Performing The Checkout Procedure; Diagnostic Tools - IBM NeXtScale nx360 M4 Installation And Service Manual

Performing the checkout procedure

Use this information to perform the checkout procedure.
To perform the checkout procedure, complete the following steps:
1. Is the server part of a cluster?
2. Complete the following steps:
3. Is there a readable image on the monitor screen?

Diagnostic tools

The section introduces available tools to help you diagnose and solve
hardware-related problems.
v Light path diagnostics
v Event logs
v Integrated management module II
v No: Go to step 2.
v Yes: Shut down all failing servers that are related to the cluster. Go to step 2.
a. Check the power supply LEDs (see "Power-supply LEDs" on page 53).
b. Turn off the server and all external devices.
c. Check all internal and external devices for compatibility at
http://www.ibm.com/systems/info/x86servers/serverproven/compat/us.
d. Check all cables and power cords.
e. Set all display controls to the middle positions.
f. Turn on all external devices.
g. Turn on the server. If the server does not start, see "Troubleshooting by
symptom" on page 62.
h. Check the system-error LED on the operator information panel. If it is lit,
check the light path diagnostics LEDs (see "Compute node controls,
connectors, and LEDs" on page 13).
i. Check for the following results:
v Successful completion of POST (see "POST" on page 58 for more
information)
v Successful completion of startup, which is indicated by a readable display
of the operating-system desktop
v No: Find the failure symptom in "Troubleshooting by symptom" on page 62;
if necessary, see "Solving undetermined problems" on page 78.
v Yes: Run DSA (see "Running DSA Preboot diagnostic programs" on page 60).
– If DSA reports an error, follow the instructions in Appendix C, "DSA
diagnostic test results," on page 321.
– If DSA does not report an error but you still suspect a problem, see
"Solving undetermined problems" on page 78.
Use light path diagnostics to diagnose system errors quickly. See Light path
diagnostics for more information.
The event logs list the error codes and messages that are generated when an
error is detected for the subsystems IMM2, POST, DSA, and the server
baseboard management controller. See "Event logs" on page 55 for more
information.
