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 vDC 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 71.
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 vDCs that use its resources.
Upgrade an ESX/ESXi Host Agent
vCloud Director installs agent software on each ESX/ESXi host in the installation. If you upgrade your ESX/ESXi
hosts, you also need to upgrade your ESX/ESXi host agents.
Procedure
1 Click the Manage & Monitor tab and click Hosts in the left pane.
2 Right-click the host name and select Upgrade Host.
Repair an ESX/ESXi Host
If the vCloud Director agent on an ESX/ESXi host cannot be contacted, try to repair the host.
Procedure
1 Click the Manage & Monitor tab and click Hosts in the left pane.
2 Right-click the host name and select Repair Host.
Managing vSphere Datastores
You can enable or disable vSphere datastores in the vCloud Director system, configure low disk space warnings
for datastores, and remove datastores from the vCloud Director system.
The only way to add a datastore to vCloud Director is to add it to a provider vDC. See “Add Storage Capacity
to a Provider vDC,” on page 41.
Enable or Disable a Datastore
You can enable or disable a datastore that has been added to a provider vDC. You must disable a datastore
before you can remove it from vCloud Director.
When you disable a datastore, you cannot start vApps that are associated with the datastore or create vApps
on the datastore.
