Testing the Configuration

The commands below will cause the kernel to crash. Use caution when following these steps, and by no means use them on a production machine.

To test the configuration, reboot the system with kdump enabled, and make sure that the service is running:

~]# service kdump status
Kdump is operational

Then type the following commands at a shell prompt:

~]# echo 1 > /proc/sys/kernel/sysrq
~]# echo c > /proc/sysrq-trigger

This will force the Linux kernel to crash, and the YYYY-MM-DD-HH:MM/vmcore file will be copied to the location you have selected in the configuration (that is, to /var/crash/ by default).
