Using encryption-capable TS1120 tape drives does not require changes to your installation's DFSMSdss jobs. It does, however, require changes to your installation's data classes and DFSMShsm dump classes, as described previously in this information. These considerations are briefly summarized here for the awareness of DFSMSdss administrators.

System volumes such as SYSRES should not be dumped to an encrypted tape data set. Because the DFSMSdss Stand Alone Restore program does not support restoring data from encrypted tape volumes, any encrypted system volume will not be able to be restored using the DFSMSdss Stand Alone Restore program.
