We have noticed this behavior on our 1.12 systems too. My cloning process copies the base file systems that match the maintenance zones, that we NEVER IPL from directly. As long as the /Service file systems are unmounted cleanly before my cloning process everything works fine.
We noticed this behavior when we IPL our D/R system from replicated disk, where there was no quiesing of file systems beforehand. _________________________________________________________________ Dave Jousma Assistant Vice President, Mainframe Services david.jou...@53.com 1830 East Paris, Grand Rapids, MI 49546 MD RSCB2H p 616.653.8429 f 616.653.2717 -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@listserv.ua.edu] On Behalf Of August Carideo Sent: Monday, June 18, 2012 1:36 PM To: IBM-MAIN@listserv.ua.edu Subject: Re: z/OS 1.13 - USS Upgrade Problem This is interesting. Normally, when we copy a sysres, we mount all the new file systems on an alternate mount point, so we can run compares and insure the new copies are good. That way, the IPL is not the first time a new file system is mounted. We tried an experiment: set up a job just to mount and unmount all the new file systems we set up for the D1 1.13 system; most had not been mounted since they were created. The first time tried it, it took nearly 34 minutes to mount and unmount something like 35 file systems. ran it a second time, and it took 4 minutes. Maybe you could suggest such a job to 'break in" newly copied file systems prior to their first IPL. This e-mail transmission contains information that is confidential and may be privileged.
