| Test Case Id | V00015 |
| Test Case Name | VoLTE Auto-healing |
| Description | This test covers the closed loop with alarm correlation and auto-healing |
| Release | Amsterdam |
| Preconditions | - VoLTE service has been instantiated
- VoLTE closed loop has been configured and started
- SPGW VNF supports event generation
- VNF guest OS supports event generation
- MultiVIM supports event collection from guest OS and event forwarding
|
| Testing Steps | - Use Robot test script to Manually shutdown standby MPU VM inside SPGW VNF. This should trigger the VNF and VIM to generate alarms
|
| Expected Results | - EMS collects standby MPU offline event from SPGW VNF and sends the event to VFC
- MultiVIM doesn't receive heartbeat event from standby MPU guest OS for a period of time and triggers alarm which is sent to DCAE VES collector
- Holmes receives MPU offline events
- Holmes receives MPU guest OS heartbeat missing events
- Holmes does correlation of the two types of events and generate one signature event and sends it to Policy
- Policy triggers provisional policy and healing action is sent to VFC
- VFC uses SVNFM driver to heal standby MPU VM
- Standby MPU is healed
- Clear event is sent from SPGW VNF about standby MPU back online
- Heartbeat from standby MPU VM is received by MultiVIM and clear event is sent by MultiVIM about heartbeat recovery
- Holmes does the event correlation and sends Clear signature event to Policy
- Policy stops the healing action
