Hardware Diagnostic Software
The purpose of hardware diagnostic software is to provide tools for checking hardware
problems. By design, diagnostic software executes simple tests of each hardware component.
Usually, such tests assure the hardware is not the source of server problems. This allows the
user to eliminate hardware as the cause of the problem and to focus on operating system
configuration parameters, network connections, and application software configuration
parameters as the source of the problem.
If hardware problems are confirmed, the diagnostic software program can sometimes detect
and diagnose the system or specific server component causing the problem. In addition,
hardware diagnostic software can capture information that allows support personnel to
quickly assess the condition of the server. In order to be effective, diagnostic software tools
must be used in the context of a wider troubleshooting procedure.
