			Appendix A Error Codes
Page A - 4			Summary
	Code	Name	Description
	21H	Unexpected	If a SCSI device unexpectedly goes to the bus free state, this code
		Disconnect	will be reported.
			If the device returns a bad status (status other than 0) in response to
			a Pass-through command, this code will be reported. The SCSI
			Status field of the Status Block will contain the Status Byte returned
			by the device (Busy, Reservation Conflict, Check Condition, etc.).
	23H	Unit Returned Bad	If the SCSI status is Check Condition, and the automatic request
			sense feature of the adapter is not inhibited, the Selected Sense Bytes
		SCSI Status
			fields of the Status Block will contain the Status Bytes returned by
			the device. These will further describe the Check Condition.
			If the automatic Request Sense feature is inhibited (with the IRS bit
			of the Flags-1 byte), the Selected Sense Bytes fields of the Status
			Block will contain zeroes.
	24H	Unexpected SCSI	This code is reported if the SCSI device being accessed enters a
		Phase Entered	phase that is unexpected for the command sequence issued.
			If an automatic Request Sense command results in fewer bytes
			transferred than required to satisfy the Selected Sense Bytes fields
	25H	Data Transfer	of the Status Block, this code will be reported. The Selected Sense
		Truncated	Bytes fields of the Status Block that have been truncated will contain
			value FFH to aid the host in determining which Selected Sense Bytes
			are valid.
			This code can be reported for either of the following reasons:
			1.) Certain conditions will arise that will force the adapter to assert
			RST on the SCSI bus in order to get to bus free. The SCSI command
			that was executing at the time of the RESET and any commands that
	27H	SCSI Bus Reset	were disconnected at the time of the RESET will report this error. A
			SCSI bus RESET is a last-resort measure that the adapter uses only
		Asserted or Detected	if all prior error recovery attempts to get the SCSI bus to a free state
			have failed.
			2.) The adapter detected a SCSI bus reset. The SCSI command
			currently executing and any commands that were disconnected at
			the time of the reset will report this code.
			For SCSI data transfer commands, if the SCSI device transfers an
	2BH	SCSI Invalid Data	odd number of bytes, then 1.) changes phases and/or disconnects,
			and then 2.) subsequently returns to the data transfer phase to
		Transfer Condition	continue the transfer, the RF3880 will abort the command and report
			this error.
			After executing a Message Pass-throughoperation of Bus
		Message Clear Queue Device Reset or Clear Queue, the adapter clears its internal queue
	31H	or Device Reset	of commands that were disconnected when the message was sent.
		Occurred	This code will be reported in the Status Block of each disconnected
			command that was terminated due to the message-only operation.
		State wrong for	This code is returned under these conditions:
			- Target Mode Enable command issued when Target Mode is already
	32H	Enable/Disable Target enabled.
		Mode Enable	- Target Mode Disable command issued when Target Mode is not
		Command
			enabled.
	33H	Selection Attempted	An initiator tried to select the RF3880 without an arbitration phase.
		Without Arbitration
			A message byte was received while in Target Mode. This message
	34H	Target Mode Message	byte is in the Message Byte Received field of the Selection Data
			Structure, or the Status Block. The Error Sequence field provides
		Received	additional information. The adapter will hold the SCSI bus waiting

for a response from the Host.

35H Target Mode Illegal Message Received

The adapter received and rejected an illegal message byte from the initiator. This message byte received is in the Message Byte Received field of the Selection Data Structure, or the Status Block. The Error Sequence field provides additional information. The adapter will disconnect and terminate the SCSI I/O process. This error is used to inform the Host of the action completed. The Host should prepare Sense Data.
