Rebuild not working?

[Kelly Beauchaine]

I just replaced a drive in an ML530 server and the array indicates it is 'Ready to rebuild', but it's not! The drive has no lights on it at all. When I first plugged it in there was a solid green light on it, now nothing. Systems Management Home Page indicates all drives are healthy, but the Smart Array 6400 Controller shows Logical Drive 2 is Yellow and in the state of 'Ready to rebuild'. I don't get it. Did I miss something? Server is otherwise healthy.
Thank you!
