DFSMS hierarchical storage manager (DFSMShsm), a z/OS functional component, automatically manages low activity and inactive data in both system-managed and non-system-managed environments. DFSMShsm also provides automatic backup and recovery of active data in the same environments.

This topic describes specific changes to DFSMShsm support for the new 3592 Model E05 tape drives. DFSMShsm can use 3592 Model E05 for all functions. The 3592 Model E05 uses existing cartridge media (MEDIA5, MEDIA6, MEDIA7 and MEDIA8) and also supports two new media types: MEDIA9 (700 GB R/W) and MEDIA10 (700 GB WORM). MEDIA9 is available for all DFSMShsm functions, while MEDIA10 is intended specifically for ABARS processing of ABACKUP tapes.

DFSMShsm also adds support for enterprise format 2 (EFMT2), a new recording format that is required for using the new MEDIA9 and MEDIA10 cartridge media.
