HSZ80 Patch (V83Z-1) for Tru64 Unix SWCC Version 2.2 Agent

This document, labeled as Information Blitz TD 2736-CR, details the release of patch V83Z-1 for the Compaq HSZ80 Storage Controller. The patch introduces a necessary lock mode page, allowing the controller to function correctly with the Tru64 Unix SWCC (StorageWorks Command Console) Version 2.2 Agent in multi-initiator environments.

Without this update, attempting to run multiple instances of the SWCC 2.2 Agent with unsupported controllers may result in serious SCSI-related errors, such as bus resets, data overruns, and reservation conflicts. The document advises using the SWCC Client's 'Update Controller Software' feature to apply the patch rather than manual installation and clarifies that currently, only the HSG80 (V8.5) and HSZ80 (V83Z-1) controllers support this required locking feature.
