Hi vladispay,

I guess you are talking rabbit_ha_queues options. It is already marked as

                help='Try to use HA queues in RabbitMQ (x-ha-policy: all). '
                'If you change this option, you must wipe the RabbitMQ '
                'database. In RabbitMQ 3.0, queue mirroring is no longer '
                'controlled by the x-ha-policy argument when declaring a '
                'queue. If you just want to make sure that all queues
(except '
                'those with auto-generated names) are mirrored across all '
                'nodes, run: '
                """\"rabbitmqctl set_policy HA '^(?!amq\.).*' """
                """'{"ha-mode": "all"}' \""""),

In kolla, we configure a global ha-mode policy through its definition.json
file in rabbitmq, please check[1]
