I'm installing FreeBSD 8.0 on a server that has hardware SATA Raid.
I'm just wondering. What is the difference between these devices.
i.e. ar0, da0, ad4, ad5 I take it that ad4 & 5 are my two disks. Somehow the OS can see them individually even though it's one logical mirrored drive.
Should I be installing it onto ar0 or one of the adX disks. What is da0? it's smaller than the others. ar0 is not some kind of software raid device is it?
Just want to make sure I don't mess this up right from the get go.
