+|OpenStack Controll Node abnormally shutdown High Availability |
++==============+==============================================================+
+|test case id | OPNFV_YARDSTICK_TC025_HA: OpenStack Controll Node abnormally |
+| | shutdown |
++--------------+--------------------------------------------------------------+
+|test purpose | This test case will verify the high availability of control |
+| | nodethe. When one of the control node abnormally shutdown, |
+| | the service provided by it should be OK. |
++--------------+--------------------------------------------------------------+
+|test method | This test case shutdowns a specified control node with some |
+| | fault injection tools, then checks whether all services |
+| | provided by the control node are OK with some monitor tools. |
++--------------+--------------------------------------------------------------+
+|attackers | In this test case, an attacker called "host-shutdown" is |
+| | needed. This attacker includes two parameters: |
+| | 1) fault_type: which is used for finding the attacker's |
+| | scripts. It should be always set to "host-shutdown" in |
+| | this test case. |
+| | 2) host: which is the name of a control node being attacked. |
+| | |
+| | e.g. |
+| | -fault_type: "host-shutdown" |
+| | -host: node1 |
++--------------+--------------------------------------------------------------+
+|monitors | In this test case, one kind of monitor are needed: |
+| | 1. the "openstack-cmd" monitor constantly request a specific |
+| | Openstack command, which needs two parameters |
+| | 1) monitor_type: which is used for finding the monitor class |
+| | and related scritps. It should be always set to |
+| | "openstack-cmd" for this monitor. |
+| | 2) command_name: which is the command name used for request |
+| | |
+| | There are four instance of the "openstack-cmd" monitor: |
+| | monitor1: |
+| | -monitor_type: "openstack-cmd" |
+| | -api_name: "nova image-list" |
+| | monitor2: |
+| | -monitor_type: "openstack-cmd" |
+| | -api_name: "neutron router-list" |
+| | monitor3: |
+| | -monitor_type: "openstack-cmd" |
+| | -api_name: "heat stack-list" |
+| | monitor4: |
+| | -monitor_type: "openstack-cmd" |
+| | -api_name: "cinder list" |
++--------------+--------------------------------------------------------------+
+|metrics | In this test case, there is one metric: |
+| | 1)service_outage_time: which indicates the maximum outage |
+| | time (seconds) of the specified Openstack command request. |
++--------------+--------------------------------------------------------------+
+|test tool | None. Self-developed. |
++--------------+--------------------------------------------------------------+
+|references | ETSI NFV REL001 |
++--------------+--------------------------------------------------------------+
+|configuration | This test case needs two configuration files: |
+| | 1) test case file: opnfv_yardstick_tc019.yaml |
+| | -Attackers: see above "attackers" discription |
+| | -waiting_time: which is the time (seconds) from the process |
+| | being killed to stoping monitors the monitors |
+| | -Monitors: see above "monitors" discription |
+| | -SLA: see above "metrics" discription |
+| | |
+| | 2)POD file: pod.yaml |
+| | The POD configuration should record on pod.yaml first. |
+| | the "host" item in this test case will use the node name in |
+| | the pod.yaml. |

+|post-action | It is the action when the test cases exist. It restarts the |
+| | specified control node if it is not restarted. |
++--------------+------+----------------------------------+--------------------+
+|test verdict | Fails only if SLA is not passed, or if there is a test case |
+| | execution problem. |
