Troubleshooting by symptom

Use the troubleshooting tables to find solutions to problems that have identifiable symptoms.
If you cannot find a solution to the problem in these tables, see Appendix C "DSA diagnostic test results"
on page 549 for information about testing the server and "Running DSA Preboot diagnostic programs" on
page 57 for additional information about running DSA Preboot program. For additional information to help
you solve problems, see "Start here" on page 45.
If you have just added new software or a new optional device and the server is not working, complete the
following steps before you use the troubleshooting tables:
Step 1. Check the system-error LED on the operator information panel; if it is lit, check the light path
diagnostics LEDs (see "Light path diagnostics" on page ).
Step 2. Remove the software or device that you just added.
Step 3. Run IBM Dynamic System Analysis (DSA) to determine whether the server is running correctly (for
information about using DSA, see "Running DSA Preboot diagnostic programs" on page 57).
Step 4. Reinstall the new software or new device.
