As far as I know, this is not possible since any RAID setup will need some bytes of Metadata at the start or end of a partition/device. BTW: If the 6i/R is similar to the 5i/R, do not trust it's RAID capabilities but use software RAID instead. This is just an el-cheapo RAID controller without any of the advanced features of "real" hardware RAID. We're suffering from an 5i/R on one of our machines - it's performance is abysmal. You don't need to reinstall if you boot from a CD, then setup software RAID devices on the new disk (with one missing device), copy everything over, then create the devices on the old disk and let the software RAID do the sync. If you've got LVM in place, things will get easier.
