Cluster licensing after CPU upgrade

Hi 

I recently added a second CPU and expanded the memory in each node of a two-site Nutanix AHV environment running Metro Availability. Each site has its own three-node cluster and Prism Central instance.

The CPU upgrade increased each node from 16 to 32 physical cores, so each cluster went from 48 to 96 cores. The customer purchased additional NCI Pro and Advanced Replication licenses to cover the extra 48 cores per cluster.

After the physical upgrade I followed the manual licensing workflow:

  1. Exported the Cluster Summary File (CSF) from Prism Central

  2. Uploaded it to the Nutanix Support Portal under Licensing → Manage Licenses and selected the new licenses

  3. Downloaded the generated License Summary File (LSF) and uploaded it back to the same Prism Central instance

I repeated the same process for both Prism Central but they still report the clusters as out of compliance, with 96 physical cores detected and 48 licensed on each cluster.

Notice that when checking the portal licensing final summary it shows 96 cores assigned to the correct cluster UUID but Prism Central still shows 48 after applying the LSF.

So what am I doing wrong?

Thanks!
