I don't see why that would not work. Have'nt tried though. In case you're
running
on z/VM, consider using DCSS with xip2 filesystem instead of shared dasd.
Major
advantages are improved performance and reduced memory consumption, major
disadvantage is that your shared filesystem may not be larger than 1.9 gig
or so.

>and does it work if the shared OS dasd is an LVM?
LVM works pretty much different from old 2.4.x. days now. It is now based
on a common infrastructure called
"device mapper". All userspace tools (pvcreate, lvcreate ... and such)
work same as before.
