Planning for the procedure

Background knowledge

This procedure assumes that:

  • you are installing into an existing OpenStack deployment

  • you are using an OpenStack version from Icehouse through to Train inclusive

  • you have some knowledge of VMs and familiarity with OpenStack’s host software

  • you have read the installation guidelines at Initial Setup and have everything you need to carry out the installation.

Reserve maintenance period

This procedure does not require a maintenance period. However if you are integrating into a live network then it is recommended to implement measures to mitigate any unforeseen events.

Plan for service impact

This procedure does not impact service.

People

Anyone can perform these MOP steps.

Tools and access

This document references an external document: the Commissioning VM Documentation. Ensure you have a copy available before proceeding.

Installation Questions

Question More information

Do you have a list of the IP addresses that you intend to give to each node?

Each node requires an IP address for each interface.

Do you have DNS and NTP Server information?

It is expected that the deployed nodes will integrate with the IMS Core NTP and DNS servers.

Method of procedure

Write the SDF

The Solution Definition File (SDF) contains all the information required to set up your ShCM cluster. It is therefore crucial to ensure all information in the SDF is correct before beginning the deployment.

Documentation on how to write an SDF is available in the 'Write an SDF' section of the Commissioning VM Documentation.

The format of the SDF is common to all Metaswitch products, so information can be reused as necessary. However, one element only applies to Rhino VoLTE TAS node types: cds-addresses. This element lists all the Config Data Store addresses. In almost all circumstances, this should be set to all the signaling IPs of the TSN nodes in the deployment.

It is recommended to start from a template SDF and edit it as desired instead of writing an SDF from scratch. An example SDF is included in the CSAR, or can be found here.
