SOLVED Supermicro IPMI reachable but almost nothing works after BMC Firmware Upgrade

EDIT:
I left the Mobo Battery out overnight and the issue fixed itself.
I had left it out for around and hour before, I guess that wasn’t long enough to reset whatever needed a reset.

Hey Forum,

earlier today I attempted to upgrade a BMCs Firmware Version through the IPMI Webinterface but ended up with a major issue.

The Board in question is a Supermicro X10SRi-F.

Everything went as usual but after the Webinterface reloads all the fields for information (IP Address, Hardware Details) are empty and almost all settings don’t work.

The Webinterface is at the set IP Address and I can power on / off / restart the machine, but KVM isn’t functional and almost all settings don’t do anything when pressed or options show “undefined”.

What I’ve tried so far to mitigate the problem:

  • Reset all Configuration to default with ipmitool (Webinterface Setting doesn’t do anything when clicked)
  • Also upgraded the BIOS to the latest version
  • Manually reflashed the BMC Firmware using Supermicro’s supplied flashing tool from a Live USB

One interesting thing I noted that at least some things work when I check with ipmitool from the Shell, I can read out sensors and see the Event Log as well as issue certain commands. All of that is not available in the Webinterface.

I hope someone here has an idea I didn’t try yet or is more experienced troubleshooting Supermicro’s IPMI.

In case it’s helpful: I’ve got an identical Board and CPU that’s still on the older version which might come in handy during troubleshooting.

Do you have the ability to downgrade the firmware?

I could dump the BMC Firmware from the other Board I have and flash that to this one.
But I haven’t been able to find anything conclusive on whether that’ll work as I imagine it to.

They wouldn’t have introduced a browser incompatibility problem? Like, you have tried other browsers?

I have tried that.

But I believe the issue is deeper than my Browser, because I can log into the Webinterface and use a few options (like remote power on/off), while most settings and readouts like sensors don’t do anything when clicked and some even just say “undefined.”

And I’ve got a third Board from Supermicro which is different but has the same BMC - that one works fine after the same FW Upgrade Process.
Now I’m a bit stuck because I don’t want to upgrade the second, exact same, Board before I find the problem.
