Perhaps IBM's new "IBM Tape Manager" product >uses that field? IBM Tape Manager for z/VM does not use this field. On behalf of each VM user, we act like any other requester to RMM. There is no special VM marking of our tapes in the RMM catalog and there's no special flag in ou r requests to indicate they are coming from VM. Instead, we rely on the customer's security mechanism (e.g. RACF or other ESM on z/OS) to determine if the requesting VM user is authorized to the tape. With Tape Manager, a z/OS user and a z/VM user could technically be authorized to access the same tape. Tracy Dean IBM Product Manager
