Command MegaCli -AdpBbuCmd -aALL return error

Jason_Asia,

What is the controller that is installed on the server, as well as what is the server itself?

I ask as some of our controllers are without batteries as well as it could be that the firmware is really out of date and it is causing other issues. 

Let me know what you find.

Hi,CHRIS H,

The controller is MegaCLI SAS RAID Management Tool  Ver 8.07.07 Dec 19, 2012.

The server is PowerEdge R720.

RAID card version:
Product Name    : PERC H710 Mini
FW Package Build: 21.2.0-0007

Result of "MegaCli -AdpAlILog -aALL" contains :

The information you provided shows the controller is currently on the latest firmware. Also the list you provided aren't errors, they are notifications of the battery telling you it is going to start a learn cycle. What that means is that the battery,  in order to keep the battery conditioned and not getting a memory, will charge fully and then drain. It repeats this to keep the battery healthy for longer. It isn't going to negatively affect the system at all. It is just a preventive maintenance feature. 

Is that all you are seeing reported for the battery?
