Ryan -
What you say is interesting because it contradicts what the guy on my
license TAC case specifically told me (I can provide you his name in a private
email if you wish)
"Note that the licensing is tied to the eth0 mac address so if your
ELM is a VM be sure it has a static mac address."
I specifically asked him this question and was told that
starting with 9, the licensing was no longer tied to a MAC but only to a random
set of characters generated by the ELM when you do the license request.
That will be important to know which is true so that I can tell
the client the correct information.
It seems as if the dedicated ELM is the correct way to go - but
Im not sure if the client wants to dedicate the HW/VM to building one. They
are constantly changing the architecture (it's a true lab)

I agree with Matthew, if you are spinning up lab clusters or moving things
around go with a dedicated ELM/PLM. Note that the licensing is tied to the
eth0 mac address so if your ELM is a VM be sure it has a static mac address.
There are no node licenses, so you can add multiple cluster to the same ELM and
they will only consume licenses based on the number of configured users and
devices.
You don't want to be rebuilding or migrating the ELM anywhere. If you don't
have to do that then there will never be a need to rehost a license going
forward.

Subs don't talk to ELM. Only the Pub talks.
You then have two possible setups, dedicated ELM/PLM and Colocated ELM/PLM with
CUCM or Unity Connection.
You also have one other scenario, rebuilding the Pub that you've mentioned.
If you have the VM Resources considering all the changes you are talking about
I suggest a dedicated ELM/PLM server. You can use the smallest sized CUCM OVA
for this.
The following possibilities exist with moving/rebuilding:
Rebuild collocated ELM/PLM and CUCM - You will have to rehost your ELM/PLM with
TAC, you will also have to add the new Pub to ELM/PLM.
Rebuild Dedicated Pub when having dedicated ELM/PLM. Just add the new Pub to
ELM/PLM and delete. TAC not involved.
Rebuild ELM/PLM Dedicated Instance - You will have to rehost your ELM/PLM with
TAC, you will also have to add the existing Pub to ELM/PLM
Migration of any servers -Migrating a shutdown instance of a VM using the
Migrate function should cause no licensing changes as all hardware properties
are kept the same.
If you do a copy of the VM via VMWare that is not the case some hardware
properties can change and this may cause ELM/PLM to need a rehost. A manual
copy may work. I haven't tried it.
I think I've addressed all of your scenarios, let me know if you need
clarification.

Subject: [cisco-voip] Impact upon licensing in lab environment
Greetings all -
My client recently purchased 2 x PAKs for CUCM servers. They have
several physical host machines configured with ESX5.
My understanding of the difference with CUCM 9 is the ELM. Licenses
are no longer tied to the MAC but are tied to some random characters generated
by the ELM during the license file upload process.
This is a lab environment so I want to be sure that I am advising them
correctly on the impacts of the following actions:
Assuming that both PAKs are registered to the single ELM (currently
they have a Pub and Sub - each of them running inside ESX 5 on the separate
physical host machines)
1 - what would be the impact if the SUB VM were physically migrated
(via copying and moving ova file) to the physical machine hosting the Pub? My
gut tells me no impact
2 - what would be the impact if the CUCM pub and ELM (co-existing on
the Pub) were physically moved (via copying and moving ova file) to the
physical machine hosting the Sub? My gut tells me no impact.
3 - what would be the impact if the Sub were decommissioned and
rebuilt as a Pub in a new cluster? My gut tells me that it would take TAC
involvement to rehost the license
4 - what would be the impact if the Pub were decommissioned and
rebuilt as a Pub in a new lab configuration? My gut tells me that it would
also take TAC involvement to rehost the license
