Use the vSphere Client to disconnect a managed host from vCenter Server.
- From the vSphere Client connected to a vCenter Server system, display the inventory and click the managed host to disconnect.
- Right-click the host and select Disconnect from the pop-up menu.
- In the confirmation dialog box that appears, click Yes.
If the managed host is disconnected, the word “disconnected” is appended to the object name in parentheses, and the object is dimmed. All associated virtual machines are similarly dimmed and labeled.
