KDM70 Controller User Guide

This document is a user guide for the KDM70 Controller, a mass storage product within Digital's Storage Architecture (DSA) family, designed for XMI-based VAX and RISC systems.

The guide covers:

• General Information: Introduces the KDM70 controller, detailing its performance optimization features (like seek ordering, overlapped seeks, dual data channels) and data integrity features (Error Detection/Correction Code, Bad Block Replacement). It also outlines configuration guidelines, architecture (MSCP/TMSCP protocols, SDI/STI buses, XMI bus interface), and specifications. Safety precautions for electrostatic discharge (ESD) are also included.
• Installation: Provides step-by-step instructions for installing the KDM70 controller's two modules (processor and SI interface) into adjacent XMI backplane slots, and connecting the associated I/O bulkhead distribution panels and SDI/STI cables. It specifies minimum operating system versions required (VMS, ULTRIX) and lists necessary parts.
• Customer Acceptance and Verification: Describes procedures for verifying the controller's functionality post-installation. This involves running internal self-tests (MIST) and a subsystem exerciser program (ILEXER) from either the VAX Diagnostic Supervisor or DUP connection. It also explains how to interpret LED error codes for basic error detection.
• Code Update Utility: Details the use of the EVRLM utility to install new versions of the KDM70 controller's software and provides common error messages encountered during this process.

Overall, the document serves as a comprehensive manual for the proper installation, testing, and firmware updating of the KDM70 Controller.
