KFMSA Module Installation and User Manual

This "KFMSA Module Installation and User Manual" provides comprehensive instructions for installing, configuring, and maintaining the KFMSA module, an XMI (Extended Memory Interconnect) storage adapter, within Digital's VAX 6000 and VAX 9000 series systems. This module connects the host system to DSSI (Digital Storage System Interconnect) based Integrated Storage Elements (ISEs) via two DSSI buses.

The document covers:

• Hardware Installation: Detailed steps for physically installing the KFMSA module into the XMI card cage, emphasizing critical static electricity precautions, system shutdown procedures, and proper cabling between the XMI backplane and I/O bulkhead. It outlines the various KFMSA cable kits available and their use in different configurations, including crucial details on bus termination and XMI slot restrictions for specific VAX models.
• Power-On Self-Test (POST): Description of the module's self-diagnostic test, its LED indicators for status and error reporting, and the meaning of fatal error codes.
• Configuration Concepts: Explains the physical address requirements (XMI Node Number, DSSI Bus Number, DSSI Node ID) and software parameters for ISEs (System ID, Node Name, MSCP/TMSCP Unit Number, Allocation Class) that are essential for proper communication within both single-system and VAXcluster environments.
• Software Configuration: Provides step-by-step guides for setting device parameters using VAX Diagnostic Supervisor (VAX/DS) utilities like EVCXE (primarily for VAX 6000) and EVCXF (recommended for VAX 9000). These utilities enable users to size the DSSI configuration, read/modify parameter values, and run diagnostics. Specific procedures are detailed for single-system and DSSI VAXcluster setups, highlighting the necessity for unique node IDs and consistent allocation classes across clustered systems.
• Booting VMS: Procedures for booting the VMS operating system from a DSSI device connected via the KFMSA module on both VAX 6000 and VAX 9000 systems, including minimum console code revision requirements and command syntax.
• EEPROM Update Utility (EVUCM): Instructions for using this utility to access and update the KFMSA module's EEPROM (firmware and diagnostics).
