The card appeared to work ok (as evidenced by verbose boot messages but no disk(s) was seen. Finally was able to see disk with a 'camcontrol rescan 1:0:4' command. Previous 'camcontrol rescan all' and 'camcontrol rescan 1' failed to see disk. (and obviously not seen at boot time). I did not set the SAN up but from a cursory examination: The SAN has two controllers and two 'logical' raid 5 devices. One controller is connected to a Sun box which sees c1t0d[0-3] and the 4th lun appears to be given over to the second controller for the FreeBSD box. I assume this means that CAM does not probe all LUN's if no device at LUN 0 or sys/cam/cam_xpt.c has quirk entry for device that disables LUN probing. There is quirk for {"HITACHI", "DK31*"} but the SAN reports as Hitachi DF600F (I think, sorry its at work and I cannot access it currently) so the second case shouldn't be a problem. Am I reading this correctly? thanks -- tonym
