Cluster Creation Issues

Hi,

I am new to clusters and have been mainly following instructions on how to create them using step-by-step guides. I have cleared up 90% of all issues in the validate a cluster configuration report however I just cant get rid of these 3 issues:

"none node1.xxx.com and node2.xxx.com are connected by one or more communication paths that use disabled networks. these paths will not be used for cluster communication and will be ignored. This is because interfaces on these networks are connected to an iSCSI target. Consider adding additional networks to the cluster, or change the role of one or more cluster networks after the cluster has been created to ensure redundancy of cluster communication"

and...

"The communication path between network interface node1.xxx.com - Private and network interface node2.xxx.com - Private is on a disabled network."

and...

"Node yyy.xxx.com is reachable from xxx.xxx.com by only one pair of private network interfaces. It is possible that this network path is a single point of failure for communication within the cluster. Please verify that the single path is highly available, or consider adding additional networks to the cluster"

Notes to consider:
Both servers are running windows server 2012 R2.
Both servers have only two nics (I know not recommended)
NIC 1 IP is on the 192.168.168.x  netmask is 255.255.255.0 (Correct)? Management
NIC 2 IP is on the 192.168.169.x  netmask is 255.255.255.0 (Correct)? Cluster Comm.

All other tests have passed and the storage is accessible by both machines and the iSCSI storage network is on the 192.168.169.x network

Can someone help, I've looked everywhere?

Thanks people!

Check you NIC Adapter settings along with proper IP addresses (Disable Ipv6 if it ticket), Disable firewall and try to ping both the nodes each other with NIC1, NIC2 and check for the connectivity.

Also refer http://blogs.technet.com/b/askcore/archive/2010/02/12/windows-server-2008-failover-clusters-networking-part-1.aspx for network settings in fail-over cluster.

Also Try to keep management and cluster comm on NIC1 and keep Storage network on NIC2 (Just a Guess looking at the error.)

I ignored the error and continued with the setup and it worked fine.
I think it was just complaining that there isn't a third network adapter.
all working fine now!
