The vSphere Web Client does not display the vCenter Server systems that you expect to see in the inventory.
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.
In releases of vSphere before vSphere 5.1, you log into individual vCenter Server systems with the vSphere Client. Unless you work in Linked Mode, only one instance of vCenter Server appears in the inventory.
In vSphere 5.1 and 5.5, 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, if the server is registered with the same lookup service as the vSphere Web Client.
- Log in to the vSphere Web Client as a user with permissions on the vCenter Server system.
The vCenter Server system will not appear in the inventory if you do not have permissions on it. For example, if you log in as the vCenter Single Sign On administrator user, you might not have permissions on any vCenter Server system.
- Verify that the vCenter Server system is registered with the same lookup service as the vSphere Web Client.
The vSphere Web Client discovers only vCenter Server systems that are registered with the same lookup service.
