Just upgrade to ESX4 and take advantage of ALUA-aware PSA for EVA! Then use round-robin load balancing which due to ALUA will only round-robin across the paths for the active controller, while being aware of the paths to the other controller which it can fail over to if the active controller paths are no longer available. See Best Practices for HP EVA family and vSphere 4: http://h20195.www2.hp.com/v2/GetPDF.aspx/4AA1-2185ENW.pdf
