A–TroubleshootingTroubleshooting with a Diagnostic Port (D_Port)102 BK3254601-00 CFigure A-2. Fibre Channel Troubleshooting Diagram (2 of 2)Troubleshooting with a Diagnostic Port (D_Port)Use the D_Port (diagnostic port) feature on the QLogic 2700 Series Adapters toidentify and isolate link failures resulting from faulty modules (link, cable, or SFP)by running diagnostics over a Fibre Channel link.The D_Port feature is supported on Windows, Linux, and ESXi.D_Port can be run only in dynamic mode; it does not support static mode.D_Port requires a Fibre Channel Adapter that is linked to a Brocade FibreChannel 16G or 32G switch, the supported Brocade 16G or 32G Fibre Channelswitch firmware, and a Brocade Fibre Channel switch feature license (FabricVision™).Configure the diagnostic D_Port on the Brocade switch to dynamically allow a portto enter D_Port mode when a D_Port is configured on the switch end, and thenreturn to operational mode when the test is completed. Also configure the switchto start and stop the diagnostic test on the adapter port. See the Brocade switchdocumentation for details.NoYesYesNoNoYes3Adapter can loginto fabric andname server?Verify that cable is connectedand link lights are litCable isconnected andlink lights lit?TroubleshootphysicalconnecƟonAre opƟcsQLogic?Fibre Channelswitch set forauto-negoƟaƟon?ContactTechnicalSupport2YesNoReplace opƟcs withQLogic opƟcs andreturn to “Start”Check auto-negoƟaƟonon Fibre ChannelCoŶĮgureFibre Channelswitch for auto-negoƟaƟon andreturn to “Start”
