1 INTRODUCTION

1.1 Purpose

This document describes how to create and maintain environments of any type (Rtap, Qsemu, LCU) with respect to the VLT standards. It contains the instructions for the VLT-tools to support these tasks, which are part of the workstation-based vcc and envs modules, and the LCU-based boot enabler, named lcuboot.

The environment setup and configuration features are provided as:

1. a set of GUI panels for manual control of environments.

These interactive panels make use of:

2. a set of WS commands to create, start, stop, delete, and check all types of environments. These commands are also used by higher level procedures (e.g. automatic test support tool kit).

For LCUs, these commands can generate files which are compatible with:

3. a set of LCU library functions that facilitate the boot procedure.

1.2 Scope

The User Manual part of this document describes the following VLT software modules:

· lcuboot from version 1.29 for LCU booting functions

· vcc from version 2.7 for environment setup and configuration

· envs from version 1.17 for basic environment creation from templates

The document assumes that the reader has a good knowledge of UNIX and the VxWorks operating systems.
