Verifying Attached Devices

Overview

E Verifying Attached Devices

This section discusses using the initial system loader’s ODE utility to verify which devices

are attached and conﬁgured to a HP e3000 computer system.

Overview

SYSGEN provides utilities for listing the conﬁgured paths and associated devices of a

system. It does not, however, provide a utility for listing the devices actually attached to

the system. (A valid conﬁgured path does not require an associated device.) The initial

system loader (ISL) provides the ODE utility for locating the devices attached to a system.

A list of attached peripherals aids the system manager in assessing a system's needs,

deciding where (on which I/O paths) to add or remove peripheral devices, resolving I/O

path conﬂicts (as with SYSGEN and NMMGR), and restoring or copying a system’s

conﬁguration.

Displaying Conﬁgured Devices

ODE is a utility that is located in the ISL boot directory of an HP e3000 computer system. It

can be launched only from ISL, which indicates that the system is down.

When running with default options, ODE running mapper or mapper2 performs the

following operations:

• Displays the current conﬁguration of the processor, including the presence of

coprocessor boards, analyzer cards, memory sizes of cache and translation look-aside

buffer (TLB) cards, the processor model number, and the processor-dependent code

(PDC) ﬁrmware revision.

• Checks all possible I/O paths to determine if a component is present, and identiﬁes

every component (such as a module, bus converter, adapter, device, or unit.)

• Displays a table showing all conﬁgured components.

• Performs self-test and/or loopback tests on all components with self-test and/or

loopback capabilities.

• Does not test any devices (terminals, data communication lines, or other serial devices)

connected to external ports of the terminal multiplexer.

The loopback test performs component-dependent loopback tests where feasible. The

result of this test is reported as pass, fail, unimplemented, or untestable.
