Environment

VMware vRealize Suite Lifecycle Manager 8.x

Cause

Lifecycle Manager is expecting license data which does not existing in the response coming from vRealize Network Insight. There was a change made to Lifecycle Manager 8.10 to support both core and cpu based licenses. vRealize Network Insight version 6.8 returns the response in expected format , however the versions  6.7 and below do not.

Resolution

The issue is resolved in vRealize Network Insight 6.8 release

Workaround:
To workaround the issue you can manually replace the license in vRealize Network Insight and then perform an inventory sync of Network Insight in Lifecyle Manager This will create a locker entry for the license in Lifecycle Manager and also associate it with the relevant product
