Hi, what probably is needed is to teach the kernel about your array and to make the kernel either scan all luns or ask the device which luns it has. Can you post the /proc/scsi/scsi entry for your array ? (only for the LUN0 is enough); that information is going to be needed to make a special entry for your array with either of the two behaviors..
