FUJITSU M3097G - Manual (Page 116)

When this scanner receives the INITIATOR DETECTED ERROR message, this
scanner enters the MESSAGE IN phase and sends the RESTORE POINTERS
message to the initiator. Then this scanner returns to the original phase and
makes a retry.
After issuing the RESTORE POINTERS message, this scanner takes action as
shown in the following table.
ATN detection
phase
Action
SELECTION Moves to the BUS FREE phase
COMMAND Discards the CDB already received and returns to the
COMMAND phase
DATA OUT Discards the data already received and returns to the DATA OUT
phase
DATA IN f When transferring image data, enters the DATA IN phase.
If the memory option is provided, transfers image data again.
If no memory option is provided, moves to the STATUS phase
(Check Condition) Æ MESSAGE IN phase (Command
Complete) Æ BUS FREE phase and keeps the sense key X©Bπ
(Aborted Command).
f When transferring inquiry data or sense data, returns to the
DATA IN phase and transfers data again
STATUS Returns to the STATUS phase and sends the status byte again
MESSAGE OUT Ignores this message (does not issue the RESTORE POINTERS
message)
MESSAGE IN Returns to the MESSAGE IN phase and sends the message byte
again
(3) ABORT (X©06π) : MESSAGE OUT phase (initiator Æ target)
The initiator requests the target to clear the input/output operation of the specified
I/O unit (i.e., the input/output operation ordered by the initiator that issued this
message) and to move to the BUS FREE phase. Input/output operations ordered by
other initiators are not affected.
If a logical unit is not identified before the ABORT message, the target merely
moves to the BUS FREE phase.
If no operation to be cleared, an error does not occur.
The initiator does not intend to issue another message by activating ATN before it
deactivates the ACK of the ABORT message.
