I wish to connect to a scsi external storage array, that has two interface cards, via two Host Bus Adapters on my linux box (in an attempt to increase throughput). I'm using the stock qla2300 drivers and can see both cards when I do a 'cat /proc/scsi/scsi' but I've only been able to see the array (and it's associated LUNs) through one HBA though. I've done some research and came across the multipath concept and being not entirely sure of what it is, was wondering if this is the direction I should continue to pursue in order to accomplish this? Or, if not, does anyone have advice as to what I need to do to get this to work (if at all possible)? Thanks in advance! Chris
