Barry,

The intent of the draft is 2.
I did not require the pieces to be strictly "in order" (no need to).

Subject:  clearification on intent of last sentence




Julian,
The description of R2T in 02 reads as follows...

"An R2T MAY be answered with more than iSCSI Data-out PDU with
   matching Target Task Tag. If an R2T is answered with a single Data
   PDU the Buffer Offset in the Data PDU MUST be the same as the one
   specified by the R2T and the data length of the Data PDU must not
   exceed the Desired Data Length specified in R2T. If the R2T is
   answered with a sequence of Data PDUs the Buffer Offset and Length
   must be within the range of those
   specified by R2T and the last PDU should have the F bit set to 1; the
   Buffer Offsets and Lengths for consecutive PDUs SHOULD form a
   continuous range."

I would like to have the intent of the last sentence verified.
Interpretation 1 is: The initiator must send a sequence of PDUs such that
for each PDU 1..N, the offset (O) and the length L of the "i"th PDU is as
follows: O(i) = O(i-1)+ L(i-1)

Interpretation 2 is: After the sequence of N PDUs have been sent they shall
have formed a continuous range such that no gap exists between O(1) and
0(N).

I believe that your intent is 1 but I would like you to verify that
interpretation 1 is the intent of the draft.
