Error while restoring CUCM, CUC or UCCX

Error while restoring CUCM, CUC or UCCX

Have you ever face an issue “ERROR: At least one of the servers which was requested to be restored is not connected: CCX-PUB. This may be due to Master or Local Agent being down., Restore Completed...” while restoring the backup on UCCX? Similar issue can be faced with CUCM and CUC as well.

I faced the same issue in my lab. I did checked the DRF Service Master and Local which was running as expected. I did restarted the services as well but no luck. I did verified the Database Replication between the two servers which was Good. I also tried accessing CCX-Pub and CCX-Sub from CCX-Pub Serviceability Page (Network Services) which was accessed without any issues. I also verified that license has been installed (Premium Demo License).

After few hours of troubleshooting, i realized that the Hostname in my CCX-Pub is not matching with the last working CCX-Pub for which the backup was taken. The hostname were different on the newly installed CCX-Pub and Last working CCX-Pub. And with UCCX 8.5x, you cannot change Hostname once the Publisher/Subscriber is Installed. So, i ended up in rebuilding CCX-Pub and CCX-Sub.
I would say it is always better to verify the below parameters.

  • Hostname
  • IP Address
  • Subnet Mask
  • Gateway
  • Software Version of Source Cluster (Backup Taken) and Target Cluster (Restoring Cluster)

Hope this helps!!
