Hello all.,
I had change in IP address on my CUCM Cluster, which has a Publisher and one Subscriber.
I followed changing IP address procedures as below-
1)Changed SUB IP Adds from CM PUB Admin Page.
2)Changed the Gateway and IP from SUB CLI. Restarted.
3) Changed PUB IP from SUB -OS Admin and then again Restarted.
4) Changed PUB Ip from Pub Admin page
5)Changed PUB GW and IP from PUB CLI and restarted the Box.
Now when i check the DB Replication- i could see PUB Status: 2- Good
But Sub Its shows N/A.
Iam able to access both servers from GUI, and CM and TFTP,DB Repl. Services are up in both servers.
I restarted the servers couple of times..
Any clue why Subscriber shows N/A in replictaion status.
Thanks
Bobby

Hi Bobby,
Absolutely.. you need to setup your forward and reverse lookups on your DNS server
Once that is done, you need to test with ssh on the pub
run the foll
utils network host
once that is in place perform
utils dbreplication stop on sub
utils dbreplication stop on pub
utils dbreplication reset all from pub.
Hope tis helps

Hi Bobby,
Have you tried to do the following?
1. utils dbreplication stop - on all nodes, first on the SUB, then the PUB
2. utils dbreplication reset all - on PUB
NOTE: It is recommended to run this procedure during off-peak hours, because can increase CPU usage.
Regards,
Tere.

Well, it should work even without DNS as it uses local host files. For me typcially the ultimate solution is this procedure, just did it the other day for same scenario you are describing where servers were not in DNS either:

Just to add here, you need to be patient as well as this may take some time.

Well there is a reason ,when you populate dns your .rhosts files are setup with fqdn not the hostname, now when dbrepln setup request comes in it will look.for the entry of.the .rhosts and then resolve it.locally which wouldn't work and when it looks at external resolution if yoy dont have dns correctly it would fail therwby breaking dbrepln.
