Note: The initiator may send the I N I T I A T O R D E T E C T E D E R R O R message as a result of an
initiator detected SCSI Bus parity error or an internal error.
Retry MESSAGE IN phase
−
The retry will be caused by the receipt of a MESSAGE PARITY E R R O R message immediately
following a MESSAGE IN phase.
Note: The Initiator may send the MESSAGE PARITY E R R O R message as a result of an Initiator
detected SCSI Bus parity error during the Message In phase.
Receipt of multiple Identify message
−
The initiator is allowed to send multiple I D E N T I F Y messages out in order to toggle the
disconnect/reconnect
permission bit. This may be used to selectively enable or disable
disconnect/reconnect permission during portions of a command. Note that this function does not
effect the operation of the Forced Disconnect function.
MESSAGE R E J E C T during Target Disconnection
−
If the Initiator rejects the SAVE DATA P O I N T E R message, the file will disable
disconnect/reconnect permission. This is equivalent to receiving an I D E N T I F Y message with bit 6
equal to zero. This will cause to file to inhibit the pending disconnection.
−
If the initiator rejects the DISCONNECT message, the file will not disconnect but may attempt to
disconnect at a later time.
This function may be used to selectively disable disconnection during
portions of a command.
