CUCM8.6.2, Rebuild Pub-Node Fail...

Hello,

I follow the link to rebuild my pub-cucm.

https://www.cisco.com/c/en/us/support/docs/unified-communications/unified-communications-manager-callmanager/116946-technote-product-00.html#anc3

-----

step1. utils dbreplication stop >> To stop DB sync (Sub)

step2. reintall pub-node, and config cucm server list.

step3. restart pub-node....

-----

When I restart the new pub-node... I find all sub-node still sync DB data from pub-node! So, All config is cleaned... Orz...

I already enter the dbreplication stop command on all sub-node.  Why not work ?

Have any wrong during my process.

 

This is the log from sub-node to stop dbreplication:

===========

admin:utils dbreplication stop
********************************************************************************************
This command will delete the marker file(s) so that automatic replication setup is stopped
It will also stop any replication setup currently executing

Please run the command 'utils dbreplication runtimestate' and make sure all nodes are
RPC reachable before a replication reset is executed

TVSC1CCM03 10.208.2.13 0.039 Yes Connected 0 match Yes (3)
=========
Is there any wrong step?

 

Thanks~

Just saw your post, why do you think the DB is wiped out, can you shutdown the pub and check again. After the Pub comes up and authenticates and when you put in the Sub's ip address/hostname on a browser you no longer see the Sub's DB, you will only see the DB of the Pub which would be empty even though the Sub's DB entries are intact. If you want to access the Sub's DB then shut down the Pub or run a sql query for fetching information on the Sub's CLI.

Please rate if you find this helpful.

Can you go to serviceability and make sure that you stop DB replication.

Hello,

 

I do it successfully...

On CUCM8.6 Lab:

1. Stop dbreplication at all sub-node.

2. When the new pub-node add all cluster server, then all sub-node's phone information & all config be cleaned, like as the new pub-node....

3. But don't care it, just to do backup & restore by DRS.

4. When restore from sub DB finish and success, the DB will be OK~ It restore data from original sub-node!

 

So, the process cannot run at production environment, downtime about 30mins.
