1. Create new environment
2. Choose Neutron, VLAN
3. Choose Ceph for images
4. Add 3 controller, 1 compute, 1 cinder, 3 ceph
5. Move Storage network to eth1
6. Move Management network to eth2 and untag it
7. Deploy the environment. It was successful
8. Run OSTF tests. It was successful
9. SSH to promary controller and destroy system:
echo 1 > /proc/sys/kernel/sysrq
echo u > /proc/sysrq-trigger
10. Primary controller became 'offline' on UI but I can ssh to it
11. Start OSTF tests. Only test "RabbitMQ availability" has failed with error: Number of RabbitMQ nodes is not equal to number of cluster nodes.

Cause is method list-nodes includes only online nodes (list_https://github.com/stackforge/fuel-ostf/blob/master/fuel_health/tests/ha/test_rabbit.py#L84)

May be we need to correct OSTF test.
