JES3, a z/OS® MVS™ subsystem, manages resources and work flow before and after jobs are processed. You can enable JES3 to allocate 3592 Model E05 tape drives and tape volumes in an SMS-managed IBM tape library environment (automated or manual) for 3590 Model B emulation only. To do so, you need to specify at least one of these library device group (LDG) names in your JES3plex. An LDG is a predefined set of tape subsystems within a JES3plex.

LDKsssss

Includes any 3592 Model E05 device emulating a 3590 Model B within the library indicated by serial number sssss.

LDGdddd

Includes any D/T3592 Model E05 device emulating a D/T3590 Model B in any library in the JES3plex. dddd = 359K.

See z/OS JES3 Initialization and Tuning Reference for additional information on LDGs, JES3, and JES3plex.
