I would be interested in either of these approaches. I did reply to
Robert Nix offlist, but haven't heard back...so assume that he is not
"in the office" currently. We are relatively new users to zVM and Linux
(RHEL).

Thanks,

Kevin

Our cloning process sounds similar to yours. I have an EXEC which takes
care of poking VM:Secure correctly, FLASHCOPYing the necessary MDISKs,
and then updating our internal recordkeeping.

One command, about two seconds, then another thirty or so to IPL
(assuming DNS is updated ahead of time). It's fairly well customized to
our site requirements, but the basic building blocks could be  easily
adapted to other sites. I also suspect now that SLES10 SP2 includes
support for the VMUR driver, even though I haven't yet looked closely at
the options, we'll be able to get even more fancy with our automation.

I can also share details with any interested parties.

Some of the drawbacks of doing it from Linux (instead of from CMS) are
that FLASHCOPY needs privilege class B, and you're more likely to
aggravate LVM.

ok

We have a cloning process that is down to a single zVM command to create
a new image, and we can create new images in about 8 minutes time from
zVM command to being able to log into the new image. The master images
occupy disk space, but are not running at any time. Since the disk
copies are done from zVM via Flashcopy, the cloning process is
independent of filesystem choice and works with LVM managed disks. As
far as I know, we're the only ones using the process at the moment. If
there's an interest, I can share it with you.
