Enabling Automatic Failover Automatic failover can only be enabled from the active node. Log on to QNE on the active node. Open HA Manager. Go to HA Settings > Policies. Select Enable automatic failover. Select one or more Failover Events, any of which would trigger failover. Optional: Select Enable automatic failback. Note: This setting allows the original active node device to automatically resume the active node role once it has been repaired after a failover. Click Apply. HA Manager enables automatic failover.
