Upgrading the RAID Array 410 Controller

to RAID Array 450 for IBM AIX

This chapter describes procedures to upgrade the RAID Array 410 controller and cache modules for the
IBM AIX platform.

This chapter describes how to upgrade the RAID Array 410 controller and cache modules
in both single controller and dual-redundant controller configurations. Included in this
upgrade are the following:

• 

Controller module

• 

Cache module

• 

External Cache Battery (ECB) and cable

•

3.1

Upgrade Road Map

Replacing a controller module involves several considerations:

• 

Ensuring that your system meets the upgrade prerequisites described in Section 3.1.1
below

• 

Preparing your host system for the upgrade

• 

Recording the RAID subsystem configuration

• 

Replacing the controller(s) and cache module(s)

• 

Restoring the RAID subsystem configuration

• 

Upgrading the host system configuration

3.1.1  Upgrade Prerequisites and Considerations

Before upgrading the RAID Array 410 controller(s) and cache module(s), please review
the following:

• 

The RAID Array 450 is supported on AIX 4.1.4 and 4.2 only. If necessary, upgrade
your operating system before the RAID Array 450 controller and cache module
upgrade is attempted.
