Hello -- a couple years ago, John Frandsen built an Aruba pattern and all the related, necessary components to discover Aruba controllers & AP's. This is not part of the standard discovery patterns that come from SNOW, so use it knowing that its not SNOW-supported, but it does work I've used this multiple times because it worked for my customer's needs. Check out post here which includes update set containing all various components.
Hope this helps a bit??
