RE: how much "Desired Data Transfer Length" in R2T

[Nitin Dhingra <nitin.dhingra@dcmtech.co.in>]

Hi sastry,
What you specified is during negotiation, I am referring to after the
negotiation, when 
DataPDULength has been decided. But Later when R2T's needs to be send from
target, 
examples have been given in the draft that depicts one R2T is sent from the
target and it receives 
2 Data PDU's. It means that target specified more size than DataPDULength
in the R2T, on what 
basis did the target decide that.

Thanks,
nitin

Nitin,

I think  the "Desired Data Tranfer Length" field of R2T PDU  should be equal
to
the DataPDULength
value that the initiator has sent to the target during text parameter
negotiation. Since the DataPDULength
can be different in the two directions, the initiator sends this value to
the
target as DataPDULength=<value>.
So the initiator only  sends/receives a PDU having length less than or equal
to  the negotiated DataPDULength
(non-zero).

Any comments are welcome..
