VAX 6000/SF7x/SF3x Embedded Storage Installation Guide

This document, the "VAX 6000/SF7x/SF3x Embedded Storage Installation Guide" (Third Edition, July 1992), provides step-by-step procedures for Digital Customer Service Engineers to install and operate SF7x and SF3x DSSI disk storage enclosures embedded within the VAX 6000 Series Processor Cabinet.

The guide covers comprehensive aspects of the installation process, including:

• Safety Precautions: Highlighting hazards, ESD, and system grounding.
• Storage Options: Describing the various SF7x and SF3x disk enclosure models, their specifications, and available upgrade kits, noting their "through-bus" and "split-bus" operational modes.
• Cabinet Preparation: Instructions for preparing the VAX 6000 cabinet, which includes replacing the front door, installing logos, potentially upgrading the H405 power controller, and installing the KFMSA (XMI-based DSSI Controller Module).
• Hardware Installation: Detailed procedures for physically mounting the storage enclosures into the cabinet, including the installation of EMI/RFI spring clips, guide rails, and shims.
• Configuration and Cabling: Steps for configuring the Operator Control Panel (OCP) and DSSI ID switches for both SF7x and SF3x enclosures, as well as comprehensive cabling procedures for DSSI and power connections.
• Power-On and Verification: Guidance on powering on the newly installed enclosures and performing final checks and tests to ensure proper operation.
• Troubleshooting: A dedicated section on identifying and resolving installation issues, covering OCP fault codes, probable causes, corrective actions, and procedures for removing/replacing disk ISEs (Integrated Storage Elements).
• Advanced Configurations: Appendices explain how to configure these systems for "Split-Bus/Disk Striping" to enhance I/O performance and how to integrate them into "DSSI VAXcluster Configurations" for shared disk storage among multiple VAX 6000 systems.

The manual is intended for qualified personnel to ensure the correct and safe deployment of these embedded storage solutions.
