(1) FCP RESID UNDER [PL:WO2/B2/bit3]
In case of
FCP_DL (FCP_CNMD) > (transferred data byte
velocity based on CDB)
Residual Counter = FCP_DL – (transferred data
byte velocity)
(2) FCP RESID OVER [PL:WO2/B2/bit2]
In case of
FCP_DL (FCP_CNMD) < (transferred data byte
velocity based on CDB)
Residual Counter = FCP_DL – (transferred data
byte velocity)
(3) FCP SNS LEN VALID [PL:WO2/B2/bit1]
When this bit is 1, the field of Length of Sense
Information (FCP_SNS_INFO) is valid and
FCP_RSP frame includes the FCP Sense
Information field.
(4) FCP RSP LEN VALID [PL:WO2/B2/bit0]
When this bit is 1, the field of Length of
Response Information (FCP_RSP_INFO) is
valid and FCP_RSP frame includes the FCP
Sense Information field.
(5) SCSI Status [PL:WO2/B2/bit0]
Refer to Section 2.2 Status Byte.
(1) Response Code (FCP RSP CODE)
[PL:W06/B3]
Supporting Response Code below.
00h: Task Management Function Complete or
No Failure.
01h: FCP DATA lingth different than Burst
Length.
02h: FCP CMND fields invalid.
03h: RO in the data frame header mismatch
with FCP XFER RDY DATA RO.
04h: Task Management Function not support.
05h: Task Management Function failed.
