That is still the case at the moment. You can use a hardware raid
system which presents the raid area to the OS as a synthetic disk
drive, but you can't (yet) use vinum(8) or other OS level volume
management sytem reliably.
The reason why is fairly simple: the system bootstap mechanism doesn't
understand raid systems well enough to be able to operate correctly.
Although the reason is simple, the solution is apparently not. It's a
work in progress.
Cheers,
Matthew
