Our AS400 (9406-250 V5R1) has notified us that its 2763 i/o adapter card (raid controller) has failed and should be replaced and also mentions replacing the cache battery pack. I can buy refurbished parts that match the IBM part numbers, but my question is... is it simply a matter of locating and replacing the parts then restarting the system. Or must there also be configuration work included? The disk drives are fine and we intend no change to the current config but I have never configured a raid controller manually. Will this be necessary?
