Hi, I'd have to agree. Management of dataset and volume backups and dumps is tricky without HSM taking care of it by writing to tape, either real or virtual, quickly becoming a management overhead - though it did say "almost all".

The one logical capability of a tape data set, even one using virtual tape, that is not normally associated with a DASD data set is the innate ability to continue to exist for hours, days, or even longer after a new data set with identical name has been created, depending on how tapes volumes are scratched. The use of tape could mean the application is depending on that retention as an implicit and essential part of recovery should programming errors or other disasters occur during application processing, especially if the problem is a subtle one that isn't caught immediately. Throwing out that capability without providing a suitable substitute is something you may live to regret. Joel C. Ewing -- Joel C.
