Chapter 2. Process Description

Red Hat OpenStack Platform (RHOSP) includes the drivers required for all Dell devices supported by the Block Storage service. In addition, director also has the puppet manifests, environment files, and Orchestration templates necessary for integrating the device as a back end to the overcloud.

Configuring a single Dell device as a back end involves editing the default environment file and including it in the overcloud deployment. This file is available locally on the undercloud, and can be edited to suit your environment.

After you edit this file, invoke it through director. Doing so ensures that it persists through future overcloud updates. The following sections describe this process in greater detail. In addition, the default environment file already contains enough information to call the necessary puppet manifests and Orchestration (heat) templates that configure the rest of the required Block Storage settings.
