    maybe check and compare i/o statistics on your HBAs using 'fcstat fcsX' command - you could see somethink like:

    Transmit Statistics Receive Statistics
    Frames: 141323710 94168668
    Words: 53312362752 12522211072
    lspath -F'status name path_id parent connection'
    shows also paths priorities. on vscsi envronment path with id 0 holds transfer at the moment (when is in Enabled state of course).

    The 'iostat -m -d hdiskN 2' shows you every 2 sec. which path of hdiskN is really active.
