I had this same problem today when I removed two hard drives (to wait until the corrupt. bug is over). However, I resolved the problem when I realized the hard drives are hot swapable. Therefore, when they are removed from the system, do not shut down to remove the drives just remove them and the light should go out.
What I did was put the drives back in upon after it was shut down and then started it up ensured the drives registered and then removed them and everything was fine. (Lights on the light bar went out).
