For this scenario, the CONTROLLER_ACTOR is set for SDNC client for the API selection decision. +* Service instantiation is completed, including PNF PnP. It means a PNF instance is in operation and is avaibale for ONAP (maybe via EMS). +* ONAP Controller (SDNC and ansible server) and DMaaP are ready to use. It means necessary ansible connection and DMaaP topics are ready. +* EMS has direct ansible interface to the ansible server. The underlying protocol is SSH. + +At run time, the service provider in R6 can use CLI to trigger the PNF in-place software upgrade procedure by selecting the existing PNF software upgrade workflow or uploading a custom workflow, as well as an identifier of a PNF instance, the target software version and optional json-formatted payload. + +Then the software upgrade workflow is executed as follows: + +a. SO sends request(s) with input {action, action-identifiers, common header, and optional payload} to SDNC API handler using traditional LCM API. +b. SDNC API handler executes corresponding DG and sends requests to the ansible server. +c. The ansible server executes ansible playbook with the EMS. Then EMS is responsible of software upgrade procedure of the selected PNF instance. +d. Repeat above steps for each SO building block in the corresponding PNF software upgrade workflow. + +Test Status and Plans +~~~~~~~~~~~~~~~~~~~~~ + +To see information on the status of the test cases, please follow the link below: + +`Enhancement on PNF software upgrade using Ansible Test Status <https://wiki.onap.org/pages/viewpage.action?pageId=64007357#EnhancementonPNFS/WUpgradeusingAnsible-TestStatus>`_ |
