Multicast is not enabled on the nodes "{0}"
Cause
The Configuration Verification Utility (CVU) determined that the cluster interconnects on the indicated nodes do not have multicast enabled.
Action
Ensure that multicast is enabled on the cluster interconnect interfaces on all the indicated nodes. Also, ensure that the firewall rules do not affect the cluster interconnect interfaces, protocols or network address space. On the Linux platform, the iptables or firewalld configuration may interfere with the network connections. Check that promiscuous mode is enabled on the DOM0 interfaces.
