Chapter 4 Diagnostics

In order to be effective, diagnostic software tools must be used in the context of a wider troubleshooting
procedure.
DiagTools Capabilities
DiagTools for HP NetServers is a set of off-line 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 .
The user prepares DiagTools software for use by transferring it to diskette. Then the DiagTools diskette is
used to boot the server. A basic suite of tools checks key NetServer components, and a menu of advanced
tests is available for in-depth testing.
DiagTools has the ability to test the following components:
l
system board
l
processors
l
memory modules
l
hard disk drives
l
flexible disk drives
l
keyboards
l
parallel ports
l
CD-ROM drives
l
video monitor
DiagTools is an off-line diagnostic. Off-line diagnostics do not use the main operating system (OS) of the HP
NetServer. The alternate DiagTools OS has far fewer features than the full-fledged OS. Thus, its capabilities
are limited to a set of basic tests and a series of advanced tests. In addition, DiagTools does not use any
tests, which might write over and thus destroy user data. Tests that require user inputs or decisions are left
to the advanced series of tests.
You can use DiagTools to perform the tasks listed below:
• display a high-level inventory of the NetServer under test
•
save and print a detailed inventory of hardware components
• conduct a basic test of components listed in the NetServer inventory
•
display “PASSED” or “FAILED” overall results of basic tests
•
record detailed test results of basic NetServer tests
• display a menu of advanced tests
•
select and run one or a series of advanced tests
•
add the record of results of advanced tests to the record of basic tests
• view a list to locate the meaning of a specific error code
•
view one or more steps to help confirm and isolate error conditions
•
browse the Support Ticket, which contains the detailed inventories and test results
•
add comments to the Support Ticket
