... more on this... If I do a "runlevel" command on linux I get "unknown" as the response.
If I set the runlevel to 3 via "init 3", then "SIGNAL SHUTDOWN guestname" works properly. Looking on the Linux-390 listserver, I see some similar problems there wi th systems without a run-level set, albeit for SLES8. ... I will pursue this on the Linux-390 Listserver. Thanks all for your help so far. Fred Schmidt
