CUCM 12.5 with PUB+SUB and add another SUB

[Jose Carlos Silva]

I have a CUCM 12.5 with PUB+SUB coresident and add another SUB on a new server.

Everything if running fine - sets registering and making calls, gateways, et,etc, on second SUB. I would like that, in case of fail of the first server where the PUB+SUB reside and TFTP that the second SUB gave the TFTP service. My issue is that I cant upload files to this SUB when I go to the OS administration and try to Install/Upgrade to install de device packs, background logos, device language, etc. I'm using PCD as the SFTP server deposit and the main server sees all the files but when I do the same on the second SUB he gives an error:

"Connectivity Issue to First Node. Verify that the first node is powered on, the network connection is up and the securityCUCM 12.5, Unified Communications password on this node and the first node are the same. You might be also seeing this message due to the installation of the free common space COP file on the publisher. If the intent was to set the "use publisher setting" to "yes/no" in order to facilitate a cluster wide upgrade, then you may ignore this message. ".

TFTP service is active and running on this second SUB. Is there any step missing ot its not suported and I need to deploy a machine, only, with the TFTP service?

Can you help me or point me to the right direction?

Best Regards,

There is no such thing as "PUB+SUB co-resident". Each node in a CM cluster is a VM, that in itself runs on an ESXi host, that equates to a physical server (if your not adding Cisco UCS hardware into the mix as that can add a virtual layer on-top for the actual servers, but that's somewhat out of topic to your original question, so let's put that to the side). There can be many VMs, and usually are, running on the same ESXi node. Hence the term virtual machine.

Are you now saying that you have 2 nodes? What is your actual issue really? Can you not install COP files and such on the CM node named HLA-Subscriber-02?

[Jose Carlos Silva]

Hi Roger!!

That's correct - two nodes and the issue is on HLA-Subscriber-02 - , the issue is that I cant install on the second TFTP, active on the SUB2, the device packs or languages; when I point to the sftp server, the same that the first TFTP uses and work the second one gives the error "Connectivity Issue to First Node. Verify that the first node is powered on, the network connection is up and the securityCUCM 12.5, Unified Communications password on this node and the first node are the same. You might be also seeing this message due to the installation of the free common space COP file on the publisher. If the intent was to set the "use publisher setting" to "yes/no" in order to facilitate a cluster wide upgrade, then you may ignore this message." and does not present the files to install.

 Hi Jose did you fix the problem, I have a similar one too.

Hi!!

Sorry no one gave me a solution that works.

Maybe is like that but I don't read any limitation on the documetation.

[TONY SMITH]

There's no limitation in the product that would prevent what you're trying to do.  And just off the top of my head I can think of a customer of ours who has Publisher and Subscriber on one VMware host, and a backup Subscriber on a different VMware host on a different site. Although it's probably more common for Publisher, Subscriber and backup Subscriber to all be on different hosts, for best hardware redundancy.

I think a problem is that your installation hasn't really been clearly explained.  You seem to be saying you have three CUCM instances, a Publisher, Subscriber No.1 on one host, and Subscriber No.2 on another host.  Yet your CLI output only shows two, and the comment about Pub and Sub sharing an IP address makes no obvious sense.

Is it possible that in fact you only have two CUCM virtual machines?  One of them is the Publisher but is also a call processing server, and your newly added vm is therefore the only Subscriber.  And HLA-Subscriber-02 is the (only) Subscriber?  That would make sense of the CLI output showing only two nodes.

If you can confirm that then people might be able to help.

[Jose Carlos Silva]

Hi, Tony!!

Yes, I have two CUCM virtual machines; one with publisher and subscriber and the other with the second subscriber.

[TONY SMITH]

OK great.  But let's keep the terminology clear, your VM that is the Publisher is not a Subscriber.  Publisher/Subscriber describe the database relationship between the VMs, one VM cannot be both.  So from what you describe you started with a single server cluster, one VM acting as Publisher but also doing everything else as well, call processing, TFTP, media (if enabled).

And now you are adding the first Subscriber, making it a two node cluster.

[Jose Carlos Silva]

Well, for me the first Vm is the publisher, correct, and also makes the call processing, TFTP and everything else; the second is only one subscriber that I add to the first VM (Publisher).

I see, and think now in the wrong way, the first VM as a Publisher/Subscriber but you are correct is the publisher and that one accepts phone registration, sip trunk and so on, also; when I add the new subscriber on the new VM I balanced the registration of the ip sets and want, also, to make the TFTP active to act as backup in case the first Vm fails.

[Roger Kallberg]

I gave you this response quite some time ago.

“There is no such thing as "PUB+SUB co-resident".”

On the same response I also asked this.

“What is your actual issue really? Can you not install COP files and such on the CM node named HLA-Subscriber-02?”

Please clearly describe your issue and what error message that you get. Screenshots are preferred.

[Jose Carlos Silva]

You right, Roger!!

Thanks for your support.

I just want to install the language files and firmware on the second TFTP that is on the subscriber I just add to the previous solution. I want to have a TFTP backup server to work in case the publisher and first TFTP server is not available. Don't know if its possible but didn't read nothing against that.

When I try to upload a firmware cop file or language I have the error "Connectivity Issue to First Node. Verify that the first node is powered on, the network connection is up and the security..."

[Roger Kallberg]

Have you verified that there is full connectivity between your Publisher and your Subscriber? Are there any restrictions in place in your network between the two? Also have you verified that you have a working database replication between the two?

Stating the obvious thing here, but are you 100% sure that you have the same security password defined on both your nodes? If you are unsure follow this link on how to set the security password. Change or Reset CUCM OS Admin and Security Password 

[Jose Carlos Silva]

Yes, security password is the same.

Database replication is ok.

I have both working with sets registered. They are on the same network, so there is no fw in between.

[Roger Kallberg]

Truly an odd one. I guess that you need TAC help on this. What if you do this?
utils network connectivity <FQDN of the other node>

Hi Roger

Cisco Tac Engineer solved the problem. Dbreplication was fine 2 by 2 but Engineer was building, stopping, reseting... the DB replication and after failing to install/upgrade file in Publisher the message  was pointing to restart Publisher and now the problem is gone.

Thank you
