Bill,
THANX for the info!!! My problem is that I really don't
understand the parts of the system to clone. ie - just which
minidisks do what. AND in the time frame it looks like I'm being
given, I doubt I could come to that understanding. By the way, you
said you were running HATs on I think on a z9BC with two images to
support it. How many concurrent sessions does that support? This
thing was tested by someone here on wintel, they said buy to it
management, and now they've all come to the agreement to run it on
VM/MFL. So we haven't even tested it yet in this world. NUTS comes to
mind... As I said in another email, I'm gone now for about two weeks.
Depends on weather the wily buck... I'll check back to see what you
had to say...

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.
