Automatic dumping

You can configure a dump device that is automatically used when a kernel panic occurs.

If you set up kdump, a kernel panic or PSW restart automatically triggers a dump.

For Linux® on KVM, you can also use the on_crash element in the virtual server configuration to set up automatic dumping.

For Linux in LPAR mode and Linux on z/VM®, you can also use dumpconf to set up automatic dumping for stand-alone tools, or for your backup dump solution. See dumpconf - Configure panic or PSW restart action.

Once you have set up the automation, you can cause a kernel panic to test the configuration.
