Changing the Failover Mode of the VMware Cloud Director Appliance

By default, the VMware Cloud Director appliance is in manual failover mode and if the primary database service fails, you must initiate the failover action. You can change the failover mode to automatic by using the appliance API.

Starting with VMware Cloud Director 10.1, if the primary database service fails, you can enable VMware Cloud Director to perform an automatic failover to a new primary. See Automatic Failover of the VMware Cloud Director Appliance.

The failover mode is set to automatic or manual by using the VMware Cloud Director appliance API. See the Failovermode section of the VMware Cloud Director Appliance API Schema Reference.

For clusters configured with automatic failover, after you deploy one or more additional cells, you must use the appliance API to reset the failover mode of the cluster to automatic. If you do not reset the failover mode of the cluster, the failover mode across the nodes becomes inconsistent.
