Hello 

do you have the serial cable to know more about this error?

Probably an issue with Storage controllers. Did you try to change batteries?

Sorry I see that you already replaced battery.

This issue comes with new batteries? And if you put the old ones?

image press the C key to continue

i have a serial cable and i access it and i have to press C to continue and when i press c the device is working fine but when i turn it off and on again the error appears again and i have also replaced the old battery but still not Feasibility

Hi, also please review recovery guru for errors and alerts. Might be it can suggest something. 

The Recovery Guru is a component of MD Storage Manager that diagnoses critical events on the storage array and recommends step-bystep recovery procedures for problem resolution.
In the AMW, to display the Recovery Guru, perform one of these actions:
• Select Monitor > Health > View Health (Recovery Guru).
• On the Summary tab, click the Storage Array Needs Attention link.
You can detect a problem using the following indicators:
• Non-Optimal status icons
• Alert notification messages that are sent to the appropriate destinations
• Hardware indicator lights
The status icons return to Optimal status as problems are resolved.

it could be fixed remotely, whether dell would do that i dont know.

it hangs at that step so it can't connect to MD Storage Manager only when pressing C the device can access and then it's optimal but when shutting down and turning on again it hangs at that step .image below is when I press C continues

Hi, the only thing that came to my mind run the command lemClearLockdown but you mentioned already did it. Feeling a little stuck here, let's see if the community will recommended anything.

Thank you for your help, hope someone can help me

I have exactly the same issue. I had to replace mSATA in the controller, did it correctly and the sytem came back healthy, but then I replaced the RTC battery and the fat LFP backup battery too, thinking that I would give the controller a little more juice for staying normal for longer time. Shoot --- a very bad decision. The system hangs during bootup, complaining that RTC battery is low. I always have to press C(ontinue) on the console every time it reboots. Just out of curiosity, I opened up the other perfectly working controller and took out the RCT battery and then replugged it in in its place, and voila!, it also hangs during bootup with the same complaint. Maybe the RTC battery in an MD3820f controller should never be taken out. (If it was designed that way, Dell should have soldered it or put a warning or something!!!)

Does anyone happen to know how this situation (Getting RTC battery low warning even though battery is OK) can be fixed?

Thank you very much all!
