We are currently running CallManager version 7.0.2 with one publisher and two subscribers. Trying to add another subscriber. The server and software has been installed, we can see it in CallManager System --> Server and System --> Cisco Unified CM.but have not yet added the new server to any Cisco Unified CM Group. When we look at the Database Summary the replication status all nodes show a status of 2 except for the new server which shows a status of 4.
Do we just need to add the new server to our Cisco Unified CM Group?
If we add the new server to our Cisco Unified CM Group and there is an issue with the new server, will it "hurt" anything?
Can we just delete it if there is an issue?
That means replication is not working, you need to fix that in first place. There are plenty of threads on the topic if you need instructions.
Yes, if you add a server that is not pulling the same DB as the PUB you can have issues.
Simplest way to check the health of the cluster is to go to the CUCM webportal>CUCM reporting.
and go to Unified CM Data Base status. it gives you the replication status of each member.
DB replication issues are notoriously hard to fix though, you might want to consider raising the issue with TAC if you are not confident enough.
from CLI of PUB, u can run the command show network cluster and show tech network hosts.
In addition to what Dear friends have said, please check u have Node License avaialble for new SUB
Depending of CallManager version can be license issue
Also please try to configure subscriber as IP address not as "name"
Then try "utils dbreplication reset all" on publisher and restart publisher
