    RE: FW: FW: iSCSI: support value of ?



    
    There was a potential proposal for extracting the eui, from the host, or if
    you will -- the platform name, which might be used by a Gateway Device, and
    that was for the gateway to ask with a keyword followed by the "?".  But we
    have not reached closure on any thing like that for now.

    Julian:
    
    I first brought up the subject of eliminating ? last December.
    Your reply is attached below.
    Perhaps this latest round of e-mail postings is enough to
    support my contention that ? should be eliminated??
    Thanks,
    Bob Russell
