To configure HA functionality, you must set up a cluster and create a cluster heartbeat device.
A cluster is a component of the server pool and is created by submitting a POST request to the server pool's URI:
https://hostname
:port
/ovm/core/wsapi/rest/ServerPool/id
/Cluster
The cluster heartbeat device is a component of the cluster itself, and is created by submitting a POST request to the cluster's URI:
https://hostname
:port
/ovm/core/wsapi/rest/Cluster/id
/ClusterHeartbeatDevice
