Target Selection Data Structure Page 6 - 13

Error Sequence Code - The Error Sequence Code tells you, according to

the following table, where in the selection process an unrecoverable error

occurred, or a Message Byte was sent from the initiator. Some of these codes

are not possible due to a selection, but may be reported in a Target Mode

Response command Status Block.

Identify Message Received

This byte contains the last Identify message that was received from the initiator.

This byte includes the logical unit number (LUN) of the target being selected.

If the Error Sequence Code is 5, or the Error field is 33H, this field is invalid.

Initiator Identifier

This byte contains the SCSI ID of the initiator that selected the adapter. If the

Error field is 33H, this field is invalid.

Command Descriptor Block Length

This byte indicates the number of command bytes that were received from the

initiator, and have been passed on in the CDB fields of the Target Selection

Data Structure. If the CMD bit is clear (in the SCSI Flags field), this field is

invalid.

Message Bytes Received

This byte contains a SCSI message byte received from the initiator. If the MSG

bit is clear (in the SCSI Flags field), this field is invalid. Also, the value of the

Error Sequence Code must be considered when examining the Message Byte.

Queue Tag Identifier

This byte contains the queue tag identifier assigned to this SCSI command by

the initiator. If the Queue Tag message is 0H, this field is invalid (no queue tag

was received).

Queue Tag Message

This byte contains any Queue Tag message received from the initiator.

Sequence Description
