A non-system-managed tape library is all the volumes, shelves, and drives not in an automated tape library or manual tape library. You might know this as the traditional tape library in a data center or as an automated environment that is not system-managed. DFSMSrmm provides complete tape management functions for the volumes and shelves in this traditional tape library.

All tape media and drives supported by z/OS are supported in this environment. Use DFSMSrmm to fully manage all types of tapes in a non-system-managed tape library, including 3420 reels, 3480, 3490, and 3590 cartridge system tapes.

You can also use DFSMSrmm to manage volumes in any automated tape library that has special software including an IBM® Tape Library Data server that is managed using Basic Tape Library Support (BTLS).
