This question has overtones (undertones?) reminiscent of avoiding PDSE. Just isn't necessary. Our HFS/ZFS files have been SMS managed for many years with no problems. I'm pretty sure that no particular task is required to open an existing file. If DFSMS is broken in some catastrophic way, you have a lot of other problems to occupy your attention.
SMS can help a lot for allocating new ZFS to a specific DASD pool and keeping out interlopers who shouldn't be there. Not to mention the advantages of EAV. . .

If applicable, IPL onto the new ones, before deleting the old ones. I use DFDSS to clone filesystems as a regular part of maintenance. If they are mounted READ only, then the DFDSS job can be run anywhere. If mounted RDWR, you need to either unmount, or expect DFDSS to temporarily quiesce the filesystem from updates while running. _________________________________________________________________ Dave Jousma Manager Mainframe Engineering, Assistant Vice President [email protected] 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:[email protected]] On Behalf Of Shaffer, Terri Sent: Tuesday, September 19, 2017 2:11 PM To: [email protected] Subject: Extended format system ZFS files **CAUTION EXTERNAL EMAIL** **DO NOT open attachments or click on links from unknown senders or unexpected emails** So I have a question. Is it possible to convert my z/OS system ZFS files from SMS Extended to Non-SMS datasets? What would be the process? Repro out and back? Is there a simpler way? I know technically this works fine, but I don’t like my system datasets being SMS managed and the previous person here set this up.
