Chapter 16 Troubleshooting FICON FICON Overview Send documentation comments to [email protected] Note You can configure port numbers even when no module is installed in the slot. FICON Configuration Files You can save up to 16 FICON configuration files on each FICON-enabled VSAN (in persistent storage). The file format is proprietary to IBM. These files can be read and written by IBM hosts using the in-band CUP protocol. Additionally, you can use the Cisco MDS CLI or Fabric Manager applications to modify these FICON configuration files. When you enable the FICON feature in a VSAN, the switches always use the startup FICON configuration file, called IPL. This file is created with a default configuration immediately after FICON is enabled in a VSAN. Multiple FICON configuration files with the same name can exist in the same switch, provided they reside in different VSANs. For example, you can create a configuration file named XYZ in both VSAN 1 and VSAN 3. Caution When FICON is disabled on a VSAN, all FICON configuration files are irretrievably lost. FICON configuration files contain the following configuration options for each implemented port address: • Block • Prohibit mask • Port address name Tip You cannot prohibit a PortChannel or an FCIP interface. Note If an interface is already configured in E or TE mode and you try to prohibit that port, your prohibit configuration is rejected. Similarly, if a port is not up and you prohibit that port, the port is not allowed to come up in E mode nor in TE mode. Note You can not directly assign a FICON port number to an interface. You assign a range of port numbers to the module. OL-9285-05 Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x 16-5
