3-30 Troubleshooting
To access the diagnostics, type SYSDIAG at the operating system prompt. At the DUI prompt, type list to
display a list of the online diagnostics supported. If you type list long you will get a detailed listing of the
available diagnostics with information about the specific devices tested by the diagnostic. Help is available
for each one. You can find a list of available diagnostics in Chapter 5, Diagnostics. You can find detailed
information about the online diagnostics in the Diagnostic Manual Set.
System Log File Procedure
One of the online diagnostics available is LOGTOOL. You can use logtool to check the system logs. As
with all the online diagnostics, only licensed users can use logtool.
Perform the following procedure to display the system logs. Enter the commands that are underlined.
System Exerciser (HP 3000 only)
Another tool that you can use for troubleshooting is the System Exerciser, or SX. The system exerciser is
loaded into the TELESUP account as part of the fundamental operating system.
Other exercisers are available in a collection of tools called the Support Tool Manager. You can find out
more information by referring to the Hardware Online Tools User’s Guide.
HP-UX 10.2x or later
Refer to Chapter 5, Diagnostics.
Offline Diagnostics
There are some times when you will want to use offline diagnostics instead of online diagnostics:
• If the operating system will not run.
• You don't want to jeopardize the integrity of the operating system.
• You suspect some potential problem with the operating system.
The offline diagnostics for this family of systems and future systems are contained in a shell called ODE,
which stands for Offline Diagnostic Environment. ODE is available on the Support Media. One program,
Mapper, is available on disk. To access ODE, you will need to boot to ISL and interact with IPL.
