An FC switch, iMC_DATA 4500, is connected to the OceanStor S2600 by using optical fibers. The S2600 detects the data transfer rate of the FC switch and automatically adjusts its own rate to 2 Gbit/s. However, the FC switch fails to discover the S2600 and displays NOLIGHT. The default port property of the FC switch is F_PORT.
Change the property of the port on the iMC_DATA 4500 switch that connects to the S2600 from F_PORT to Fx_PORT. The switch discovers the S2600 successfully.
The S2600 is compatible only with the Fx_PORT port of the iMC_DATA 4500 switch.
The iMC_DATA 4500 switch employs its F_PORT port to connect to the host and Fx_PORT port to connect to the storage array. Learn about the setting requirements of the switch before configuring it.
