Eddy,=20

I think that they realized that already and are content. NOP is somewhat =
richer in that in a "storage router" NOP might reach the end-point while =
SendTargets will probably not.  In any case the text is unequivocal =
about NOP.=20

Thanks=20
 =20
Would it work to just use SendTargets=3D<nothing> instead of NOP? If =
there is a target for the discovery session, it would respond with just =
the target name. If there are no targets for the discovery session, the =
target would still respond but with 0 for the DataSegmentLength.=20
 =20
If so, can you talk that person into that?=20

It is not allowed in discovery - There was a long discussion with one =
party insisting on having NOP as a way of keeping the discovery session =
alive.=20
Discovery being only a lightweight location mechanism it was decided =
that it is  not worth having it as a permanent alternative for a =

I have found that at least one initiator is doing a NOP-out during =
discovery phase. But the spec says that isn't allowed. Am I =
misunderstanding something?=20

3.3 iSCSI Session Types=20
  iSCSI defines two types of sessions:=20
  a) Normal operational session - an unrestricted session.=20
  b) Discovery-session - a session only opened for target=20
     discovery. The target MUST ONLY accept text requests with the=20
     SendTargets key and a logout request with reason "close the=20
     session". All other requests MUST be rejected.=20
     The session type is defined during login with key=3Dvalue parameter =
in=20
     the login command.=20
