Environment

VMware HCX

Cause

The vCenter is not case sensitive, but HCX has this gap where it's doing case sensitive check on the tag names and deducing that the relevant tag is missing on target and trying to create a new one. But vCenter flags the error that the tag already exists.

Resolution

This is a known issue impacting VMware HCX and this will be resolved in future releases.
