Adding Raid to an existing Install

[jt at camalyn.org]

hi List,

I'm hoping that someone can help.

I have in total 3 IDE drives.

1 IDE drive I call the OS drive and I have installed Opensuse 11.1 onto
that.

I've also installed 2 IDE data drives connected to a Highpoint raid
controller in a mirrored configuration. These drives have existing data
on that I want to keep.  

Does anybody have experience or know how to get the mirrored drives to
appear as 1 rather than 2 so that I cant read or write from either.  

Thanks JAMES
