I have configured ICSP with media server.

From oneview REST API reference, there is no link for provison.

Need REST API commands for provisiong ESXI cluster

HPE OneView vSphere Grow Cluster is the feature you are looking for.  It is found in the HPE OneView for vCenter plugin.  Unfortunately, there isn't an API to control that feature in the plugin, as it is used via the vSphere Web Client.
