The primary purpose of this paper is to help you plan how to reconfigure
a Superdome complex, though you may also find it useful for mapping
out a Superdome you intend to order.
The heart of the document is the section “Rules and Guidelines for
Configuring a Complex” on page 323, but if you are unfamiliar with the
Superdome architecture, start with the “Building Blocks and Definitions”
on page 286.
There are two ways to reconfigure a Superdome:
• Physically move components such as cells and I/O chassis; or
• Logically reassign cells from one partition to another.
As a customer, you must not make changes of the first type yourself: a
Hewlett-Packard Customer Engineer or Service Engineer must be the
person to move major components such as cells, I/O chassis and cabinets;
that is, anything larger than an I/O card. Use this paper to help you plan
such changes, but don’t attempt to carry them out yourself.
But you can make changes of the second type, reassigning cells from one
partition to another, or assigning unassigned cells. Such changes can
affect performance and high-availability substantially, so it is important
that you read the “Rules and Guidelines for Configuring a Complex” on
page 323 carefully before proceeding. Then use chapter 4 of the manual
Managing Superdome Complexes to guide you through the necessary
tasks.
