StorageWorks Array Contr, HS Family of Array Contrls User's Gde

This document is the StorageWorks™ Array Controllers HS Family of Array Controllers User's Guide, specifically for the HSJ30, HSJ40, HSD30, and HSZ40 array controllers. It is intended for customers, system managers, and Digital Multivendor Services engineers responsible for installing and using these array controller subsystems.

The guide provides:

• An overview of the HS controller family, their physical descriptions, and key features, including various read cache module options, dual data link capabilities (for HSJ), and specifications. It details how these controllers are housed in StorageWorks shelves (BA350-MA, BA350-SB) and cabinets (SW800-series, SW500-series).
• Technical descriptions of the controller hardware and the Hierarchical Storage Operating Firmware (HSOF), explaining core functions, host interconnect protocols (CI, DSSI, SCSI-2), and value-added features like RAID 0 and RAID 1a support, failover for dual-redundant HSJ/HSD30 configurations, and device warm swap.
• Detailed instructions for installation, covering customer site preparation (power, environmental), tools needed, electrostatic discharge (ESD) protection, handling guidelines for components, and procedures for installing preconfigured or custom-ordered subsystems, including cabling.
• Controller operations and management, describing initialization sequences, use of the Command Line Interpreter (CLI) for configuration (defining devices, storage sets, logical units), interpreting Operator Control Panel (OCP) buttons and LEDs for status and error codes, and performing warm swap procedures for disks, tapes, and controllers.
• Diagnostics and utilities, such as DILX (Disk Inline Exerciser), TILX (Tape Inline Exerciser), VTDPY (performance display), and CONFIGURE (automatic device configuration), to help with troubleshooting and system analysis.
• Operating system support for OpenVMS (VAX and AXP) and DEC OSF/1 AXP, including specific considerations for boot devices, error reporting, and virtual terminal access.

The document also includes appendices with option order numbers, a comprehensive CLI command reference, descriptions of RAID technology levels, and a glossary of terms. Throughout, it emphasizes important cautions and notes regarding data integrity and proper procedures.
