Disconnect a managed host to temporarily suspend all vCenter Server monitoring and management activities.
- In the vSphere Web Client, navigate to the host in the vSphere inventory.
- Right-click the host and select Disconnect.
- In the confirmation dialog box that appears, click Yes.
If the managed host disconnects successfully, the disconnected designation is appended to the object name in parentheses, and the object is dimmed. All associated virtual machines are similarly dimmed and labeled.
