DIGITAL StorageWorks HSZ70 Array Controller HSOF Version 7.0 CLI Reference Manual

This document serves as the Command Line Interface (CLI) Reference Manual for the DIGITAL StorageWorks HSZ70 Array Controller, specifically for HSOF (Hierarchical Storage Operating Firmware) Version 7.0.

Its primary purpose is to provide comprehensive information and guidance for operating the array controller through its command-line interface. The manual defines, explains, and provides examples for a wide range of commands, enabling users to:

• Configure and manage storage components: This includes adding, deleting, and modifying various types of storage containers like disks, CD-ROMs, passthrough devices, and complex RAID configurations such as mirrorsets (RAID level 1), RAIDsets (RAID level 3/5), and stripesets (RAID level 0). It also covers creating and managing logical units and partitions.
• Perform system and controller management: Commands are detailed for initializing containers, renaming components, setting controller parameters (e.g., cache flush timer, host compatibility mode, SCSI IDs, transfer rates), configuring failover modes (dual-redundant, multi-bus), and managing the Environmental Monitoring Unit (EMU).
• Handle errors and diagnostics: Provides commands for clearing various error conditions (invalid cache, lost data, unknown device, unwriteable data) and running diagnostic and utility programs (e.g., CFMENU, CLONE, DILX, CONFIG) for troubleshooting and system support.
• Access help and information: Includes commands for getting help on CLI usage and displaying detailed information about devices, storagesets, and controller status.

The document also outlines important precautions related to electrostatic discharge, VHDCI cables, and local-connection port usage. It focuses exclusively on CLI operations, directing users to other related publications for detailed operating environment or hardware information.
