Adding another processor to our CUC virtual machine?

[ryabutler]

Hi,

I have a quick question I want to confirm.  We are running Cisco Unity Connection 8.6 as a virtual machine on one of our ESXi server.  Right now that virtual machine is running with one processor and we want to adjust it to use 2 processors.

My question is, if I change the processor from 1-2 will that cause any issues with its current licensing (e.g. do I need a new license)?  Or anything else I need to be aware of if we make this change?

Thank you!

No licensing will be affected, though re-sizing is supported you have the follow some guidelines as described here:

http://docwiki.cisco.com/wiki/Unified_Communications_VMware_Requirements#Resize_Virtual_Machine

You cannot just add CPUs unless you align it to a specific OVA, which might be an issue fof UCXN deployments as there is no way to resize disk space, and disk space varies from 1 OVA to another.

HTH,

Actually adding vCPUs to Unity and CUC is not supported as outlined in the link Chris provided

• Support for adding virtual hardware resources (similar to moving from a less powerful server to a more powerful server, such as MCS 7825 ⇒ MCS 7845) depends on which resource, and which UC product:

• Adding vCPU is supported for all apps except Unity and Unity Connection, but requires VM to be shutdown first.
• Adding vRAM is supported but requires VM to be shutdown first.
• Adding vDisk is not supported as it would require re-partitioning by the application.

You need to DRS your CUC VM and then rebuild it with the amount of vCPUs you want, so you can then restore your DRS.
