Operating the SAN Director 2/128 Diagnostics and Troubleshooting Overview For information about troubleshooting the entire fabric, refer to the HP StorageWorks Fabric OS 4.2.x Procedures User Guide. The SAN Director 2/128 includes a number of diagnostic aids 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 optional management tools are available, such as Fabric Manager, Fabric Watch, and Advanced Performance Monitoring. If the SAN Director 2/128 does not operate as expected, the following steps can be taken to diagnose the problem: ■ Check the LEDs and refer to the LED tables (see "Interpreting LED Activity" on page 82) for recommended actions. ■ Review the results of the last POST run by the SAN Director 2/128 (see "Interpreting POST and Boot Results" on page 100). ■ Review the error logs (refer to the HP StorageWorks Diagnostic and System Error Messages 4.2.x Reference Guide for more information). ■ Enter the sensorshow command to determine the status of the hardware components. ■ Run diagnostic tests (see "Diagnostics" on page 102). ■ Reboot the switch or power the entire chassis off/on. If the problem is still unresolved after these steps, contact your support provider. The information required by your support provider in order to provide assistance is listed under "Getting Help" on page 14. 96 SAN Director 2/128 Installation Guide
