[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Question On R2T Behaviour?Hi all, On page 75 of iSCSi 0.8 revision " The data length of the DATA PDU MUST *not exceed* the desired data transer length specified in the R2T. If the R2T is answered with a sequence of data PDUs the buffer offset and Length must be within the range of those specfied by R2T, the last PDU SHOULD have the F bit set to 1. The data-out PDU ordering is goverened by DataPDUInOrder." My question is if the data length of the DATA PDU is less than the desired data transfer length and the F bit is set, what should be the behaviour of the target. For the sake of this discussion let us assume DataPDUInOrder to be set to Yes. 1. It looks intutive that target may send another R2T with different sequence number and collect the data initially that the host was not able to send for the previous R2T request. Or 2. It is an error that need to be detected by target that the host was not able to fully satisfy the R2T request sent by the target in the first place. Please let me know what is the right behaviour and should this be documented in the specification if it is not already documented. If it is documented may be i missed reading this, please point to me where it is defined. Thanks sureshtk
