Therefore customers will issue "system restart" for creating a dump. If kdump is not enabled, currently "PSW restart" will reboot the system and then no dump can be created any more. In order to still allow a manual stand-alone dump in the case a user issues "PSW restart" on a system that has not enabled kdump we now stop the system.
