Appendix C. Diagnostics and troubleshooting
For information about troubleshooting the entire fabric, refer to the Fabric OS
Administrator's Guide .
The SAN768B-2 includes a number of diagnostic tools to assist with
troubleshooting, including LEDs on the hardware, commands that display current
status, diagnostic tests for hardware and software, and error messages. In addition,
a number of managing and monitoring features are available, such as Fabric
Manager, Web Tools, Fabric Watch, and Advanced Performance Monitoring.
If the SAN768B-2 does not operate as expected, the following steps can be taken to
diagnose the problem:
v
Check the LEDs and refer to the LED tables (see Chapter 4, “Monitoring system
components,” on page 53) for interpretation and recommended actions.
v
Review the results of the last POST run by the SAN768B-2 (see “Interpreting
POST and boot results” on page 160).
v Review the error logs (refer to the Fabric OS Troubleshooting and Diagnostics Guide
for more information).
v
Review RASlog entries.
v
Enter the
sensorShow
command to determine the status of the hardware
components.
v
Run diagnostic tests (see “Diagnostics” on page 161).
v
Reboot the SAN768B-2 or power the entire chassis off (“Powering off the
SAN768B-2” on page 51) and then back on (“Providing power to the
SAN768B-2” on page 37).
If the problem is still unresolved after these steps, contact IBM support. The

Obtaining chassis and component status
The CLI commands listed in Table 29 provide status and environmental
information about the chassis and its components. These commands provide
information only, and they do not interrupt traffic flow. For more information
about these commands, refer to the
