This chapter discusses removing and replacing components, and downloading

firmware. It ends with a summary on configuring a peripheral.

Removing and Replacing Components

The HP-UX operating system adds components to the system structure at boot time

by inventorying the existing Continuum hardware components and configuring the

system accordingly. Once the system is running, you can use the ftsmaint

command to remove and replace Continuum hardware components or the

addhardware command to add new hardware to a running system.

When replacing Customer Replacable Units (CRUs), the following restrictions apply:

■ When removing a hardware component, you must replace it with another

component of the same type.

■ The addhardware command allows you to add a new hardware component to

a running system without needing to manually step through remaking the kernel

or rebooting the system. See the HP-UX Operating System: Fault Tolerant System

Administration (R1004H) and the mk_kernel(1M), flifcp(1M), and flashdd(1M) man

pages.

■ To prevent unpredictable system behavior, issue an ftsmaint disable and

following enable command to disconnect it from its software link before

removing a hardware component.

A newly replaced CRU undergoes diagnostic self-test. If it passes diagnostics and

satisfies configuration constraints, the resources contained in that component are

made available to the system.
