    Venky,

    I was looking through some old e-mail and found your message. It didn't seem as though anyone had replied, so I thought I'd take a stab at it.

    The PPDT S/W would decide based on the availability of initiator or target functionality on the destination device. If the destination was a target, the PPDT S/W would login using the local SBP-2 initiator. If the destination was an initiator, the PPDT S/W would use reverse login and the local SBP-2 target. If the destination had both target and initiator, the PPDT S/W could use either the local SBP-2 initiator or the local SBP-2 target.
