DECdfs for OpenVMS

This document is the DECdfs for OpenVMS Installation Guide, Version 2.4, published in January 2005. It provides comprehensive instructions for installing DECdfs software on OpenVMS Alpha Version 8.2 and OpenVMS I64 Version 8.2 systems, supporting DECnet Phase IV or V.

The guide covers three main areas:

1. Installation Prerequisites: Details the necessary hardware (DECnet network), software, license registration (PAK), disk space requirements, system generation (SYSGEN) parameter adjustments (e.g., nonpaged pool, global pages, channel count), account and quota requirements, and configuration planning. This includes setting up the DECdns Distributed Name Service (for DECnet Phase V and VAX Phase IV systems) and considerations for OpenVMS Cluster environments. It also advises on installing over previous DECdfs versions and potential reboots.
2. Installation and Verification: Outlines the step-by-step interactive VMSINSTAL procedure. This involves logging in as a system manager, mounting the distribution media, confirming system environment, and making choices for client-only or client/server software installation. It also describes how to run the Installation Verification Procedure (IVP) to ensure correct installation and operation, and explains various installation-related messages.
3. Postinstallation Procedures: Provides guidance for tasks after installation, such as re-running the IVP, editing system startup command files (like DFS$STARTUP.COM and DFS$CONFIG.COM) to configure parameters and access points, setting additional DECnet and system parameters, and creating OpenVMS proxy accounts for client access. It also explains how to change DECdfs configurations (e.g., from client-only to server), delete server software from client-only systems to free space, check cluster systems, and handle errors or report problems.

The document emphasizes reading the release notes, backing up the system, and meeting all prerequisites for a successful DECdfs deployment.
