[Yaniv Malachi]

Hi

I have a customer with cluster of cucm 11.5.1su2 and a a unity connection 11.5.2su2 ,

in the cucm everything is fine but in the unity if u type the command

"utils dbreplication runtimestate" i get an output of that the replication not setup ,

I have check the system and all networking is fine , the server are fine ,

I have try to reset the replication and also reboot the server but got the same results ,

Any ideas what can be the problem ?

How many servers do you have in the cluster ?
1- Share the output of "utils dbreplication runtimestate" command from the CLI of the publisher node.
2- Check the services by running the command "utils service list"
3- Run the command and get the output of "utils diagnose test" and see if it fails at any point
4- Run a test for other nodes using "utils network connectivity" on all the nodes
5- Generate the "Unified Database Report" from Unified Reporting.
Check the syscdr status for all the node in the report. This must show the node entries for all the nodes in the cluster.
6- Check if there is any firewall in betwwen the nodes.
7- You can also check if some ports are blocked by running the command "utils firewall list"
8- Try to ping the nodes and see if they are reachable ot not
9- Check if the DNS resolves the hostname if being used.

PS :- If issue is still not resolved, will suggest you to open a TAC case, as there might be a need of getting the root access which only TAC can generate and do the mendatory changes.

Can you get the output of show network eth0 detail ? And also try to get this below fixed
test - validate_network : Default gateway failed

Try initiating the DB replication after that and see if it comes up or not. Run the command utils dbreplication reset all

Hi Yaniv,

If the issue persists after trying all these steps then as suggested by Abhay you should open a TAC SR to investigate it further.

Hi Manish & Abhay

i have open a TAC case and we have found that there are a

ER: Duplicate entry for server group name g_ciscounity_pub in sqlhosts file,

according the command " file view activelog cm/log/informix/ccm.log .

so the TAC enginner login to the server via root acees , delete the duplicae entry , then

we follow the url insruction to rebuild the cluster , and still have an error of Split Brain Resolution  

at the CUC sub , so we

 Shutdown subscriber server

Restart publisher and wait until all services will start

  Start Subscriber and wait until the services will start

and after that the replication start to work fine ,

i want to thanks you for the hep that u gave to me
