Peripherals and Fault Tolerant Hardware

1-2 Peripherals Configuration (R1001H) HP-UX version 11.00.01

Keep this manual, the online man pages, and any other manuals that were shipped

with your Continuum system available for reference when installing and

configuring peripheral devices.

Commands such as mksf, insf, and ioscan, as well as the Stratus value-added

ftsmaint command, make it unnecessary to manipulate the device special minor

number literally. The Stratus-developed utilities for the HP-UX operating system

provide the ftsmaint command, which provides similar functionality to the

ioscan command, but with added capabilities for administration of Stratus fault

tolerant hardware.

NOTE

Configuring a peripheral device requires that you operate with root

privileges. Exercise caution when acting as super-user.

Peripherals and Fault Tolerant Hardware

Continuum systems employ fault tolerant hardware and hot-plugging features

that simplify your tasks in configuring Continuum systems for peripheral support.

See the HP-UX Operating System: Fault Tolerant System Administration (R1004H) for

information about fault tolerant features. See the hardware documentation for

information about installing and maintaining Continuum system components.

Continuum system components are identified by hardware paths. Hardware paths

specify the addresses of the hardware components leading to specific devices.

Hardware paths consist of a numerical string of hardware addresses, notated

sequentially from the bus address to the device address. Typically, the initial

number is appended by a slash (/) to represent a bus converter or adapter and

subsequent numbers are separated by a dot (.). In order to understand how to

configure Continuum systems for peripherals, you need to know how hardware

paths map to the physical and logical hardware components. See the

“Administering Fault Tolerant Hardware” chapter in the HP-UX Operating System:

Fault Tolerant System Administration (R1004H) for information about how to

determine hardware paths.
