SCSI COMMAND DESCRIPTIONS
The SCSI commands are presented in alphabetical order. Each command starts
on a new, odd-numbered page. Because information about a particular command
may span multiple pages, the command name is repeated, in Italics, at the top of
every page that concerns that command. Blank pages in the chapter can be used
for note-taking.
The SCSI command descriptions that make up the rest of Chapter 5 contain
detailed information about each command supported by the Quantum DLT 4000
tape drive. Fields common to many of the SCSI commands are supported as
follows:
Name of Field:
How Field is Supported in SCSI Commands:
Logical Unit
Number
LUN for tape drive is 0.
Reserved
Reserved bits, fields, bytes, and code values are set aside for future
standardization and must be set to 0. If the drive receives a
command that contains non-zero bits in a reserved field or a reserved
code value, the command is terminated with a CHECK CONDITION
status and the sense key is set to ILLEGAL REQUEST.
RelAdr
Relative Address. Unused.
Explanations for those common fields are not repeated for every command in
which they appear.
Throughout this manual, multiple bytes that contain information about specific
command parameters are portrayed as shown in the example of the Parameter
List Length field (bytes 7 and 8) of the Log Select command shown as follows:
