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 to operate on these FICON configuration files.
Note
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 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 as soon as FICON is enabled in a VSAN.
Caution
When FICON is disabled on a VSAN, all the FICON configuration files are irretrievably lost.
FICON configuration files contain the following configuration for each implemented port address:
• Block
• Prohibit mask
• Port address name
Note
Normal configuration files used by Cisco MDS switches include FICON-enabled attributes for a VSAN, port
number mapping for PortChannels and FCIP interfaces, port number to port address mapping, port and trunk
allowed VSAN configuration for ports, in-order guarantee, static domain ID configuration, and fabric binding
configuration.
Refer to the Cisco MDS 9000 Family NX-OS Fundamentals Configuration Guide for details on the normal
configuration files used by Cisco MDS switches.

About FICON Configuration Files

Only one user can access the configuration file at any given time:
• If this file is being accessed by user 1, user 2 cannot access this file.
• If user 2 does attempt to access this file, an error is issued to user 2.
• If user 1 is inactive for more than 15 seconds, the file is automatically closed and available for use by
FICON configuration files can be accessed by any host, SNMP, or CLI user who is permitted to access the
switch. The locking mechanism in the Cisco NX-OS software restricts access to one user at a time per file.
This lock applies to newly created files and previously saved files. Before accessing any file, you must lock
any other permitted user.
