Russel, Lizette, One of the requirements I gave myself is to make it transparant to the user. I have stopped finding owners of datasets, arguing about their requirements, explain the technical need and go through all kinds of testing and acceptance procedures and decided to do everything under the hood transparently. E.g. I gather statistical information about use of dataset and calculated a group of dataset patterns of datasets that are (nearly) never referenced again after the day of creation. In my ACS routines I change the requested management class in order to Archive (CA-DISK term for Migrate) them after 2 days. Simple disk space saving without any user discussions.
Therefor I don't want to change anything in the specified dataset retention period, but I want to provide a safety net, that still provides a last resort if the dataset has been expired correctly according to all the requirements. The 'retain days only backup' is such a safety net, that is not a user requirement, but an extra backup-backup that we provide unsolicited. I am looking for something similar if the dataset is under CA-1 control i.s.o. SMS control. The R9 feature comes close, but indeed, it is only for catalog control tapes, and for all catalog control tapes and that is too broad. The same applies to the TS7700 HOLD option for the fast ready category. It could become possible if CA-1 controls tapes with a management class, according to the SMS rules and support a 'retain days expired tape' option.
