DESCRIPTION
Performs either a rewind operation or a rewind and
unload operation.
Requests that result data generated for a previous
SEND DIAGNOSTIC command be sent to the initiator.
Requests the target to perform diagnostic tests on itself,
or on the attached peripheral devices.
Causes the tape unit to position to a specific logical
location.
Causes 20 bytes to be sent from the target to the initia-
tor. The 20 bytes are a report of the position of the tape
unit and information about blocks stored in the buffer.
Used in conjunction with the READ BUFFER com-
mand as a diagnostic function for testing target memory
and the SCSI bus integrity.
Used in conjunction with the WRITE BUFFER com-
mand as a diagnostic function for testing target memory
and the SCSI bus integrity.
Used to modify the operating definition of the selected
target with respect to all initiators. This command is
used in conjunction with the Inquiry command to
change (and optionally save) parameters that affect the
operation of the target.
Provides a means for the initiator to retrieve informa-
tion maintained by the target about the supported densi-
ties for the MTU logical unit.
Note: Support of this command is configuration depen-
dent. In order for this command to be supported, FT4
(Feature Mode 4), bit 6 (40h) must be set to 1. See the
command description for more information.
Provides a means for the initiator to manage statistical
information maintained by the target about itself and
attached logical units.
Provides a means for the initiator to retrieve statistical
information maintained by the target about itself and
attached logical units.
Used to check the controller's data and control path.
Used to display a message on the operator panel of the
tape drive or cartridge loader (if installed.)
