Just had a flick through README.aic7xxx in /usr/src/linux/drivers/scsi.
I found this:-
AIC-7810
Bus Types
----------------------------
R - Raid Port busses are not supported.
The hardware RAID devices sold by Adaptec are *NOT* supported by this
driver (and will people please stop emailing me about them, they are
a totally separate beast from the bare SCSI controllers and this driver
can not be retrofitted in any sane manner to support the hardware RAID
features on those cards - Doug Ledford).
So I guess that raid is not supported with the standard aic driver.
(This was from 2.2.9 - not the latest, but it works for me)
