Using TS1130 tape drives does not require changes to your installation's DFSMSdss jobs. When at least one of the output devices is encrypting data and you request software encryption, DFSMSdss overrides software encryption request for the output devices that encrypt data, and does not write to the output devices that do not encrypt data. To indicate that the tape device is encrypting data, DFSMSdss sets to one the following bits in the ADREID0 mapping: the EI26TWHE bit for the Volume Output Notification Exit (EXIT26), and the EI06THWE bit for the Write Physical Tape Exit (EXIT06). If you do not request software encryption, DFSMSdss can write to multiple output devices some of which are encrypting data in the hardware and some are not. DFSMSdss continues to inform your application whether a tape device is encrypting data and if all of the data is processed.
