Identifying media-related issues This section provides procedures that help pinpoint any media-related issues in the fabric. The tests listed in Table 60 are a combination of structural and functional tests that can be used to provide an overview of the hardware components and help identify media-related issues. • Structural tests perform basic testing of the switch circuit. If a structural test fails, replace the main board or port blade. • Functional tests verify the intended operational behavior of the switch by virtue of running frames through ports or bypass circuitry. Table 60 Component test descriptions Test Name Operands Checks crossporttest fporttest loopporttest spinfab [-nframes count] [-lb_mode mode][-spd_mode mode] [-gbic_mode mode] [-norestore mode] [-ports itemlist] [-nframes count] [-ports itemlist] [-seed payload_pattern] [-width pattern_width] [-size pattern_size] [-nframes count] [-ports itemlist][-seed payload_pattern] [-width pattern_width] [ -nmegs count ] [ -ports itemlist ] [ -setfail mode ] Functional test of port external transmit and receive path. The crossport is set to loopback using an external cable by default. However, this command can be used to check internal components by setting the lb operand to 5. Tests component to/from and HBA. Used to test online F_Port devices, N_Port devices, SFPs, and GBICs. Only tests components attached to a switch that are on a FC-AL. Tests switch-to-switch ISL cabling and trunk group operations. The following procedures are for checking switch-specific components. To test a port's external transmit and receive path 1. Connect to the switch and log in as admin. 2. Connect the port you want to test to any other switch port with the cable you want to test. 3. Enter the crossPortTest command with the following operands (this is a partial list. Refer to the Fabric OS Command Reference Manual for additional command information): • [-nframes count]-Specify the number of frames to send. • [-lb_mode mode]-Select the loopback point for the test. • [-spd_mode mode]-Select the speed mode for the test. • [-ports itemlist]-Specify a list of user ports to test. Example switch:admin> crossporttest Running Cross Port Test .... passed. Fabric OS 5.2.x administrator guide 295
