Figure 7-1 illustrates the process for removing a managed host from vCenter Server. In the example here, notice
the lost link between vCenter Server and the removed managed host, while the managed host files remain on
the datastore.

Remove a Managed Host from vCenter Server
Remove a managed host from vCenter Server to stop all vCenter Server monitoring and management of that
host.
If possible, remove managed hosts while they are connected. Removing a disconnected managed host does
not remove the vCenter Server agent from the managed host.
Prerequisites
Make sure NFS mounts are active. If NFS mounts are unresponsive, the operation fails.
Procedure
1 From the vSphere Client connected to a vCenter Server system, display the inventory.
2 (Optional) If the host is part of a cluster, you must put it in maintenance mode.
a
Right-click the managed host in the inventory and select Enter Maintenance Mode from the pop-up
menu.
b On the confirmation dialog, click Yes.
The host icon changes and the term “maintenance mode” is added to the name in parentheses.
3 Right-click the appropriate host in the inventory panel, and select Remove from the pop-up menu.
