Working with the Proactive Hardware Management function

Introduced in vSphere 8.0u3, Proactive Hardware Management(PHM) is a feature to notify on a failing disk drive prior to vSAN hitting read/write issues, so users would have recommendations from VMware and Lenovo in the event of a disk health issue.

Before you begin

  • Ensure that LXCI is enabled as the hardware support manager for PHM. For more information about enabling PHM, refer to Enabling/disabling Proactive Hardware Management.

  • Ensure that the disk is added to a vSAN disk group. PHM only works for the disks in vSAN disk group.
