How can I learn CUCM Publisher MAC Address

[huseyin]

Hi everyone

Our customer lost the CUCM Publisher node. This node is Business Edition working on the UCS M3 Server.

They had a RAID Card Error. Anyway; They were working on CUCM Subscriber a lot of time. I installed CUCM Publisher from Subscriber. Actually, at the beginning everything was fine. We discover; that the PLM is working in Demo Mode! When I searched a lot of websites I saw; I guess, we need Publisher MAC Add. The CUCM version is v11.5. 

Can I learn Publisher Mac from Subscriber? Is that possible? Also, is The MAC Add enough? Because; this Mac Add is the physical address on the physical M3 Server. But the CUCM was working on the Vmware platform and This platform generally assigns a virtual MAC Address to Virtual Applications.

Shortly; I need to learn the CUCM Publisher MAC Address. 

How can I do that?

Regards.

Was the PLM instance on the publisher? Is the publisher completely dead, or just had a  RAID card failure? If you a separate PLM that is still alive, you could remove the old publisher and register a new publisher that could then use the licenses installed in the PLM. If the PLM was on the publisher and it is not recoverable, you are stuck. TAC could help you rehosting licenses, but it seems unlikely you have a contract if you are still running on M3 hardware.

Dear Elliot,

Unfortunately, The Publisher is dead, the motherboard, Graphic Card everything was gone. Normally, The PLM was working on the Publisher node. I found Phycall MAC on the Mother Board. But I need the Virtual Mac for Virtual Publisher Appliance. Unfortunately, I couldn't find it. Maybe; this is registered anywhere on The Subscriber Node. But I don't have any idea How can I find that? Also M3 Server is dead to They don't have SmartNET.

My suggestion would be to by a similar M3 server off eBay. Just because the system board is dead doesn't mean the drives are dead. You might be able to move the drives to a new server. It appears you already realize this, but you are going to be doing this all without a net. Be as careful as you can!

Dear Elliot, It is not a solution to buy a new (or old) M3. Maybe the problem will be growing up. Cause; I can not use the old HDD on the new M3 server I don't have any idea to set up RAID Card: RAID 0 RAID 1 Which one?

[Elliot Dierksen]

The RAID card reads the volume config from the drives. If you put the drives in a working server (while powered off) in the same position as they were in old server, it should read the RAID volume config from there. You can't configure a volume in the controller if no drives are present.

AFAIK the subscriber node(s) does not keep a record of the publisher MAC address. From what I can think of there is no way to get the VMs virtual MAC address other than looking at the VM. Even though there was a RAID card error don’t you have the hard drives where the VM would be placed on? With that you should be able to get VM and simply put it on some other hardware and start it up. If that doesn’t work you should at least have access to the vmx file where the MAC address would I believe be recorded.

Dear Roger, I can use the old HDD disks on different VM Platforms. But I don't know what is RAID Setting for CUCM or M3 Server. For the exam; is RAID 0 enough? I don't want to lose data on the old HDD. 

[Elliot Dierksen]

You are limited with drives that are used with a hardware RAID controller. They all (to the best of my knowledge) put some custom information on the drives, so they don't work the same with a different RAID controller. There is no standard for this, it is all vendor proprietary. I don't think you will be able to read those drives on a different hardware platform.

Thanks a lot for your answers. Unfortunately; We opened a new case to Cisco. We were requested to new licence files. Cisco gives us new files. Because; CUCM v11.5 was in Perpetual License format. FYI

But; my situation actually It still keeps me busy.
