In a stand-alone environment, the SETOAM TAPEUNITNAME parameter in the CBROAMxx member of PARMLIB can be specified using an esoteric that contains encryption-capable TS1120 (3592-2E) tape drives. In the stand-alone environment, 3592 Model J, 3592 Model E05 (not encryption capable), and 3592 Model E05 (encryption capable) drives need to be segregated in their own unique esoteric in order to prevent allocating a 3592-J or 3592-2 drive for a volume written with EEFMT2 recording technology, because EEFMT2 is only compatible with 3592-2E drives. You can use the SETOAM DATACLASS parameter to specify EEFMT2 recording format to encrypt data, or specify non-encryption formats (EFMT1 or EFMT2). If no recording technology is specified, the default recording format for the TS1120 drives is EFMT2 when writing from load point. In an IBM tape library environment, the SETOAM DATACLASS parameter at the storage group (or global level) can be used to specify a desired recording technology and ensure allocating an appropriate drive.

The ERDS Physical ID (EPI) value for the 3592-2E drive is a hex '13' and is stored in the DB2 TAPEVOL table of the OAM Optical Configuration Database (OCDB) for a volume written in EFMT1, EFMT2, or EEFMT2 by a 3592-2E drive, and displayed, as appropriate, in the volume display. For the encryption-capable TS1120 tape drive (always in 3590 emulation mode), OAM derives the media type and capacity from the control unit. If EEFMT2 recording technology is used to write on the volume, the MEDIA5 and MEDIA6 capacity is 488281088 KB. The MEDIA7 and MEDIA8 economy capacity is 97655808 KB. The MEDIA9 and MEDIA10 extended capacity is 700 GB.
