Message In Support
(Parallel SCSI only)
Message Parity
Error
09h The initiator has detected a parity error in a message. The drive will retry
the message. (See “ “Message In Support (Parallel SCSI only) ” below for
details).
If the message is received immediately after an Identify message or after
the Command Complete message has been sent, the drive will go Bus
Free.
Message Reject 07h This message is sent when the initiator does not support a message sent by
the drive or that the message is inappropriate. If the message being
rejected is Disconnect, Synchronous Data Transfer Request or Wide Data
Transfer Request, the operation continues without those features. For all
other messages, the message is treated as an Abort message.
If the message is received during a Command, Data or Status phase,
immediately after an Identify message or after the Command Complete
message has been sent, the drive will go Bus Free.
No Operation 08h This message has no effect and is ignored.
Name Code Support
Command Complete 00h This message is sent by the drive at the end of the status phase to
indicate that a command is complete. Once the message is sent, the
drive releases the bus and goes to Bus Free.
Disconnect 04h This message is sent by the drive to indicate that it is about to disconnect
from the bus and go to Bus Free. During a Data phase, it is always pre-
ceded by a Save Data Pointers message. If a Message Reject message is
received in response to this message, then the disconnect is prevented.
Extended Message 01h See “Extended Message Support” below.
Identify 8Xh The Identify In message is sent to the initiator during reconnect to
indicate which Logical Unit is reconnecting.
