RAID 1 Cant Find Mirror!!

I have two drives in a Dell server. They are both 68GB a peice. I setup RAID 1 using dell Array manager, ran windows server 2003 setup ect…, I then split the now 68GB total that was left into 3 logical drives. Now I was just wondering, how do you know this is working? Where can you check to see the Mirror Drive?

Am I missing something somewhere?
I thought it was under disk manager under computer management. I only see the primary partition. I thought it was also suppose to show the mirror volume. Any help is much appreciated!
