Symptoms:
- vCenter managing multiple vSAN clusters.
- vCenter upgrade to 7.0U3c or higher.
- Multiple Virtual machines reporting virtual objects with "Unknown" object state in vSAN Skyline health > Virtual objects.
After upgrading vCenter from 6.x/7.x to 7.0 U3c or higher, vSAN Skyline Health > Virtual Objects is reporting objects with "Unknown" object state, the UI shows the VMs names, but these VMs are in another vSAN cluster.
The environment does not have remote storage configured and these VMs do not have VMDKs hosted in the vSAN datastore in question.
