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.
When FICON is disabled on a VSAN, all FICON configuration files are irretrievably lost.
Caution
FICON configuration files contain the following configuration options for each implemented port
address:
