When using versioning in your media policies, if you delete a library, the tape containing that library will not expire. Use the Media Policy field 'Deleted library retention' to specify that the tapes containing these deleted libraries should be automatically expired. This Media Policy setting specifies the number of days that BRMS should retain the saved item information for those libraries after it has detected (via the Start Maintenance for BRM (
STRMNTBRM) command) that they have been deleted. Once this time period has been exceeded, the saved item information for those libraries will automatically be expired.
