EMC Data Domain comes with Raid 6, and 1 hot spare. I'd like to convert that hot spare to active and get that space.  Anyone know how to do that?

    You can't, I'm afraid. Data Domain boxes have a specific RAID 6 stripe size (which is determined by the number of drives in the RAID 6 set) , and optimises disk performance by writing and reading data optimised to that stripe size. It's one of the reasons why they are so fast. If you were able to add the disk to a RAID 6 set, you'd break the performance.
