Initiator Pass-through Status Block Format
SCSI Status
When a SCSI device completes a command, during the STATUS phase of the
SCSI bus it returns a SCSI Status Byte Code to the adapter. The adapter reports
that value in this field. The field has these bit meanings:
RES
- SCSI reserved.
Status Byte Code
- Implementation of these bits is required for all devices
that adhere to SCSI specifications. See the table below for information about
what they mean.
Further information about the Status Byte Code can be found in the SCSI, SCSI-
2, or SCSI-3 specification.
SCSI Status Field during Unexpected SCSI Phase
In the event that the adapter encounters an unexpected SCSI phase it does two
things: posts an error (24H) in the Error field of the Status Block, and reports
the phase encountered in the last three bits of the SCSI Status field. The bits
correspond to the MSG, C/D, and I/O signals. At the time of an Unexpected
SCSI Phase Encountered error, the SCSI Status field has the following bit-
meaning:
I
- I/O (Input/Output) Signal from Target
C
- C/D (Control/Data) Signal from Target
M
- MSG (Message) Signal from Target
X
- May be either 0 or 1
