32.2.4. Testing the Configuration

To test the configuration, reboot the system with kdump enabled, and make sure that the service is running (see Section 12.3, “Running Services” for more information on how to run a service in Red Hat Enterprise Linux):

service kdump status

~]# 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

echo 1 > /proc/sys/kernel/sysrq
echo c > /proc/sysrq-trigger

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