Re: DASD Subsystem Migration
Billy, Usually EMC copies the data from the old box the the new box, using an EMC-utility, no mainframe IO involved. Shutdown mainframe, connect to the new box, and IPL. Bye, Geert.

Re: DASD Subsystem Migration
We used a standalone facility provided by our hardware vendor (EMC in this case). System(s) came down, EMC ran their utility which was very quick, and we IPLed the newly copied res pack(s) on their new addresses. We used no mainframe facilities other than our standard backups in case of complete disaster.

Re: DASD Subsystem Migration
We did a migration just a few months back. We only run Linux under z/VM, all of our z/OS images run in their own lpars. We used some z/OS software (TDMF) to move the z/VM volumes. It did require us to bring down the z/VM lpars during the move.

Re: DASD Subsystem Migration
As far as I remember over the last few times we changed DASD, we hooked up the new storage to the old with PPRC and then started up with the "mirrors" as our primary disks. I don't think we have bothered to actually *copy* disks in a long time.

Thanks, Billy I actually know of one z/OS installation that used a utility like FDR to move their z/VM volumes. It was much faster than DDR and we only had a problem with one volume (due to a volume label issue). -- Rich Smrcina Velocity Software, Inc. http://www.velocitysoftware.com Catch the WAVV! http://www.wavv.org WAVV 2011 - April 15-19, 2011 Colorado Springs, CO
Re: DASD Subsystem Migration
Hi Billy, I'm doing it right now... we are using PPRC... we are migrating from ds8300 to ds8700... We had no problem, but pprc only allowed copy to same types of volumes... ex: ckd to ckd or fb to fb... not allowed mirror ckd to fb volumes... make the copy using ds to quick and t On Tue, Jan 25, 2011 at 10:08 AM, Billy Bingham < billy.bingham...@suddenlink.net> wrote: > This email was originally about FDRPAS, but I have changed the subject to > reflect a more broader subject. > > What do other shops use when they have to migrate their VM system to a > new DASD subsystem.
