If you want to use reserve/release on the disk you must have all systems link to
the same MDISK with MWV on the statement. That is the way you have it now. If
you change it to have a different MDISK statement for each guest then
reserve/release will not work. I don't know if z/OS uses reserve/release to
serialize access to dasd or if it uses something else.
You are doing it right now. If you make the change I can not guarantee that it
will fail. :)

I have a situation where multiple z/OS guests need to share DASD. In the
past I have used a userid as a disk holder with MDISKs using DEVNO and MWV.
The guests would then LINK to the MDISKs using MW. It has been suggested
that I eliminate the disk holder userid and use MDISK statements only. Each
guest would then have an MDISK for the same address. For example,
MDISK D000 3390 DEVNO D000 MWV
Does anyone know if there is any advantage or disadvantage to one way over
the other?
