DLTtape Application Note
This personality is an OEM-based ANSI SCSI-2 variation. It is the standard
personality shipped with the drive. This code is used for DLT tape unit
installations on most platforms.
This personality is an OEM-based ANSI SCSI-1 variation and is used only for
those applications that require SCSI-1 features. Only available for DLT2000,
DLT2000XT, and DLT4000.
This personality is an emulation of the IBM 7208, Model 2 and is used only for
DLT tape unit installation on an AS/400. This personality is not available for
DLT7000. Only available for DLT2000, DLT2000XT, and DLT4000.
This personality is the standard SCSI-2 implementation with one-way
communication protocol over RS422 port. Only by the library OEM customers use
this code. The SCSI implementation is identical to OEM-1.
This personality allows DLT emulation of SCSI-2, 8mm tape drive (EXB-8505)
when attached to HP9000/800 systems. HP's fbackup and frecover are not
supported with this code. Although provided for backward compatibility, OEM-1 is
recommended over this code. Only available for DLT2000, DLT2000XT, and
DLT4000.
This personality allows DLT emulation of HP 7980S when attached to
HP9000/800 systems. Earlier code revisions emulate HP35450A. Although
provided for backward compatibility, OEM-1 is recommended over this code. Only
available for DLT2000, DLT2000XT, and DLT4000.
