Sorry i didnt realise this got posted as i thought i got an error message saying something like i didnt have permission to post.
With regards to the user manual i did originally look there but missed the second section on configuring the raid 10.
On the 3ware 9650 all you had to do was select 4 drives and then choose the option for raid 10.
On this controller the two step process of setting up two raid 0 sets and then combining them into a raid 1 wasnt obvious to me due to my previous experience with the 9650.
But all the same, thank you for your reply!
