RE: iSCSI: minor conflict introduced by C bit

["Julian Satran" <Julian_Satran@il.ibm.com>]

In fact for 11.9 the text will be:

Target portal group tag is a 16-bit numerical-value that uniquely identifies a portal group within an iSCSI target node. This key car-ries the value of the tag of the portal group that is servicing the Login request. The iSCSI target returns this key to the initiator in the first non-empty Login Response PDU (where empty responses may be required by Login Requests with the C bit set to 1). 

11.4 refers to the Sendtargets response that will be presented whenever and has no other apparent conflict with C.

Thanks Pat - I think that 3 is acceptable and keeps current semantics unchanged.

Julian,
 
I have noticed a minor conflict of the C bit with existing text.
 
11.4 and 11.9 require the target to return TargetName and TargetPortal group in the first Login Response PDU but the new text on the C bit in 4.2 requires the target to return an empty response if the C bit is set. Therefore, if the C bit is set on the first Login Request PDU, the target will have conflicting requirements on it. 
 
One could resolve this by:
1) Specify that the C bit MUST NOT be set in the first Login Request PDU; or
2) Allow declarations to be sent in PDUs when the other side has the C bit set; or
3) Change the requirement in 11.4 and 11.9 to be the response to the first Login Request PDU with the C bit set to zero.
 
Regards,
Pat
