TMF for a write with only unsolicited data

Suppose:

1) a TMF is not a TASK REASSIGN

2) the TMF is for a write command

3) the write command only has unsolicited data



I think this is saying the WSV is set to 0 for this case. Is that correct?



If so then I think the 3rd bullet item in 7.3.3 needs to say "if allocated" since a write with unsolicited only will also have a DataDescriptorOut.



Or am I wrong in that the TMF would have the DataDescriptorOut for a write with only unsolicited data?






   WSV - Write STag Valid flag: 1 bit 

 

        This flag indicates the validity of the Write STag field of the 

        iSER Header.  If set to one, the Write STag field in this iSER 

        Header is valid.  If set to zero, the Write STag field in this 

        iSER Header MUST be ignored at the receiver.  The Write STag 

        Valid flag is set to one when there is solicited data to be 

        transferred for a SCSI Write or bidirectional command, or when 

        there are non-immediate unsolicited and solicited data to be 

        transferred for the referenced task specified in a Task 

        Management Function Request with the TASK REASSIGN function.



7.3.3  Task Management Function Request/Response 



   *  It MUST use the ITT as specified in the Referenced Task Tag from 

      the Task Management Function Request PDU to locate the existing 

      STag(s), if any, in the Local Mapping(s) that associates the ITT 

      to the local STag(s). 

 

   *  It MUST invalidate the existing STag(s), if any, and the Local 

      Mapping(s) that associates the ITT to the local STag(s). 

 

   *  It MUST allocate a Read STag for the I/O Buffer as defined by the 

      qualifier DataDescriptorIn if the Send_Control Operational 

      Primitive invocation is qualified with DataDescriptorIn.
