Thanks for the suggestions so far and the confirmation that the TMC's don't need any change. I think I know most of the traditional device migration approaches and techniques. I work with a tape hardware vendor and have been involved in tape management software for lots of years. I did not describe any specific hardware configurations because I am looking for something that can be adapted to many different migrations and different situations. I am dealing with virtual tape devices/appliances which can offer some unique challenges with different connectivity configurations. Migration solutions that do not require the recreation of data sets are much easier to do. That's why I am looking for ways to modify the actual hex device codes in the catalog.
Specifically, I am looking for suggestions on what is available for mass catalog updates. I'd rather not reinvent the wheel if there are useable tools around.

Our standard allocation is TAPE, defined in the IODF eligible device table. A few years ago, when we moved from physical tape to virtual tape, I added the new virtual tape to TAPE. The old tape was Quiesced (SMS). Most of our tape is short term retention, so having all the new go the virtual and read the physical tapes from the old worked welln We used CopyCat (we use CA1) to move the longer retention tapes. Using the esoterics also meant that we didn't have any JCL changes. If you change the device type in the catalog and the tapes are not migrated to the new device, you may well have trouble mounting the old tape. If you can close the catalog and export it you could run idcams, iebupdte or rexx or another program to make the catalog changes and rebuild the catalog. It was our experience that adding the new virtual tape to the TAPE esoteric in the edt, and letting SMS take care of most of the rest. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
