RE: [Ips] NOP during Discovery

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

Eddy,

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.

Thanks

 

Would it work to just use SendTargets=<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.

 

If so, can you talk that person into that?

 

Eddy

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.
Discovery being only a lightweight location mechanism it was decided that it is  not worth having it as a permanent alternative for a management interface.

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?

 

3.3 iSCSI Session Types

  iSCSI defines two types of sessions:

  a) Normal operational session - an unrestricted session.

  b) Discovery-session - a session only opened for target

     discovery. The target MUST ONLY accept text requests with the

     SendTargets key and a logout request with reason "close the

     session". All other requests MUST be rejected.

     The session type is defined during login with key=value parameter in

     the login command.
