Using an encryption-capable TS1120 tape drive requires changes to your SMS data class definitions, as described in DFSMShsm considerations for the encryption-capable TS1120 tape drive.

For tapes that require software (or host-based) encryption, ensure that your dump-requesting jobs use only tape drives that are not enabled for hardware encryption. To do so, check the data classes of the output ddnames to ensure that the jobs do not specify a data class that requests encryption from the encryption-capable tape drives.
