Which tape management system? With CA-1, a tape is returned to the scratch pool when every dataset on the tape expires. If the tape is SMS managed, then the CA-1 system communicates to OAM to expire the tape to SMS. OAM then communicates to our VTS/ATL to set that volume to SCRATCH status in the tape library.
When CA-1 expires a dataset on a tape, part of the process, at least as we have it set up, is to uncatalog the dataset name - assuming the dataset is catalogued on the given tape volume. I don't know how DFSMSrmm does its expiration processing. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
