Running ODE-Based Diagnostics
Running ODE-Based Diagnostics
The Offline Diagnostic Environment (ODE) consists of diagnostic modules for testing and
verifying system operation. ODE provides all the necessary functions for the user to load
specified tests and interact with those tests.
ODE is an ISL utility. To boot ODE:
1. Invoke the ISL environment from the system disk or CD-ROM.
2. Type ode
[Enter] after the ISL> prompt to invoke ODE from the LIF directory on the
system disk. The prompt changes to ODE>.
Not all of the test modules are available on all systems. To see what test modules are
available to run on this system, type ls at the ODE> prompt. The available modules include
the following:
• wdiag – tests and verifies the basic functionality of the PA-8500 chip. This tool tests the
CPU, cache, TLB and floating point functions.
• memtest – tests and verifies the memory arrays. If an error is detected, the diagnostic
reports the memory card and its slot number that needs replacement. It also, provides a
map of the memory configuration so that the user can identify the types of memory and
its slot location.
• mapper – identifies the configuration of HPPA systems. It displays path, identification,
and revision information of I/O components, configuration of memory controllers,
processors, co-processors, cache, and TLB, as well as processor board component
revisions and values of various HPPA system identifiers, revisions and capabilities.
• astrodiag – tests and verifies the basic functionality of the Astro memory/IO controller
chip.
• siodiag – tests and verifies the functionality of the super IO multifunction IO chip,
including serial, parallel, USB, etc.
For further information on the various ODE commands and a complete listing of the
command set, type help
[Enter]attheODE> prompt or at the prompt of one of the test
modules.
