Brian,
What Tom is talking about is SERVICE one z/VM system then clone only the
parts that are needed. (I use DDR with the reorder option - simple)
example here is:
ZVTRES, ZVTSP1, ZVTPG1, ZVTS01, ZVTS02, ZVTS03 as provided at INSTALL
time and Serviced when needed.
our LINUX images have ZLARES, ZLAPG1, ZLSP1 and ZLBRES, ZLBPG1, ZLBSP1
with the needed mdisks from ZVTRES, ZVTS01, ZVTS02, ZVTS03 for CP and
CMS to ipl all fit on ZLARES or ZLBRES.
6 packs for test and Service and 3 packs for production.
fell free to keep in touch

Tom,
Yes, I have forwarded Malcoms' info and links to management to look
at. We are still way to new to VM to consider what I know as qualified
but alas, I am the systems programmer for better or worse. SO, I must
ask, are you stating below that I can share a RES vol with multiple VM
LPARs? I have no idea what you mean by the CP areas being what I need
multiple copies of. I have to ass/u/me you are referring to some minidisks.
I currently maintain two VM systems, one on each frame. They are kept
completely separate since one is prod and one is test. I learned from an
IBM'er how to rename vols and change parms to have a 520res, 520spl, and
520pag along with a VM7RES, VM7SPL, and VM7PAG. I figured I'd have to
create another set of these. So, if I understood you correctly, would
you please point me to some RTFM material that I could peruse and
hopefully put to use.

The vast majority of RES and WK1 packs are used to build and maintain
VM. You only need 1 copy of that. The CP areas is the only areas
that you need a copy per copy of VM running. (you might want to add a
copy of MAINT's 191 to that, but it really isn't necessary).
Now, is it worth it? Not really. DASD is really cheap nowadays. But
if you don't have the dasd available, then the next pack is rather
expensive <G>.
However, based on what Malcolm sent about subcapacity licensing for
zLinux, that looks like the way to go and it will solve your concerns
about multiple VM systems.
