SAM causes system crash

[Andrew Luis Arruza]

When I go into SAM on one of our servers, an A500, running HPUX-11.00, it causes the server to crash.
Any ideas will certainly be appreciated and as always, points gratefully given.
Thanks,
Andy

What's the error you're getting ? Any core file left behind ? Also take a look at /var/sam/log/samlog and post any errors here. That would help narrow down the root cause. What was the last thing you did prior to your SAM having the problem ? Patch install, kernel tweaks ??

Also check /var/adm/syslog/syslog.log for any errors.

Attached is the samlog.
Prior to going into SAM, I was not doing anything on this system.

Andy,

Are you saying that it cause your machine to stop running, requiring a reboot?

can you post your syslog.log file?


Did you modify the kernel, move the machine, or anything else, in anyway, before experiencing this problem?

Normal logs will be of no value in determining the reason for the crash...these logs don't exist, indeed, no files exist when the system crashes. In irder to determine the reason, you'll have to setup for a crash dump. This involves setting aside enough space in /var/adm/crash to hold about 1/3 to 1/2 of RAM (RAM=2Gb, then you'll need 700-1000 megs of free space). Edit /etc/rc.config.conf/savecrash to set:

SAVECRASH=1

Make sure there isn't any # in front of that line. Now you're set to crash the system again. When it reboots, there will be some large files in /var/adm/crash. Contact the HP Response Center to have them analyze the crash and they can recommend a fix.

On the other hand, from the sam log, it looks like the last thing that happened was a call to lookup things inside the kernel files, and in general, a system crash is either a patchable event or it is a hardware failure (ie, HPMC) which will require hardware replacement. Is your system up to date on patches? You should see the 2002 patch bundles on your system with:

swlist -l bundle

Without these patches, you'll have hundreds of problems, either now or later.

I have made no changes to the kernel or added any patches.

Here's the syslog.

The syslog shows SCSI error messages which are HW related. You should report these to your HW Support. SAM runs a number of commands when it loads including ioscan. So it's just a coincidence that the system crashes when you load SAM.

I guess this would bother me:

You need to clean up your filesystems.
