PHM checks for HSM generated hardware failure events every 10 minutes.

You can customize the time interval using the vSAN configuration file.


  1. Log in to vCenter Server console as root.
  2. Open the /usr/lib/vsan-health/VsanVcMgmtConfig.xml file.
  3. Set the interval value using healthUpdatePollIntervalInSeconds xml tag.
  4. Restart the vSAN Health service.


PHM uses these events to generate alarms, which appears in the vSAN Skyline Health. For more information on the vSAN Skyline Health events, see the VMware knowledge base article at
