After upgrading cisco ISE from 2.1 to 2.6 received error fewer VM license.
Before upgrading the ISE, smart licenses is working fine. Before issue happen, my ISE01 as primary nodes and 02 is secondary nodes. during upgrade, we have technical issue with ISE01 so we decide to promote ISE02 as primary nodes. now the fewer VM license appear error. anyone have a same issue?
ISE 2.1 did not have VM Host licenses. ISE 2.6 now does. Contact your reseller and ask them to help you with your licensing or open a TAC case and they will get it resolved.
The reason why you see this warning message is because the licensing model has changed with ISE starting from version 2.4. Although this warning is just cosmetic, and it won't affect any functionality or performance, it is recommended to install the VM appropriate licenses. The VM licenses are free of charge for all the existing VMs.
Each VM should have its own license installed, and the licenses are per deployment basis, which means depending on the resources running on each VM, it can be determined if the required licenses are for a small, medium or large deployment.
Before your raise the TAC, you should collect the UDIs and the resources used for each VM along with the sales order number of the purchase that has been done for these VMs. I recommend collecting the UDIs from CLI since there are some bugs that might show you wrong UDIs through the UI.
