FAS2020 - failing controller?

UNDECIDED — Thu, 05 Jun 2025 06:28:16 GMT

We have a FAS2020 that have a failing controller.

After replacing the faulty controller with a new one (all done by the manual) we got the following error:

Waiting for nvram battery chargeupPress Ctrl-C for Maintenance menu to release disks.

Waiting for nvram battery chargeup

Due to the above error the controller wouldn’t boot.

We replaced the battery with a new one and got the following error:

We also tried the following: Reseat the battery, then let the system stand in LOADER prompt for a couple of hours to see if it will recharge (recommended by NetApp)

Same problem:

Waiting for nvram battery chargeup

We got another battery just to make sure that there was nothing wrong with the second one and still the same!!

Then we decided to replace the controller once more!

We replaced it and here are the messages as the node boots up..

Any help much appreciated, we've been struggling with this for some time now!

What did support say? Escalate the case. Not much you can do when Rma gear doesn't work other than escalate. See if fixable or if another Rma is needed. An overcharged battery I haven't seen before.

Not sure about the 2020 but I know on the 3240 when you replace the MB you have to move the old battery to the new MB. You do this before you swap the RAM and little CF card under the blue box.
