StorageWorks FDDI Server Upgrade Manual

This manual provides detailed procedures for upgrading various StorageWorks Fiber Distributed Data Interface (FDDI) Server models (HS1xx and HS2xx series) to newer HS2xx FDDI Servers. It covers upgrades from an SW800 cabinet to HS211, HS111 to HS211, HS121 to HS221, HS211 to HS221, HS121 to HS241, HS221 to HS241, and installing the HS280 expansion cabinet for HS241.

The guide outlines pre-installation considerations, environmental specifications, and tools needed. Key steps involve physical hardware installation, such as installing server processors, device channel processors (HS1CP) with write-back cache modules, BA350-M shelves, and internal bus cables. It also details crucial software configuration tasks, including upgrading console code and the OpenVMS Alpha operating system, setting initial parameters for device channel processors, installing write-back cache license keys, configuring storage devices (stripesets, RAIDsets, sparesets, passthrough containers) using the CFMENU utility, and running the EISA Configuration Utility. The document emphasizes verifying installations and integrating the upgraded servers into a VMScluster environment, including considerations for quorum schemes and Volume Shadowing interoperability. Finally, it touches upon ongoing system software maintenance and optimizing I/O load balance for dual-processor servers.
