After you add an ESXi host to a VMware vSphere ® cluster that vCloud Director uses, you must prepare the host before a provider virtual datacenter can use its resources. Unpreparing a host makes it unavailable for use by vCloud Director.
You cannot prepare a host that is in lockdown mode. After you prepare a host, you can enable lockdown mode.
Redeploy all VMs on the host to other hosts. See Move Virtual Machines from one ESXi Host to Another.
Disable the host.
- Click the Manage & Monitor tab and click Hosts in the left pane.
- Right-click the host name and select Prepare Host or Unprepare Host.
If you are preparing a host, supply the username and password of a host administrator, then click OK.
