Adding a drive to an existing RAID5 Array.

I've added a new drive to an existing RAID5 configuration, expanded the Array with the RAID Admin utility. It recognizes it, looks good, all green. However, I'm at a loss on how to make the OS recognize the expanded array size. I'd very much like to get the new drive space available for users. I think I've done this about 2 years ago, but can't find my documentation for it. There used to be a KB article on it, but it was nearly impossible to find with out the help of support.

Can someone direct me at that, or walk me through what I need in order to get the added drive space in the array recognized by the server OS?

MacBook Pro 15" 2.53 GHz Intel Core 2 Duo, Mac OS X (10.5.7), 4G RAM

Before expanding and slicing you'll need to do a backup, here's the link.

The app isn't available anymore. Support said it was there at one time, but was taken down. The Knowledge Base still has 2.0 help/support articles in it:

http://support.apple.com/kb/index?page=search&q=RAID%20Admin%202.0

But, either way, 1.5.1 is the working version out there, but because I was finding 2.0 in the KB, I was confused. You are right, there is no working version 2.0 at this time. (I think there's a 1.5.2 beta, but that a horse of a different color.)
