This is a continuation of the use case started in Casablanca: 5G - PNF Software Update
Background (R3 Casablanca)
In Casablanca, the UC leveraged the Ansible adaptor of ONAP controller to implement three S/W upgrade related operations for 5G PNFs. As an important feature the new workflow supports an External Controller (EC) in the execution of these operations. All these operations have shared the same LCM APIs with VNF S/W upgrade with PNF specific parameters passed in the API payloads. The corresponding DGs of LCM APIs are updated. The operations are:
- /operations/LCM:upgrade-pre-check
- /operations/LCM:upgrade-software
- /operations/LCM:upgrade-post-check
Dublin Scope
For Dublin, the target of this UC includes:
- 3GPP Software Management API alignment
- South-bound of SDNC: Extend upgrade-software operation by leveraging sub-operations from 3GPP (like download/install/activate).
- North-bound of SDNC: Rollback/fallback API support for 5G PNF
- Workflow support for PNF in-place SW upgrade in SO (stretch goal)

Requirements Impact
CCSDK → Changes in LCM.yang file
SDN-C → (1) New ansible playbooks, (2) New DG for rollback
EC → New substeps such as sw download, install and activate
API changes
- Yang model changes to current LCM:rollback action in CCSDK (mandatory fields in rollback action will be optional to make the LCM:rollback action more generic, optional output payload field is added)
- Definition of rollback input and output payloads for 5G PNF specific rollback
- Possible payload changes into existing API /operations/LCM:upgrade-software
- sw download, install and activate APIs in southbound of SDNC (to EC) as part of Ansible playbook for LCM:upgrade-software API.

Preparation
1. Modify the file /opt/onap/sdnc/data/properties/lcm-dg.properties in sdnc container as follows:
| -lcm.pnf.upgrade-pre-check.playbookname=ansible_precheck_pnf -lcm.pnf.upgrade-post-check.playbookname=ansible_postcheck_pnf -lcm.pnf.upgrade-software.playbookname=ansible_upgradesw_pnf -lcm.pnf.rollback.playbookname=ansible_rollback_pnf +lcm.pnf.upgrade-pre-check.playbookname=ansible_huawei_precheck +lcm.pnf.upgrade-post-check.playbookname=ansible_huawei_postcheck +lcm.pnf.upgrade-software.playbookname=ansible_huawei_upgrade +lcm.pnf.rollback.playbookname=ansible_huawei_rollback |
And then restart the sdnc container.
2. Add the following line in the file in /opt/ansible-server/Playbooks/Ansible_inventory in ansible-server container:
| 192.168.35.83 ansible_connection=ssh ansible_ssh_user=ubuntu ansible_ssh_private_key_file=/home/ansible/.ssh/ssh_key_file |
Where ssh_key_file is private key of SSH user ubuntu at host 192.168.35.83.
Host 192.168.35.83 is the EMS Simulator.
