This chapter discusses troubleshooting, diagnostic testing, and error messages, including the following sections: Diagnostic overview Status and activity indicators Diagnostic tests Refer to the Dell PowerVault Systems Storage Area Network (SAN) Installation and Troubleshooting Guide for further troubleshooting information. The switch is designed for maintenance-free operation. When there is a suspected failure, the switch has self-diagnostic capabilities to aid in isolating any equipment or fabric failures. The switch supports power-on self-tests (POSTs) and diagnostic tests. The diagnostic tests determine the switch's status and isolate problems. Telnet commands are used to determine the switch's status, error conditions, and switch operating statistics. support.dell.com Error messages are available both by way of the switch's front panel LCD display and through a Telnet session. These messages are also stored in the system log and are displayed when the errShow command is executed. If you run the portStatsShow or the diagShow command prior to running a test on the switch, errors may appear as a result of the normal synchronization process. These errors should be addressed if the number of errors found increases when running the portStatsShow command again. Where multiple probable cause and corrective actions are listed following an error message, they are listed with the most probable first and the least probable last. If any port fails during a diagnostic test, it is marked ignored (not tried) until the system is rebooted. in the status display and is Troubleshooting 5-1
