When a datastore enters a Permanent Device Loss (PDL) state, High Availability (HA) can power off virtual machines located on the datastore and then restart them on an available datastore. VMware offers advanced options to regulate the power off and restart operations for virtual machines.

Advanced Parameters to Regulate PDL




When set to true, this option enables default power off for all virtual machines on the ESXi host.


Power off parameter that you can set for each individual virtual machine.

This option overrides disk.terminateVMOnPDLDefault.


This option is set to true by default. It allows HA to restart virtual machines that were powered off while the PDL condition was in progress. When this option is set to true, HA restarts all virtual machines, including those that were intentionally powered off buy a user.
