I encountered an issue testing a DMA migration from Call Manager 4.1.3 to CUCM 6.1.3bSU1. In this upgrade the first node is loaded using a 6.1.3b DVD image and a mid-install patch (SU1) is applied. During the installation of 6.1.3, the host name and IP address are specified with different values than used by the 4.1.3 publisher.
Installation completed successfully and license files could be installed/uploaded without issue. When attempting to load services however the following errors were seen:
>show network cluster
When ran on the 6.1 publisher, the output of this command showed the “old” hostname and “new” IP address. Further, the “old” publisher is listed as a subscriber.
>show tech network host
You will see the “old” publisher name in the hosts file but the “new” publisher name is not
>From the platform web interface show>system has the correct hostname information
>From the Unified Reporting portal, the Database Replication status reports shows various errors related to invalid host names
In addition to the above symptoms, any attempt to start the TFTP service fails. The Call Manager, IP Voice Media Streaming, CTI Manager, and other application services will start but will immediately crash.
Clearly something is amiss with the installation wizard. In other versions, it is noted that the install wizard will actually confirm with the installer that they intend to change the IP address/host name. To resolve this issue, use the following command from the console:
>set network hostname <newpublisherhostname>
After issuing this command, reset the publisher node.
Status for Other Versions.
5.1 : Issue not seen
6.1: Issue found.
7.x: Issue not seen
Recently I tested this with CUCM 7.1(2) and I did not have the same issue. I tested with CUCM 6.1(3) on multiple occassions and experienced the issue.
