APIC Data Layer Partially Diverged


After trying to join APICs from a secondary POD, I got the APIC Data Layer Partially Diverged Error:

APIC Data Layer Partially Diverged

In my case this was because I had the “Contract Viewer” app installed on the primary APICs. When the secondary site APICs tried to join the cluster, the 3rd party APP caused this error. I had to remove the APP and reinstall it to allow the secondary POD APICs to join properly.
