vCloud Director puts the host into maintenance mode and moves all of its virtual machines to other hosts in
the same cluster.
Prepare or Unprepare an ESX/ESXi Host
When you add an ESX/ESXi host to a vSphere cluster that vCloud Director uses, you must prepare the host
before a provider virtual datacenter can use its resources. You can unprepare a host to make it unavailable
for use in the vCloud Director environment.
For information about moving virtual machines from one host to another, see “Move Virtual Machines from
one ESX/ESXi Host to Another,” on page 107.
You cannot prepare a host that is in lockdown mode. After you prepare a host, you can enable lockdown
mode.
Prerequisites
Disable the host and ensure that no virtual machines are running on the host.
Procedure
1 Click the Manage & Monitor tab and click Hosts in the left pane.
2 Right-click the host name and select Prepare Host or Unprepare Host.
3 If you are preparing a host, type a user name and password and click OK.
vCloud Director prepares or unprepares the host for all provider virtual datacenters that use its resources.
