DFSMS software support for the encryption-capable TS1120 tape drive addresses media management and data allocation in an IBM 3494 Automated Tape Library, in an IBM 3584 Automated Tape Library, and in the manual tape library (MTL). You can manage media and allocate data to appropriate non-library (stand-alone) drives through segregation of the real and emulating drives, third-party tape management software, or user-written applications. You can use the encryption-capable TS1120 tape drive on systems that are running z/OS V1R4 and above. However, to use media types MEDIA9 and MEDIA10, z/OS V1R5 and above must be used.
