Assuming that you are referring to the kdump based dump-on-panic mechanism on i386 Linux, this is not available on s390. > It seems that if I don't want to have a dump disk on every LIN-z system > then I need to do the VMDUMP.

To answer your question: yes, a pool of dump disks would work, even across distributions.
