setting up dmraid events

I'm really new to dmraid, so this should be an easy question for someone to answer :)

I've got dmraid set up on my machine (ICH10R controller), and I've been told that if I want to see when the RAID state changes (i.e when I pull out a member disk, then the metadata should be updated to indicate that a specific disk has been removed), then I should install the "dmraid-events" package. I did a search for this package, and I don't see any packages that have this name...I doubt this, but: does this package go by another name?
