An administrator attempts to configure Host Partial Fail Response, but the automated option is faded. What can the administrator change to enable the Automated option?

Partially Automated DRS only allows DRS to recommend VM placement at power-on but does not grant HA the authority to automatically migrate VMs during a host partial failure event.

Enabling HA Host Monitoring controls whether vSphere HA monitors hosts for failures at all, but it does not unlock the Automated option within the Host Partial Fail Response configuration.

The vSphere HA Automated response for Host Partial Fail Response depends on vSphere DRS being configured as Fully Automated, because the automated remediation requires live-migrating VMs off the degraded host via vMotion under DRS control. If DRS is set to Partially Automated or Manual, vSphere HA does not have the authority to trigger automated VM migrations, which is why the option appears grayed out. Setting DRS to Fully Automated delegates migration decisions entirely to the vSphere engine, enabling HA to invoke DRS-driven evacuations as part of the failure response workflow.

DPM (Distributed Power Management) governs host power state optimization for energy efficiency and is entirely unrelated to enabling the Automated option in HA Host Partial Fail Response settings.
