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)

Presentations and Discussion Slides:

Development Status

Proposed Dublin scope presented Dec 20, 2018 to the 5G UC meeting.

Project	PTL/Contancts	Description
APPC SDNC CCSDK	Takamune Cho Dan Timoney	~~Support vendor-specific mapping of upgrade APIs to NETCONF requests in addition to other options~~. Support of roll-back API for PNF, New DG needed. Impact to SO building blocks and SDNC. LCM API payload and playbook enhancements for S/W upgrade for alignment with 3GPP S/W management APIs in ansible playbooks PNF S/W upgrade workflow design and test (Stretch goal)
VF-C	Yan Yang Xiang Li[CMCC]	No Impact
SO VID	Seshu Kumar Mudiganti ittay	~~Provide re-usable workflows and building blocks for PNF SW upgrade~~ ~~Trigger upgrade workflow from GUI~~
Integration	Yang Xu	No impact
External Controller	Enbo Wang wangyaoguang	Support for 3GPP API calls for sw download, install and activate.

Project Impacts	Description	JIRA Links
SDNC/CCSDK	Add SDNC LCM action - rollback	SDNC-664 - Getting issue details... STATUS
	complete rollback LCM action for PNF S/W upgrade	SDNC-669 - Getting issue details... STATUS
	create a DG for PNF S/W upgrade	SDNC-670 - Getting issue details... STATUS
	provide corresponding ansible playbook for rollback operation	SDNC-671 - Getting issue details... STATUS
	Extend PNF upgrade-software operation by leveraging sub-operations from 3GPP (like download/install/activate)	SDNC-677 - Getting issue details... STATUS
External Controller	Support swFallback/download/install/activate operations	NA

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.
