>I have a question about OMVS HFS files. I have the compatibility maintenenance installed on my z/OS 1.7 system, in preparation for installing z/OS 1.9.

As an example, I copied OMVS.ROOT to OMVS.SERVICE.ROOT, and applied all of the maintenance. >My question is, can I use IEHPROGM to rename the Service file back to OMVS.ROOT? When I clip the pack to IPL, the catalog will point to the correct dataset name. The current IPL volume is Z17RES, and my maintenance volume is ZA7RES, so I will clip ZA7RES to Z17RES, and IPL it in my test sysplex. >If I can't do that, how should I do it? That is not the way I do it, but it should work. Or rename with any other method (ISPF etc.). As long as it is indirectly cataloged, it should be fine. I've never done cloning that involved clipping volume names. I've flipped between an A/B set (in small shops, very little spare DASD) where I copy the "live" volumes like you did, apply maintenance, then IPL from the new set. But everything except the HFS files were indirectly cataloged so no CLIPs were needed. The HFS files had the (primary) sysres as part of the name to facilitate mounting the maintenance root. The other way (most common now) is to always apply to a maintenance set of sysres volumes and clone those to the IPL-able set. BTW, if you want to see samples of cloning jobs, see the JOBs/Doc section of my web site. CLONERSO is the "A/B" set method and CLONERES is similar to what I do today with cloning a maintenance set. The examples use FDR so that is good for you. One difference from the sample on my web site is that I converted all our HFS to zFS after we migrated to z/OS 1.8. You can't indirectly catalog a zFS. I also had to add a ZFSADM step to quiesce the zFS files prior to the FDRCOPY since "HFS=QUIESCE" is not supported for the COPY TYPE=DSF (I hope innovation fixes this eventually). Of course the is an unquiesce step also after the copy. DFSMSdss does the quiesce automatically for both HFS and zFS.
