Symptoms

With a traffic-group configured to use HA Group, it is not possible to disable the HA Group to perform targeted failover. Running tmsh run sys failover standby traffic-group traffic-group-1 produces an error: "Unexpected Error: SOD command standby may not be issued for traffic group /Common/traffic-group-1 because it is configured to use HA group."

Impact

Unable to force the traffic-group to standby if HA Group is configured. You would need to change it to use a different mode, such as HA Order.

Conditions

Traffic-group configured to use HA Group. Versions prior to 12.0.0 allowed you to disable the HA Group to do targeted failover.

Workaround

Temporarily change the traffic group to use a different Failover Method such as Load Aware or HA Order in order to failover. Note that this will disable HA Group functionality until the Failover Method is restored.
