g. SAVE DATA POINTER
When rejecting this message for disconnection of the SCSI bus, the IDD continues the
currently executing command without disconnection as the DISCONNECT message is
rejected.
h. SIMPLE
When this message sent next to the IDENTIFY message at reconnection is rejected, the IDD
immediately enters the BUS FREE phase and terminates the command which has requested the
reconnection abnormally. No further reconnection for the command is attempted, and the IDD
does report the command completion (status and message) for the aborted command. Then,
the IDD creates the sense information with Sense Key/Additional Sense Code of "ABORTED
COMMAND [=B]/Message Error [=43-00]".
i. SYNCHRONOUS DATA TRANSFER REQUEST
The IDD assumes that the INIT does not support the synchronous transfer mode, and continues
the command execution using the asynchronous transfer mode.
j. WIDE DATA TRANSFER REQUEST
The IDD assumes that the INIT does not support the wide transfer mode. The IDD sets the
data transfer width to the 8-bit mode and the asynchronous mode, and continues command
execution.
k. PARALLEL PROTOCOL REQUEST
The IDD assumes that the INIT does not support the DT DATA IN/OUT transfer mode. The
IDD sets the data transfer mode to the 8-bit width mode and the asynchronous mode, and
continues command execution.
(7) Reselection timeout
If the INIT does not respond within the specified time period (Selection Timeout Delay: 250 ms)
in the RESELECTION phase, the IDD considers that a reselection timeout has occurred. In this
case, the IDD executes timeout processing of RESELECTION phase based on the protocol of
SCSI bus phase, and it enters the BUS FREE phase. (For the timeout processing, see Section
1.6.4.)
After entering the BUS FREE phase, the IDD waits at least 200 s and retries the reselection.
If the reselection retries have failed, the IDD abnormally terminates the command which is
requiring the reconnection. In such case, the command is never reconnected and the IDD does not
report the command completion (the status and message). The IDD generates the sense data which
indicates the "ABORTED COMMAND [=B]/Select/reselect failure [=45-00]" sense key/sense
code.
