Page 104 The transfer width is two the transfer width exponent bytes wide. The transfer width that is established applies to all logical units. Valid transfer widths for the DLT 7000 tape drive are 8 bits (m = 00h) and 16 bits (m = 01h). Values of m greater than 01h is reserved.
Page 105: Scsi Commands
This chapter describes the SCSI protocol features implemented in the DLT 7000 tape system. Note that the sections included in this chapter do not fully reiterate every ANSI SCSI message, option, and/or command code specification; the sections do describe the supported commands, messages, options, and error recovery procedures.
Page 106 The DLT tape drive does not act as an initiator on the SCSI bus. Therefore, the drive will not 1) generate unsolicited interrupts to the host, 2) initiate its own SCSI commands, or 3) assert bus reset. Linked commands are supported. Untagged queuing is supported.
