I'm trying to replicate second node with first node in HA Configuration ,,But it says Add to Cluster is failed because of Connection time out. Please try again with correct entries. but both IP's are reachable over LAN and updated second node details in the first node as well.
I appreciate if you can one let me know what could be the reason ?
Solved! Go to Solution.
Hi Suryanarayana Chintu,
Could you please check the below few points.
1. HA license is present in the First node of UCCX before performing the Add to cluster operation.
2. Same type of hardwares (MCS\UCS\OVA template) are being used in both the nodes.
3. DNS resolutions are proper.
Hope it helps.
Please rate helpful posts !!
Thank you so much for your reply, As you mentioned 1 & 2 points are fine. But can you please little elaborate as I have'nt had any DNS Clinet configuration on both nodes.

Hi Suryanarayana Chintu,
UCCX node's hostnames should have an entry in the DNS server, and as part of the install you will see a mandatory stpe to enter the primary DNS server.
Thanks for your reply , Probably this might be the issue since I havn't given DNS Server details on both nodes.
Actully , I have DNS Server in the Lab , Shall I update this DNS Server IP details on both nodes? Please advise.
Hello Anand , Thanks for your reply .
I'm trying to set DNS primary address via CLI , There was a warning : Changing this setting will invalidate software license on this server . The license will have to be re-hosted. So , I should upload license again right ?
If I upload license file again , what are the other changes will effect? Please advise.
If you have no DNS it shouldn't have caused communication issues between both boxes.
- Have you added the secondary node onto UCCX Node 1
That sounds more likely the issue as you have no DNS thus far and sounds like CSA hasn't allowed communication from your secondary node.
Note: UCCX 9X forces customers to use DNS now, an option you cannot skip.
Thanks for your reply,
I haven't updated DNS details on both nodes yet, As you mentioned how can I check CSA status on secondary node.
Note :This is for your information I have installed both nodes are on different VMs,
What I meant was on UCCX Node 1 appadmin page, System>Server
Add in secondary server IP address.
Try that first before you start making DNS changes.
I have updated DNS details on both the nodes and trying replicate but again the same error: Add to Cluster is failed because of connection time out, Please try again with correct entries. Also I just checked second node status in the first node which shows UNKNOWN. Please advise what could be the issue?
Looks like some network connectivity issue.
Please make sure that both the nodes are accessible to each other by ip address\hostnames and also make sure that the CUCM and DNS servers are all accessible.
Run the following from node 1.
utils network ping "node2ip"
See if they are reachable between the different vm host as all the other possible causes have already been addressed.
If it is reachable, then try disabling the csa on node 1.
I tried to ping second node IP/hostname from first node both are reachable and response also good.
CUCM , DNSs are also accesible. Can you please let me know how to disable CSA on node 1.
Are you using the same Version\Build\SU on the second UCCX node as of First UCCX node?
Is your hardware\OVA template are same on both the nodes?
HA license is applied on Publisher? Second Node details are added in the First node?
If all these things are valid, than you need to check the logs for the exact reason for failure.
