The output includes the vSAN node UUID, IPv4 address, IPv6 address, UDP port with which vSAN node communicates, and whether the node is a data host (0) or a witness host (1). You can use this output to identify the vSAN cluster nodes that are operating in unicast mode and view the other hosts in the cluster. vCenter Server maintains the output list.
