The reason? Maybe the controller > you're using, "PROMISE 2U-SAS-12-D2 BP 0107, LSI card" (as > you wrote) is not configured to represent the devices as > "normal" hard disks to the operating system? I don't know this controller, but I have seen a few lately that in the firmware/BIOS for the controller you would configure each drive as a RAID 0 SINGLE. Then they show up as a /dev node the way you'd expect. I wasn't used to this, as I was still used to just being able to configure the controller for JBOD and that was that. > Additional question: Have you loaded the driver that supports > your card (mfi, mpr, mpt, mps etc.) in /boot/loader.conf? > -Mike
