Windows Server 2012 Fail over Cluster Installation Issue.

Hi All,

I am deploying the new Failover cluster on Windows Server 2012 OS on UCS blades environment. While validating the cluster configuration i am getting the below error , Can any one please suggest the solution for the below issue.

Validate Network Communication

Description: Validate that servers can communicate, with acceptable latency, on all networks.

Analyzing connectivity results.

Node cluwin1.is.world.com is reachable from node cluwin2.is.world.com 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 cluwin1.is.world.com to network interfaces on node cluwin2.is.world.com

Thanks,
Madan.

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.
