z/OS software support for the 3592 Model J tape drive

Use z/OS® software with the 3592 Model J to increase your data storage capacity with the IBM System Storage family of tape media and the EFMT1 recording technology. Table 1 describes z/OS DFSMS components, Multiple Virtual Storage (MVS™) Device Allocation, Environmental Recording, Editing, and Printing (EREP), DFSORT, and JES3 that provide software support for the 3592 Model J.

Table 1. Components that provide software support for the 3592 Model J tape drive
Component	Function
AMS	AMS allows the use of the EFMT1 recording technology and IBM System Storage family of tape media for volumes as well as the printing and displaying of information about the recording technology and media type.
Device Services	Device Services manages the IBM System Storage Tape System 3592 devices.
DFSORT	DFSORT works without change with the IBM System Storage Tape System 3592 devices.
EREP	EREP provides device type information when formatting LOGREC records.
DFSMShsm	DFSMShsm allows the use of 3592 devices and media for DFSMShsm-related activities. Customers can also choose to limit the data written to the first 60 GB (the optimally scaled performance capacity) of the IBM TotalStorage Enterprise Tape Cartridge (MEDIA5) by using the data class performance scaling attribute. This option is not available on MEDIA6, MEDIA7, or MEDIA8 tape cartridge media.
ISMF	ISMF allows the use of 3592 devices and media in the ISMF Data Class Application, Mountable Tape Volume Application, and the Tape Library Management Application. In addition, the data class performance scaling attribute, if selected, allows the user to limit the amount of data written to each tape. This applies to MEDIA5 tape cartridges. For 3592 Model J, the limit is the first 20% (60 GB physical) of tape media.
z/OS Multiple Virtual Storage (MVS) Allocation	z/OS MVS Allocation allows the use of the EFMT1 recording technology and IBM System Storage family of tape media when using the Dynamic Allocation Text Unit DALINCHG.
OAM	OAM tape library support allows the use of the EFMT1 recording technology and IBM System Storage family of tape media in the IBM 3494 Automated Tape library and in the IBM manual tape library. OAM object tape support allows the use of 3592 devices and media for object-related activity. Customers can also choose to limit the data written to the first 60 GB (the optimally scaled performance capacity) of the IBM TotalStorage Enterprise Tape Cartridge (MEDIA5) by using the data class performance scaling attribute. This option is not available on MEDIA6, MEDIA7, or MEDIA8 tape cartridge media.
OCE/IFGOJES3	OCE/IFGOJES3 allows the use of the EFMT1 recording technology and IBM System Storage family of tape media in the stand-alone environment and the tape library environment. New devices can also be used in a tape library that is JES3-managed.
DFSMSrmm	DFSMSrmm allows the use of the EFMT1 recording technology and IBM System Storage family of tape media. DFSMSrmm records the volume capacity for a volume including the volume capacity when performance scaling is specified. This applies to the IBM TotalStorage Enterprise Tape Cartridge (MEDIA5).
SMS	SMS allows the use of the EFMT1 recording technology and IBM System Storage family of tape media. You can specify the data class performance scaling attribute for the IBM TotalStorage Enterprise Tape Cartridge (MEDIA5). This option is not available on MEDIA6, MEDIA7, or MEDIA8 tape cartridge media.
