5G PNF Software Upgrade

Description

The 5G PNF Software upgrade use case shows how users/network operators can modify the software running on an existing PNF. This use case is one aspect of Software Management. This could be used to update the PNF software to a newer or older version of software.

How to Use

Upgrading PNF (instance) software requires the user/network operator to trigger the upgrade operation from the UI, e.g. VID or UUI. In Cacablanca, users need use ONAP Controllers GUI to trigger the LCM opeations, like pre-check, post-check and upgrade. After receiving the API requests, the ONAP controllers will communicate to the external controller(EC) through south-bound adaptors, which is Ansible in R3.

Note that, both APPC and SDNC in R3 supported Ansible. Taking SDNC and Prechecking as an example, the steps are as follows:

  1. In ansible server container, prepare the ssh connection conditions to the external controller, both ssh key file and ansible inventory configuration;

2) In sdnc controller container, update the dg configuration file: lcm-dg.properties. For example: :: 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

3) Login controller UI, access the pre-check LCM operation and send request. Post upgrade-pre-check with the following request body: :: {

“input”: {

“common-header”: { “timestamp”: “2018-10-10T09:40:04.244Z”, “api-ver”: “2.00”, “originator-id”: “664be3d2-6c12-4f4b-a3e7-c349acced203”, “request-id”:”664be3d2-6c12-4f4b-a3e7-c349acced203”, “sub-request-id”: “1”, “flags”: {

“force” : “TRUE”, “ttl” : 60000

}

}, “action”: “UpgradePreCheck”, “action-identifiers”: {

“vnf-id”:”5gDU0001”

}, “payload”: “{“pnf-flag”:”true”, “pnf-name”: “5gDU0001”,”pnfId”: “5gDU0001”, “ipaddress-v4-oam”: “EC_IP_address”,”oldSwVersion”: “v1”, “targetSwVersion”: “v2”, “ruleName”: “r001”, “Id”: “10”, “additionalData”:”{}”}”}}

  1. The HTTP API response code 200 and LCM retured code 400 (See APPC return code design specification) indicate success, otherwise failed.
