RE: iSCSI: LUN in Data-out and NOP PDU's

[Sanjay Goyal <sanjay_goyal@ivivity.com>]

Hi 

to be very specific on the question,

 Nop-out and Nop-in PDUs are used by Initiators and Targets also to ping each other. If a target is trying to ping the Initiator, why does it need to use a particular combination of TTT and LUN i.e. the "virtual target". 

Should we really use TTT and LUN pair for a function which is for target and not for "virtual target"  OR am i missing something.

 

Regards

Eddy,

It was felt that TTT management could be kept local to the LU or group of LUs (no requirement to be unique on target).
The combination LU and TTT is used instead. That enables groups of entities to form a "virtual target".

What is the LUN for in Data-out and NOP-out PDU's?

I assume the LUN in Data-out could be used for steering but I don't know what the LUN in NOP-out PDU's is for.
