This article provides information on how to troubleshoot PowerEdge RAID Controller (PERC) battery errors on a Dell PowerEdge Server
Issue 1:
Memory Or Battery Problem Error Message
Memory/Battery problems were detected. The adapter has recovered, but cached data was lost.
Press any key to continue
Probable Cause:
The adapter detects data in the controller cache that has not yet been written to the disk subsystem. The controller detects an Error-Correcting Code (ECC) error while performing its cache checking routine during initialization. The controller discards the cache rather than sending it to the disk subsystem because the data integrity cannot be guaranteed.
The battery may be under charged.
Corrective Action:
Allow the battery to charge fully to resolve this problem. If the problem persists, the battery or adapter DIMM might be faulty. Contact Dell Technical Support.
