Chapter 3. Defining a single back end

Important

This section describes the deployment of a single back end. Deploying multiple instances of a Dell EqualLogic back end requires a custom back end configuration. For more information, see the Custom Block Storage Back End Deployment Guide.

To define a single Dell EMC PS Series back end, complete the following steps:

  1. Copy the default cinder-dellps-config.yaml file from the core heat template collection: 

    $ cp /usr/share/openstack-tripleo-heat-templates/environments/cinder-dellps-config.yaml ~/templates/
  2. Edit the values in the parameter_defaults section of the ~/templates/cinder-dellps-config.yaml file to define your Dell EMC PS Series back end. Use the following table to understand how to define each parameter:
