Managing vSphere ESX/ESXi Hosts
You can prepare hosts for use with vCloud Director, enable or disable hosts, upgrade, and repair hosts.
Enable or Disable an ESX/ESXi Host
You can disable a host to prevent vApps from starting up on the host. Virtual machines that are already
running on the host are not affected.
To perform maintenance on a host, migrate all vApps off of the host or stop all vApps and then disable the
host.
Procedure
1 Click the Manage & Monitor tab and click Hosts in the left pane.
2 Right-click the host name and select Enable Host or Disable Host.
vCloud Director enables or disables the host for all provider virtual datacenters that use its resources.
Move Virtual Machines from one ESX/ESXi Host to Another
You can move all the virtual machines from one ESX/ESXi host to other hosts in the same cluster. This
ability is useful to unprepare a host, or to perform maintenance on a host without affecting running virtual
machines.
Prerequisites
Disable the host.
