Hello all,

First of all, thanks for the help!.

We have a poweredge t420 with a perc h710 and receive a error related to the battery of the perc ("Cache data discarded due to Memory/Battery issue").
I replace it but I still get the error, which makes me think the error may come from an outdated firmware.

Now the question is.. Can we update the firmware from any version?

We have the firmware version :  21.2.0-0007 , and controller version 06.801.52.00

The last on dell : 21.3.4-0001

Best regards!
