c Select Turn ON vSphere HA.
d Select Turn ON Proactive HA to allow proactive migrations of VMs from hosts on which a
provider has notied a health degradation.
6 Under Failures and Responses select Enable Host Monitoring
With Host Monitoring enabled, hosts in the cluster can exchange network heartbeats and vSphere HA
can take action when it detects failures. Host Monitoring is required for the vSphere Fault Tolerance
recovery process to work properly.
7 Select a seing for VM Monitoring.
Select VM Monitoring Only to restart individual virtual machines if their heartbeats are not received
within a set time. You can also select VM and Application Monitoring to enable application
monitoring.
8 Click OK.
You have a vSphere HA cluster, populated with hosts.

Configuring vSphere Availability Settings
When you create a vSphere HA cluster or congure an existing cluster, you must congure seings that
determine how the feature works.
In the vSphere Web Client, you can congure following the vSphere HA seings:
Failures and responses
Provide seings here for host failure responses, host isolation, VM
monitoring, and VM Component Protection.
Proactive HA failures
and responses
Provide seings for how Proactive HA responds when a provider has
notied its health degradation to vCenter, indicating a partial failure of that
host.
Admission Control
Enable or disable admission control for the vSphere HA cluster and choose a
policy for how it is enforced.
Heartbeat Datastores
Specify preferences for the datastores that vSphere HA uses for datastore
heartbeating.
Advanced Options
Customize vSphere HA behavior by seing advanced options.
