Installing an HSZ80 Array Controller

This document provides step-by-step procedures for the replacement and installation of an HSZ80 array controller. It covers two primary configuration scenarios:

• Dual-Redundant Controller Configuration: Detailed steps are provided for both removing a controller (using the FRUTIL utility to quiesce device ports and safely transition the system) and installing a new controller (incorporating configuration synchronization and purging of old configuration data).
• Single Controller Configuration: Procedures for taking the host offline, shutting down the controller, and replacing the hardware, including post-installation tasks such as patching and logical unit re-mounting.

The guide emphasizes safety precautions, specifically regarding electrostatic discharge (ESD) protection and adherence to specific terminal commands to prevent data loss.
