Clear error messages

It isn't often this happens, but every so often I run into a really clear error message. All too often it's stuff like "0x80042000" that I then have to google to figure out. So imagine my delight when I ran into this baby the other day:

Hard to be more clear than, "dlu=0DEAD:DEADh".

Fixing it turned out to be remarkably easy. Just pop the battery card off of the controller and reinsert. That seems to have cleared whatever it was that caused this. And off I go. In this case, this server had been powered off for close to 3 months and I'm guessing the RAID battery had simply fully discharged.
