Awesome! I just tried it on our test machine.
raidtest2# atacontrol status ar0
ar0: ATA RAID1 subdisks: ad8 ad10 status: READY
raidtest2#
Also, I updated a few other boxes that have
atapci0: <VIA 82C686 ATA100 controller> port 0xe000-0xe00f at device 7.1 on=
=20
pci0
and so far so good!
Also, what would you recommend for hot swapable trays ?
