z/VM guest example

With kdump, you do not need a dump device to initiate the dump.

Before you begin

Your Linux® instance must have been set up for kdump as described in Setting up kdump.

Issue the system restart z/VM® CP command, for example from a 3270 terminal emulation for the Linux instance to be dumped, issue:

#cp system restart

Boot messages for the kdump kernel indicate that the dump process has started.

kdump automatically collects the dump and reboots Linux.
