Introduction
Troubleshooting AH303A Host Bus Adapter problems can be difficult, because a variety of
hardware and software components can be involved. A systematic approach to troubleshooting
helps isolate the problem. If you cannot solve the problem, contact your HP representative.
NOTE: Before using these troubleshooting steps, you must install, configure, and verify the
AH303A Host Bus Adapter hardware and software on the host and on any devices.
Event Monitoring Service
Event Monitoring Service (EMS) notifies you when an event occurs on the system.
A hardware event monitor monitors hardware for unusual behavior (an event) and sends a
message to EMS, which notifies you of the event and provides suggestions for correcting the
problem.
For information about how hardware monitors work, see:

Offline Diagnostics Environment
The HP Offline Diagnostics Environment (ODE) is an offline support tool for troubleshooting
systems that are running without an operating system or for systems that cannot be tested using
online tools. The offline environment is also useful for testing a system before it boots.
ODE provides a user-friendly interface for diagnostics and utilities developed to run in this
environment.
ODE has a distributed architecture consisting of several modules. Each module has a specific
function and uses well-defined protocols to communicate with the other modules.
You can use ODE with a command-line or menu-driven interface. The command-line interface
enables you to select specific tests and utilities to perform on a specific hardware module. The
menu-driven interface enables you to specify the hardware module to be tested, then it selects
and performs the necessary tests.
The Offline Diagnostic Environment consists of:
• A Test Controller, which acts as the user interface and launches the execution of the Test
Modules.
• Test Modules, which consist of diagnostic or utility programs that execute in ODE. These
modules exercise or diagnose user specified hardware units.
• A System Library (SysLib), which consists of a set of common routines for use by the Test
Controller and Test Modules. These routines perform I/O, string parsing, and system control.
