The vSphere Web Client does not display the vCenter Server systems that you expect to see in the inventory.
Problem
When you log in to the vSphere Web Client, the inventory appears to be empty or the vCenter Server system you expected to see does not appear.
Cause
In vSphere 5.1 and later, you log into the vSphere Web Client to view and manage multiple instances of vCenter Server. Any vCenter Server system on which you have permissions appears in the inventory when the server is registered with the same Component Manager as the vSphere Web Client.
