iLO 4 shows "unknown" for some fields on the overview page

[NJK-Work]

Something happened to a few iLO4 devices (not sure exactly what yet) that caused them to lose all settings (except NIC was still correct, so I could connect remotely) and then on the overview page after login, I see a bunch of unknowns for various details.  I have attached a screen shot.  The server is no unable to be managed in HP SIM as well via AMS.  I believe the fans are also running at full speed now...as if power management is broken.

I have tried updating the firmware and restarting the iLO several times.  The only thing I have not done is pull the power on the server to cold boot it.  Has anyone else seen this?  Will cold-booting fix this?  Or is there a less extreme action one can take to fix this.  Trying to avoid outage to the server....

Thanks

a reboot may help, pulling the power plugs definetely helps.

ILO version 2.54 should prevent this behaviour.

Pulling the power on the server, thereby cold-booting the iLO, fixed the problem on the first server.  Assuming will work on the other two.
