HP Server Diagtools
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 that 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
subsystem or specific server component causing the problem. In addition, diagnostic tools 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.
Diagtools for HP Servers is a set of offline diagnostic tests, including tests for system and processor
components, memory and storage elements, ports, and input/output devices. Diagtools is supplied on the HP
StartUp CD-ROM.
