Updating ESXi hosts to version 6.7 (or specifically 6.7 U1) might lead to warnings appearing in the Hardware Status tab of vSphere Client. These warnings might not be genuine hardware issues.



Possible cause for this issue is that the update might alter how the ESXi host reports hardware health information through SOAP sensors.


Potential Solutions:

  • Verify with hardware vendor: Before proceeding, ensure the warnings don't indicate actual hardware problems. Check with your server manufacturer.
  • Reset event logs: Even if the hardware is healthy, the warnings might persist. Try resetting the event logs within vSphere Client. Steps include resetting the System event log and Hardware Status sensors.
  • Restart Management Agents: Restarting the sfcbd service (ESX) or using the services.sh restart command (ESXi) might help resolve the issue.
  • Firmware Updates: In some cases (like HPE servers with firmware version 1.30), updating the server firmware might address the issue.

Additional Information:

  • There might be a potential fix in ESXi 6.7 U3 (Build 15160138). Updating to this version could resolve the issue for some hardware configurations.
