OMSA - Current probes not found

Few days ago received power supply 1 failed message.  Green light on PS was on, removed it, swapped out and error did not go away.  OMSA had red X on Main System Chassis, and red X next to PS1.

Manually stopped and restarted DSM services, now OMSA showed green check next to Main System Chassis, and when clicking Power Management group showed the error "Current probes not found".

Then rebooted server, no change.

Was on OMSA 6.3, so did several updates to OMSA 8.4 - no change.  Windows server 2008.

Any ideas?

Thanks in advance.
