I would like to test whether my server creating a crash dump upon a OS crash. I can see the /etc/sysconfig/kdump
config file is configured.
So I issued the command to kernel panic echo c > /proc/sysrq-trigger
so it crashed the server but it never create a dump file for some reason. This is HP BL460g7 blade with ASR disabled.
When I trigger the kernel panic it crashed but stays about 10 minutes (looks like its trying to save a crash dump) but it never. I checked the message logs but cannot see reason why its not dumping. Main problem is how do I find why it's not dumping a crash file, is there are any logs I can check what has really gone wrong?
I'm using SUSE Linux Enterprise Server 11 (x86_64) SP 1.

Did you follow the steps explained here?
SUSE Support - Configure kernel core dump capture
The most important tasks should be:
Then please reboot your system and run:
sync; echo c >/proc/sysrq-trigger
After another boot please check for new files in /var/crash
. If this doesn't work for you, please show us the content of /etc/sysconfig/kdump
and at least the output of
cat /proc/cmdline
chkconfig boot.kdump
Do you have a display connected to the machine?
