Moving a raid array

[grumblenz]

I had a 10.04 setup with a Silicon Image 3114 raid controller and a TX4310 Controller with two raid 1 arrays. Built a new machine (New 10.4 install), moved the entire array from one machine to another with NO changes at all. All good so far BUT, the new machine (Using Disk Utility) shows 2 controllers and 4 drives - how do I ensure they are both working as a raid array because they seem to be working separately. I've only been on Ubuntu for 3 months spare time so please don't assume too much knowledge !! thanks
