Lizette, EFMT2 does not mean the tape is encrypted. In fact, it means it isn't. EFMT simply means Enterprise Format. EEFMT2 is the encrypted version. EEFMT means Enterprise Encrypted Format.
EFMT1 was the tape format of the original 3592 tape drives (the J1A models), EFMT2 is the TS1120 tape drives, and EFMT3 is the TS1130 drive native format which is related to the density and capacity of the tapes.

I have not confirmed or verified my colleagues' statement. If the DFHSM tape is actually EFMT2 then I will believe that it is being encrypted but not by DFHSM. The thought was there might be a DFHSM parm that did this rather than the hardware.
