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.
- Click the Manage & Monitor tab and click Provider VDCs in the left pane.
- Right-click the provider virtual datacenter name and select Open.
- Click the Hosts tab.
- Right-click the host name and select Enable Host or Disable Host.
