DIGITAL StorageWorks HSZ40 Array Controller HSOF 3.1 CLI Reference Manual

This document is the DIGITAL StorageWorks HSZ40 Array Controller HSOF 3.1 CLI Reference Manual, published in March 1997.

It serves as a comprehensive guide for using the Command Line Interpreter (CLI) to manage and configure the HSZ40 Array Controller subsystem.

Key areas covered include:

• Introduction to the CLI: Explains what the CLI is, how to access and exit it (local vs. remote connections), methods for capturing CLI sessions, general rules for entering commands (e.g., case-insensitivity, command abbreviation, editing keys), and the Port-Target-LUN (PTL) addressing system for devices.
• Detailed CLI Commands: The bulk of the manual describes numerous commands for:
  • Configuration: Adding and deleting various storage components like CD-ROMs, individual disks, mirrorsets, passthrough containers (for tape drives), RAIDsets, sparesets, stripesets, and host-addressable units.
  • Partitioning: Creating and destroying partitions on disks or storagesets.
  • System Management: Initializing storage containers, renaming components, setting device characteristics (like data transfer rates), and managing failover policies (including dual-redundant configurations and preferred paths).
  • Monitoring & Information: Commands to display detailed information about controllers, storagesets, devices, and units.
  • Troubleshooting & Diagnostics: Commands to clear various error conditions (e.g., invalid cache, lost data, unknown devices, unwriteable data) and run controller self-tests or other utility programs.
  • Caching: Configuring read cache, write-back cache, cache flush timers, and battery policies for cache.
  • Controller Operations: Commands to restart or shut down the controllers, with specific distinctions between the controller running the CLI session (THIS_CONTROLLER) and its partner (OTHER_CONTROLLER).

The manual provides syntax, parameters, switches, and practical examples for each command, along with important notes and cautions regarding data integrity and system behavior. It also includes a Glossary of relevant terms.
