We have had a problem with various versions of z/VM 5.x (we are on 5.4 currently) where the DISABLE ALL DEVICES took an extremely long time on a 1st level system. When I say long, I mean looonnngggg (sometimes up to 45 minutes). We pinned the problem down to 2 boxes of 4096 non-IBM (SUN/STK) DASD that was giving different exception responses at this stage. There was disagreement because Sun/STK said they were doing it by the spec while IBM said differently. I would have to look up the details but we got a fix from IBM to exclude this range of DASD from exception processing during SHUTDOWN and we are now fine. Not sure if this is any help.
