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).

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 r. -----Original Message----- From: RPN01 [mailto:[EMAIL PROTECTED] Sent: Friday, July 18, 2008 10:09 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: z/Linux cloning 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. -- Robert P. Nix Mayo Foundation .~.
