Diagnostic tools overview
Diagnostic tools overview
Server problems can be caused by the hardware, the software, or a
user error. An example of a user error is pressing the wrong key on
the keyboard.
You can check the hardware by using the diagnostic test programs
and the information in this chapter.
Notes:
1. Some hardware and software errors are caused by configuration
conflicts. For information on handling these situations, see
“Resolving configuration conflicts” on page 57.
2. When running the diagnostic test programs, a single problem
can cause several error messages to occur. When this happens,
work to correct the cause of the first error message. After the
cause is corrected, the other error messages probably will not
occur the next time that you run the tests.
If the hardware is OK and you have not made an error, you might
have a software problem. If you suspect that you have a software
problem, refer to the information that comes with that software
package.
