Cisco UCM 6.0 Clustering question

[fgasimzade]

Hello, gents!

I have deployed a new CUCM 6.0 server, added it to existing CUCM cluster, everything was fine, replication etc. The problem is that I can not get the phones to register on the server. I have configured a new call manager group with the new server on top of the list, configured new device pool with this call manager group, added ip phone to this device group, but it keeps registering with the publisher.

One thing I noticed, in IP phone menu in Call Manager configuration there is a small lock icon on top of every call manager except the new one. I think i has something to do with phone registration.

Thank you in advance!

One more thing I forgot to mention, when I go to System - Cisco Unified CM on Publisher, there is  a list of call managers configured. When I click on every old server, there is a number of devices used by each server (1142). The new server says it is used only by 1 device.

Adding a new server to the cluster requires to restart all the servers of the cluster.

Did you restart the whole cluster ?

By the way, do you have the proper license for the added server ?

Under the license menu, check the number of node. One call processing server = 1 node.

[fgasimzade]

Yes, license are ok

Are you sure I need to restart all the servers in the cluster?

One more thing, when I go to OS Administration on the new server, Certificate Management, there is no option there to download CTL file. However, on other servers in the cluster this feature exists.

According to the documentation, you don't need to restart the whole cluster.

It seems also that the cluster is in running in mixed mode (CTL).

Sorry but I don't have more idea.
