HP 9000 Crash..?

Nagamani — Mon, 09 Apr 2001 04:22:12 GMT

Hi
We have HP 9000/879/K260 Server with HP-UX ver 11.0. Recently the server crashed and rebooted. The shutdownlog says : Reboot after Panic: Data Memory Protection Fault
What does this statement refer to &
What could be the cause of the failure..?

A DMPF is a system panic that could be either hardware or software. I suggest you get a call logged with your support people.
You may want to see if a tombstone has been generated with valid timestamps in the file unde /var/tombstones.

Check if you have something under /var/adm/crash. If so, you can analyse it with q4.

Hi
From the /var/tombstones/ts99 file, it appears the reboot was not due to hardware error. There are no errors logged. So this could be due to s/w error...?
vmunix is created in /var/adm/crash/crash.3 directory apart from image.1.1 & image.1.2 files due to this crash. These files can be deleted...?

No, you should not delete it!
If you don't know how to analyse them, then send it to HP!
They'll tell you what happened.

Hi,

Perform a STM diagnostics "exercise" (if possible) or "verify" and subsequently "information" on your physical memory.

This will tell you whether you are facing a hardware memory fault.

Hope this helps. Regards.

Hi
Do not at present delete your crash files as these can be analysed to fing out what caused the crash.

If you have HP support request that they look at the crash files.

Also the following can be used to examine the core files:-

cd /var/adm/crash/core.*
q4 .
trace event 0

HTH
