running oracle db.--->you are not stopping anything, its only checking.

Thanks,
Analyst.

Hi,

As per your log I can see date was old (Nov 26 22:07:56) what you get at your /var/adm/syslog/syslog did you find any error message over there.

Idham,

#cstm>selall>runutil> choose logtool-->SAV-->save the file and find the errors.

Seems to be some memory h/w issue.

Else upload the same.we will analyse it.

Thanks,
Analyst.

To check if diaglogd is running:

# ps -ef | grep diag

you should see something like this:
root 1467 1240 0 Dec 12 ? 0:19 diaglogd

To check the Raw Summary (rs) of I/O errors in logtool:

# cstm
cstm> ru logtool
Logtool> rs
Logtool> q
Logtool> saveas
(give it a location and name you'll remember)
Logtool> done

To format the current raw file to get detailed I/O error information:

Logtool> fl
(select default location)
Logtool> q
Logtool> saveas
(choose a name and location you'll remember)
Logtool> done
Logtool> exit
cstm> exit

view the files you created to see where your errors are or post the files here.

HTH,
