host* | ManagedObjectReference to a HostSystem | ManagedEntity of witness host.
nodeUuid | xsd:string | vSAN UUID of witness host

unicastAgentAddr* | xsd:string | IP address used by witness host, to communicate with data hosts in vSAN stretched cluster. The IP protocol supports IPv4 and IPv6, and which protocol to take, is determined by concrete vSAN network configurations on all hosts of vSAN stretched cluster. If both protocols are supported by all hosts, IPv4 will be taken. This IP address is from the first discovered virtual adapter of witness host, which enables vSAN traffic and supports taken IP protocol.
