Bus device
reset 0Ch The initiator instructs the autoloader to reset all
of its current I/O operations for all initiators. The
autoloader releases the SCSI bus into the bus
free phase, with no operations pending for any
initiator, and performs a soft reset. x
Identify 80h or
C0h This message establishes a physical path
connection between the initiator and the
autoloader. It also indicates whether disconnect
is supported and the LUN for which the
command is intended. The autoloader supports
a LUN of 0. x x
Table 6 SCSI messages supported by the autoloader
1) autoloader to initiator
2) (initiator to autoloader)
3) The autoloader negotiates down to narrow and asynchronous data transfer. The autoloader never initiates
negotiations for either
11.2.2 SCSI Commands
The initiator sends commands to the autoloader to request an operation. The following table lists and
briefly describes the SCSI commands supported by the autoloader.
NOTE:
For information about tape drive commands, see the tape drive documentation.
When you issue this
command ... OP
Code The autoloader does this ...
INITIALIZE ELEMENT STATUS
(6 bytes) 07h Checks all element addresses for cartridges.
INITIALIZE ELEMENT STATUS
WITH RANGE (10 bytes) E7h Checks all element addresses for cartridge. This
command is implemented for emulation
compatibility only. The autoloader treats this
command exactly as if it were an INITIALIZE
ELEMENT STATUS command.
INQUIRY (6 bytes) 12h Sends information about its parameters,
including the autoloader product identification
and serial number, to the initiator.
LOG SELECT (10 bytes) 4Ch Manages statistical information maintained by the
autoloader.
LOG SENSE (6 bytes) 4Dh Returns statistical and condition information to
the initiator.
MODE SELECT (6 bytes) 15h Accepts changes to element address
assignments and operating parameters from the
initiator.
MODE SENSE (6 bytes) 1Ah Reports its operating mode parameters to the
initiator.
MODE SELECT (10 bytes) 55h Accepts changes to element address
assignments and operating parameters from the
initiator.
