I am experiencing an issue adding a new CUCM Subscriber to an existing cluster.
The Server names in CUCM are hostname based so for example 'CUCMPublisher'
During the validation stages of the install on the new Subscriber, I get the following error:
'Configuration validation with CUCMPublisher (10.10.10.10) failed. Configured first node CUCMPublisher is not a First Node'
I can confirm the new Subscriber is added to the new Publisher in the correct hostname format.
A and PTR records work for the Publisher and the new Subscriber.
test - ntp_reachability : Passed
test - ntp_clock_drift : Passed
test - ntp_stratum : Passed
Synchronised to NTP server (x.x.x.x) at stratum 4
So, you are referencing both correct hostname and IP address of the publisher along with correct security password? Security password is not necessarily the same as OS and App passwords. Also, did you add this new Sub under "servers" in CUCM?
Correct Chris. We wasn't 100% sure on the Security Password but I tested it using the below method and have come to the conclusion that the password is good as I get this response:
'Second time my old password was CORRECT and got "BAD PASSWORD: based on a dictionary word"'
...that is that I am basing an accurate security password on! CUCM doesn't give me a bad password error either.. so have no reason to believe this is the case.
Log in as platform admin
set password user security
Enter <what you suspect is old password>
Enter "cisco123" as new password
Confirm "cisco123" is new password
When prompted for DRS warning, hit "y"
First time my old password was wrong and got "The old password did not match"
Second time my old password was CORRECT and got "BAD PASSWORD: based on a dictionary word"
I will give that document a read now thank you and get back to you.
SUB is not the fisrt server on the node.
Delete and re-add your SUB ip address on your publisher.
Chris, this 'show network host cucmsub01' command works all OK from the Publisher.
I get a response in External Resolution as per below example:
cucmsub01.lab.com has address 10.10.10.10
The FQDN and IP are correct.
FYI - Local Resolution states 'Nothing Found'
Is Subscriber being installed across WAN ? check for ports [getting blocked] if firewall is installed .
