After you create a cluster, Host Monitoring enables the vSphere HA master host to respond to host or virtual machine failures and management network isolation. The VM restart priority and host isolation response determine how vSphere HA responds to host failures and isolations.
The Host Monitoring page appears only if you enabled vSphere HA.
- In the vSphere Web Client, browse to the vSphere HA cluster.
- Click the Manage tab and click Settings.
- Under Settings, select vSphere HA and click Edit.
- Expand Host Monitoring to display the configuration options for host monitoring.
- Select Host Monitoring to enable this feature.
- Select the VM restart priority for virtual machines in the cluster.
The restart priority determines the order in which virtual machines are restarted when the host fails. Higher priority virtual machines are started first. This priority applies only on a per-host basis. If multiple hosts fail, all virtual machines are migrated from the first host in order of priority, then all virtual machines from the second host in order of priority, and so on.
- Select the Host isolation response.
The host isolation response determines what happens when a host in a vSphere HA cluster loses its console network connection but continues running.
- Click OK.
Host monitoring is enabled and your virtual machine restart priority and host isolation response settings take effect.
