Analyzing connectivity results.

Node is reachable from node by multiple communication paths, but one or more of these paths experienced more than 10% packet loss.

Following are the connectivity checks made using UDP on port 3343 from network interfaces on node to network interfaces on node

Straightforward networking error there. The detailed report should say which interfaces are not communicating 100% of the time. Keep in mind that for proper clustering, you want a separate network for cluster traffic, and ideally even break that out for heartbeat, CSV, etc so you don't have false failovers from a congested network. That means multiple adapters per blade, each on their own subnet, and configured to handle that traffic.
