I found this on the net: quote from: http://serverfault.com/questions/275875/raid-bus-controller-intel-corporation-82801jir-ich10r-sata-raid-controller "ICH10R-based RAID controllers are so called fake- or software-RAID controllers, the OS needs to do all the work." What you have on 8.3 might be a software raid, one way to get it: gmirror label ar0 ad4 gmirror load gmirror insert ar0 ad6 You now have ``/dev/mirror/ar0'' as device node for your software RAID, check: gmirror status > pciconf -vl on FreeBSD 8.3: > atapci0@pci0:0:31:2: class=0x010400 card=0x11501734 chip=0x3a258086 > rev=0x00 hdr=0x00 > vendor = 'Intel Corporation' > device = 'SATA RAID Controller' > class = mass storage > subclass = RAID > > dmesg output on FreeBSD 8.3: > # dmesg|grep ar0 > ar0: writing of DDF metadata is NOT supported yet > ar0: 952720MB <DDF RAID1> status: READY > ar0: disk0 READY (master) using ad4 at ata2-master > ar0: disk1 READY (mirror) using ad6 at ata3-master > > As far as I understand (while I don't have that much FreeBSD > experience), amr is the appropriate driver for this controller.
