We have 3000 tapes. They are 3490 tapes and we're phasing them out. We recently moved our datacentre and somehow these tapes were left behind, not only that but they were also degauzed. Now we have about 2500 of those tapes with HSM datasets on it. Our catalogue has all these datasets in MIGRAT2 status that can't be restored. There is about 50-60 datasets per tape. Is there an easy way of updating our catalogue rather than going through each tape and uncataloging or deleting one dataset at a time.
