Panic in C200 workstation

[P.PARTHIBAN]

Hello all

I am facing a problem in C200 workstation.
some times the system starts core dump.
I have seen the INDEX file which is in
/var/adm/crash/core.2 directory . It
says panic is due to data page fault.
I am not able to find out tombstones
directory which contains PIM information
Can any one tell me how to resolve this.
OS ver is HPUX 10.20

Thanks and Regards

Normally data page faults are patch related. Load up the latest patch bundle for 10.20 - June2000 is the latest and you can download from the ITRC. If this doesnt stop your crashes run XSTM (from Onlinediag from the Support Plus CD) and go to TOOLS->UTILITY->RUN->LOGTOOL and from the new window go to MEMORY->REPORT LOG->VIEW DETAIL and see if you have any memory errors reported. If so get the memory replaced.

Check the error messages in /var/adm/syslog/OLDsyslog.log and also do mailx to see mails to root. tombstones file is in /var/tombstones. Check out patch PHSS_14980.

Check if you can't find pdcinfo on your box and the online diagnostics is installed then install PHSS_14980. This patch needs the diag2 driver on the system which is only installed with the diagnostics.

In general, a Data Page Fault panic is not caused by Hardware, although there are exceptions to the rule.
Normally a patch will fix whatever symptom has caused the problem, but you may have experienced some failure that may not be covered by a patch.
My suggestion would be to get the dump analysed by your local Response Centre to verify the panic, or at least load the latest patch bundle.

Hi,

when your system is down, you can stop the boot process and read the PIM Info directly.
First you have to check for a valid time stamp. If it's not a valid time stamp then ignore it and send only the core dump files to HP office for analyze it and find patches for your system.

When your system is UP, run xstm, check the CPU Info, read in the CPU HPMC section information, if any valid time stamp and read/or save it (you can use cut and paste?).

If it's an HPMC case, your C200 hase an hardwere problem. Then call HP office for more help.

If you need to re-genarate the dump file, do this:
#mkdir /tmp/bigspace

#savecore -r /tmp/bigspace

#cd /tmp/bigspace

#tar cvf /dev/rmt/0m .

Send the DDS Tape to HP office for analyzing.

In case of Disk space problems do this:
#savecore -r -t /dev/rmt/0m

Send the DDS Tape to HP office for analizing.

Good luck

q4. It is an prorgam that allowed you to pre-analyse the crash file and identify if you have HPCM codes (hardware failure).
Log a call with HP and you'll get instruction how to run it.
Before that if you wish, you can play with adb. (se man adb).
Good luck.
