Chapter 7. Solving problems

This chapter provides basic troubleshooting information to help you solve some
problems that might occur while you are setting up the switch. For more detailed
information about troubleshooting the switch, see the applicable command-line
interface guide and the IBM Flex System FC3171 8 Gb SAN Switch and Pass-thru Event
Message Guide at
http://publib.boulder.ibm.com/infocenter/flexsys/information/index.jsp.
If you cannot locate and correct a problem by using the information in this section,
see Appendix A, "Getting help and technical assistance" on page 41.

Running POST

To ensure that it is fully operational, the switch processes a series of tests during
power-up or a restart (power-on self-test, or POST). These tests take approximately
90 seconds to complete. The Chassis Management Module reads the test results and
displays them for you. The green OK LED is lit at startup; then, POST proceeds and
continues until all of the required tests are completed. If the switch fails POST, the
amber switch Fault LED and the system-error LED on the IBM Flex System chassis
are lit. An event is stored in the event log in the system status panel of the Chassis
Management Module. The specific failure is displayed on the system status switch
panel of the Chassis Management Module.
Note: For the locations and descriptions of the switch LEDs, see Chapter 3,
"Information panel LEDs and external Fibre Channel ports" on page 19.

POST errors

There are two types of errors: noncritical and critical. A noncritical error applies to
one port, and the switch is operational. You can continue to operate the switch;
however, you must replace it as soon as possible. When a critical error occurs, the
switch does not operate. To view POST results, complete the following steps:
1. Log on to the Chassis Management Module as described in the IBM Flex System
2. After POST is completed, the Chassis Management Module displays the results.
