AS400 io controller 2763 replacement
Posted on 2010-08-23
We have received an AS400 hardware error src27638008 which tells us to replace our io raid controller 2763. Naturally we are not under a maintenance agreement (that's another story). I can get replacement parts 91H4082 (the controller) and 44L0313 (battery backup), power down and replace these components. My questions is....
This is a raid controller. By powering down and replacing the controller (and battery backup) will I lose any configuration the controller might have stored on it? If not, why the battery backup? If so, how do I avoid losing the controller config and potentially system access to the data on the drives controlled by this controller without going thru a very long restore process?
