This is a continuation of the use case started in Casablanca: 5G - PNF Software Update
Table of Contents |
---|
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
...
Other areas include VID/UUI and SO for re-usable high-level SW upgrade workflows.
...
- SW upgrade in SO (stretch goal)

Project Impacts | Description | JIRA Links | ||||||||||
SDNC/CCSDK | Add SDNC LCM action - rollback |
| ||||||||||
Complete rollback LCM action for PNF S/W upgrade |
| |||||||||||
Create a DG for PNF S/W upgrade |
| |||||||||||
Provide corresponding Ansible playbook for rollback operation |
| |||||||||||
Extend PNF upgrade-software operation by leveraging sub-operations from 3GPP (like downloadNESw/installNESw/activateNESw) |
| |||||||||||
External Controller | Support swFallback/downloadNESw/installNESw/activateNESw 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.
API Details
(1) Provided by SDN-C/CCSDK:
LCM API Abbre. | HTTP Method | URI | Yang Model Section | Request Example | Response Example | |||||||||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
rollback | Post | /operations/LCM:rollback |
|
| 400: Success
| |||||||||||||||||||||||||||
precheck* | /operations/LCM:upgrade-pre-check |
|
| 400: Success
| ||||||||||||||||||||||||||||
postcheck* | /operations/LCM:upgrade-post-check |
|
| 400: Success
| ||||||||||||||||||||||||||||
upgrade-software* | /operations/LCM:upgrade-software |
|
| 400: Success
|
*: These lcm APIs inherit from R3.
The grammar of filter parameter of rollback API is JsonPath.
New optional parameters of payload for request of upgrade-software API:
- swToBeDownloaded: Used to substitute the targetSwVersion parameter for aligning with 3GPP operation.
- neIdentifier: Used to substitute the pnfId parameter for aligning with 3GPP operation.
- swToBeInstalled: Used to manually specify the software to be installed for aligning with 3GPP operation.
- swVersionToBeActivated: Used to manually specify the software version to be activated for aligning with 3GPP operation.

Test Details
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.
3. Add topics SDNC-LCM-READ and SDNC-LCM-WRITE to DMaaP if they don't exist.
Login Message Router container, and run the following commands:
cd /opt/kafka/bin ./kafka-topics.sh --zookeeper message-router-zookeeper:2181 --create --topic SDNC-LCM-READ --partitions 1 --replication-factor 1 --if-not-exists ./kafka-topics.sh --zookeeper message-router-zookeeper:2181 --create --topic SDNC-LCM-WRITE --partitions 1 --replication-factor 1 --if-not-exists |
