Cannot Ping nodes in Smart Connect Zone

[Anubhav]

I am seeing an issue with the smart connect zone. I have got two smartconnect zones with 4 nodes. I am able to do a nslookup and everytime i get a different IP address based on round robin policy, but when i ping the smartconnect zone name i am getting connect timed out. though everytime i ping i get a different IP but the connection is timing out each time. What can be the issue?

The fact that you are getting a different ip address each time  means that your DNS server can reach the SmartConnect service ip and that SmartConnect is working as you intended. It also means that your client is correctly configured to connect to your DNS server. It does not mean that your client can talk to the Isilon cluster. 

The problem sounds like it could be that your client is not configured correctly to reach the Isilon cluster. Perhaps you should take a look at your routing configuration. Have you tried traceroute to your cluster?

Have you tried pinging from one node of your cluster to the external ip address of another node? This would confirm that the cluster is working correctly.

I am just pinging from my desktop (windows machine) which is in the same network as the clusters. There are two other smart connect zones, which i can get to, but not the new ones i created.

I tried pinging the IP addresses of the nodes in the smart connect zone from other nodes and same issue "Request timed out". I tried changing the IP address to something different, but the issue remains the same.

It sounds like you have a misconfigured SmartConnect zone; you should be able to ping the SmartConnect zone name. If you run "isi_for_array -s ifconfig", do you see the floating SmartConnect IPs on any nodes? Are they in the same subnet as the working SmartConnect zones? Does "isi_for_array -s netstat -rn" show correct routing configuration on all nodes?
