If dmesg itself returns none of the startup info, you can look in /var/log/dmesg.[today|yesterday]. /usr/sbin/pciconf can tell you what controller(s) may be attached. A proper RAID will show up as a single device, just like any hard drive (but different). It does seem odd to me that a (supposed) RAID would show up as /dev/ad4. Possibilities: Your RAID really is on /dev/ad4 and /dev/ad6 is something unexplained. Your RAID controller is unsupported in 5.x and not Doing The Right Thing but somehow still (kind of) working as a normal [S]ATA controller. Your RAID controller is unsupported in 5.x and your hosting company realised this and wired the shebang up as a normal [S]ATA controller because they couldn't get FreeBSD to install otherwise. There is a RAID controller and there are two disks connected to it, but the controller was not set up correctly. There is a RAID controller and there are two disks connected to some other controller which might lead to some interesting phone calls. Your remote hosting company put a RAID with two disks in some random machine and someone else is complaining on some other list about the inverse of your problem. -- --
