The StorageWorks Upgrade Procedures for RAID Array 410 to RAID Array 450
Installation Guide
This guide describes the upgrade procedures required to convert the RAID Array 410
Subsystem to a RAID Array 450 Subsystem.
Intended Audience
This guide is for system administrators and users who need to upgrade a RAID Array
410 Subsystem to a RAID Array 450 Subsystem.
Organization
This guide contains a separate chapter for upgrading the RAID Array 410 Subsystem to
the RAID Array 450 subsystem on six different platforms.
Each chapter provides:
•
A procedure for recording the current configuration.
•
Shutting down the RAID Array 410 Subsystem.
•
Physically removing the 410 controller and cache module(s).
•
Physical installation of the 450 cache module(s), controller(s), and new External Cache
Battery.
•
Verification of system configuration.
•
Procedures for setting the RAID Array 450 controller parameters.

Upgrading the RAID Array 410
to RAID Array 450 for Digital UNIX
This chapter describes procedures to upgrade the controller and cache modules for the Digital UNIX
platform.
This chapter describes how to upgrade the RAID Array 410 controller and cache module
in both single and dual-redundant controller configurations. Included in this upgrade are
the following:
• Controller module
• Cache module
• External cache battery (ECB) and cable
• This document
1.1 Upgrade Road Map
Replacing controller module(s) and cache module(s) involves several considerations:
• Ensuring that your system meets the upgrade prerequisites described in Section 1.1.1
below
• Preparing your host system for the upgrade
• Recording RAID subsystem configuration
• Replacing the controller(s) and cache module(s)
• Restoring the RAID subsystem configuration
• Upgrading the host system configuration
NOTE
You should determine the exact system configuration
that you are servicing (a nonredundant controller or
both dual-redundant controllers) before proceeding to
the following sections, as each procedure varies and
has different consequences.

RAID Array 410 to 450 Upgrade
1–2 EK–SM410–UP. A01
This procedure documents single controller to single controller upgrades and dual-
redundant to dual-redundant controller upgrades only. To upgrade a single controller to a
dual-controller configuration, first perform the single to single upgrade and then add the
second controller using the procedure described in Chapter 1, Paragraph 1.8 of the
Getting Started – RAID Array 450 for Digital UNIX.
1.1.1 Upgrade Prerequisites
Before upgrading the RAID Array 410 controller(s) and cache module(s), please review
the following:
• If necessary, upgrade your operating system before the controller and cache module
upgrade is attempted.
• One platform kit is required for each controller. Among other things, the platform kit
includes the HSOF Version 5.0 Program Card required for controller operation
• Included with the RAID Array 450 Version 5.0 software is the StorageWorks
Command Console (SWCC) Agent.
• The controller (s) and all storagesets must be in normal running condition.
• During this upgrade procedure do not add, remove, or move any devices. Any device
configuration changes can be made after the upgrade is completed and verified.
• After removing the old controller, return the controller and PC card in accordance
with the instructions contained in the customer letter found in the RAID Array 450
platform kit.
1.1.2 Tools Required
You need the following tools to remove or replace the controller module:
• ESD (ElectroStatic Discharge) strap
• Medium blade screwdriver for module replacement
• Small blade screwdriver for trilink and external cache battery cable fasteners

1.1.3 Precautions
In general, you should follow routine ESD protection procedures when handling
controller modules and cache modules and when working around the cabinet and shelf
that houses the modules.
Follow these guidelines to further minimize ESD problems:
• Use ESD wrist straps, antistatic bags, and grounded ESD mats when handling
controllers and cache modules.
• Obtain and wear an ESD wrist strap on your wrist. Make sure the strap fits snugly.
• Attach the lead on the ESD strap to a convenient cabinet grounding point.
• After removing a module from the shelf, place the module into an approved antistatic
bag or onto a grounded antistatic mat.
• Remain grounded while installing a replacement module.
CAUTION
Follow program card guidelines or damage to the
program card and controller software can result.
1.2 Preparing Your Host System
Before starting the upgrade process you will need to prepare your system. This includes
performing a complete system backup, recording the volume group configurations, and
shutting down the system.
1.2.1 Backup Data Files
As a precaution before starting this procedure you should backup the entire system,
especially data stored on the RAID Array.
1.2.2 Shut Down the Host System
Unmount from the host system any units that are accessed through the RAID Array 410
that is about to be upgraded. Follow the proper procedures to shutdown the host system.
1.3 Making a Serial Connection with the RAID Controller
You must make a serial connection to the RAID controller to access the Command Line
Interpreter (CLI). The CLI is the user interface built into the RAID Controller. It
provides a series of commands for you to create a configuration for the subsystem
through the controller’s software.
See the CLI Reference Manual for detailed descriptions of all CLI commands.
You can make a serial connection to the RAID controller from a maintenance terminal.

1.3.1 Connecting the Cable
To connect a maintenance terminal to a RAID controller follow these steps:
1. Locate the connecting cable that came with the RAID subsystem. It has an RJ12
connector (similar to standard telephone plug) on one end and a 9-pin serial
connector on the other end.
2. Plug the serial connector into the 9-pin serial port/com port 1 of the maintenance
terminal. If a 9-pin serial port is not available, use the 9-pin to 25-pin adapter
(P/N: 12-45238-01) supplied with your StorageWorks RAID Array 450 Subsystem.
3. Plug the RJ12 connector from the maintenance terminal into the maintenance port on
the RAID Array 410 controller (see Figure 1–1).
4. Set the terminal communications parameters to:
• 9600 baud
• 8 bits
• 1 stop bit
• No parity

1.3.2 Establishing Connection with a Maintenance Terminal
After connecting the maintenance terminal cable to the controller, press the Enter key.
The CLI prompt appears in the window similar to the following:
swxrc>
1.4 Recording Your Configuration Data
In the following steps, you need to record your configuration for use later in this
procedure.
First, record the controller configuration:
swxrc> show this_controller full
