I just got this message on the front panel of one of our servers, a Dell PowerEdge 2900. I believe this means that the RAID controller card battery is nearly dead. The question that I have is what happens when the battery runs flat? Will the server stop working? Can it cause damage?
Should the server be shut down? need to know as we're nearly at the end of business on a Friday afternoon and it'll be impossible to get a replacement immediately.

You may end up with a singularity forming in your server closet if you don't replace it.
Just kidding.
What happens is the PERC controller will stop caching data and your disk performance may drop. That way if there's a power outage, it should prevent you from losing data (or minimize the chances of losing data.
It shouldn't cause any immediate issues if you have to wait a few days to get the new battery. You turn off the server, replace the battery as per the documentation, and power it back up. The server will run fine until you get it replaced.
