1.9 FC-4 Device Data
C141-C008 1-93
(4) Type
SCSI FCP frame uses 08h.
(5) F_CTL.. (Frame Control)
− Set 980000h for the FCP_RSP
(Responder of Exchange, last sequence of exchange, last data frame of
sequence.)
(6) SEQ_ID.. (Sequence Identifier)
− The drive responds by FFh.
(7) DF_CTL.. (Data Field Control)
Set 00h because no optional header is used.
(8) SEQ_CNT.. (Sequence Count)
− It is responded 0000h because it is used single frame sequence.
(9) OX_ID.. (Originator Exchange Identifier)
− The drive responds the OX_ID of FCP CMND received from the
initiator.
(10) RX_ID.. (Responder Identifier)
Set FFFFh to indicate that RX_ID is unused.
(11) Parameter
Unused the parameter in the FCP RSP and 00000000h replied.
The payload field of the FCP RSP is defined below.
Word xx and byte y of the payload are represented by [PL:Wxx/By].
(1) FCP CONF REQ [PL:W02/B2/bit4]
The drive ignores this bit.
(2) FCP RESID UNDER [PL:W02/B2/bit3]
In case of
FCP_DL (FCP_CNMD) > (transferred data byte velocity based on CDB)
Residual Counter = FCP_DL – (transferred data byte velocity)
(3) FCP RESID OVER [PL:W02/B2/bit2]
In case of
FCP_DL (FCP_CNMD) < (transferred data byte velocity based on CDB)
Residual Counter = (transferred data byte velocity) – FCP_DL
