When you create a vSphere HA cluster or configure an existing cluster, you must configure settings that determine how the feature works.
In the vSphere Client, you can configure the following vSphere HA settings:
- Host Monitoring
Enable host monitoring to allow hosts in the cluster to exchange network heartbeats and to allow vSphere HA to take action when it detects failures.
Note: Host Monitoring is required for the vSphere Fault Tolerance recovery process to work properly.
- Admission Control
- Enable or disable admission control for the vSphere HA cluster and choose a policy for how it is enforced.
- Virtual Machine Options
- Set the VM restart priority and host isolation response.
- VM Monitoring
- Enable VM Monitoring or VM and Application Monitoring.
- Datastore Heartbeating
- Specify preferences for the datastores that vSphere HA uses for datastore heartbeating.
