For HP Internal Use Only
Soft Errors
Soft errors are intermittent failures or failures that occur while the operating system is
running. Here are the basic steps in troubleshooting soft failures.
• Determine the environment.
• Check the error logs.
• Run diagnostics.
• Take appropriate action.
You must determine the environment. This means observing the front panel LEDs and any
console messages. You should also check all error logs in the system and peripheral devices, if
appropriate.
If needed, there are both offline and online diagnostics, as well as a system exerciser, that you
can use to troubleshoot the failure. Once you determine the cause of the failure, you can act
accordingly.
Diagnostic Tools
Online Diagnostics
The online diagnostics require a user license and have password protection against
unauthorized use. When you purchase a support license, you will get a password.
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 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.
