User's Guide

RESERVE UNIT and RELEASE UNIT by Logical Unit Number
are supported, as are third-party reservations. Extent
reservations are not supported.
The RECEIVE DIAGNOSTIC RESULTS and SEND DIAGNOSTIC
DATA commands implement vendor-unique pages to test the
drive during the manufacturing process. It is recommended
that initiators specify only the non-page format variants of
these commands (PF=0), except for page 0x40.
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.

SCSI Pointers 3
SCSI architecture provides a set of three pointers (called saved pointers)
for each I/O process. The three pointers are: Command, Status, and Data.
When an I/O process becomes active, the three saved pointers are copied
Rewind 01h
Send DiagnostiC 1Dh
Space 11H
Test Unit Ready 00h
Verify 13H
Write 0Ah
Write Buffer 3bH
Write Filemarks 10h
Note: Relative Addressing is not supported by the tape drive.
Therefore, in all I/O commands, the RelAdr bit must be 0.
