It looks like your PERC RAID controller might be telling you there is 
a detected problem with one of the drives (id 2), possibly. I'm not 
sure what a SMART error looks like coming from the aac driver in 
FreeBSD, but that could possibly be it. Usually, the drive in 
question will physically change the status light from solid green to 
a flashing amber or flashing amber and green... I think the later if 
it's a SMART failure. If everything looks ok on the server, someone 
more knowledgeable about the aac driver and PERC controllers would 
have to comment.

Then again I could be misinterpreting it, but seeing as you got no 
other responses it's a place to start looking. Look at the drive in slot 2.
