ESXi hardware sensor false alerts

Have noticed when working with HPE Gen10 ProLiant servers with ESXi they can produce false hardware sensor alerts in vCenter 6.7 and 7.0

  • If it has been confirmed that the alerts are not genuine, they can be set to an ignored state in the IPMI hardware monitor
  • Note: the sensor numbers will in some case reference more than one sensor – i.e. Setting a falsely alerting sensor to ignored may mask another valid sensor reading
  • Find the Sensor number:
esxcli hardware ipmi sdr list
0.2          Memory Device 2 Mem_Stat_C01S03            32.2             Configuration Error  sensor-discrete      192          Memory            2020-10-29T14:13:17
  • The number needed is the non-zero integer in the first column – e.g. 2, in the above example
  • Set those sensor numbers as ignored:
esxcfg-advcfg -s 2 /UserVars/HardwareHealthIgnoredSensors
  • Confirm:
esxcfg-advcfg -g /UserVars/HardwareHealthIgnoredSensors
  • Clear any existing alerts, Reset the Sensor Event Log and restart the CIM service through vCenter
