If you want to stop a cell and let users know that you are performing maintenance, you can turn on the maintenance message.
When the maintenance message is turned on, users who try to log in to the cell from a browser see a message stating that the cell is unavailable because of maintenance. Users who try to reach the cell using the vCloud API receive a similar message.
- Stop the cell by running the service vmware-vcd stop command.
- Run the /opt/vmware/vcloud-director/bin/vmware-vcd-cell maintenance command.
