FICON Configuration Files

Accessing 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 any other permitted user.

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 MDS SAN-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 the file and obtain the file key. A new file key is used by the locking mechanism for

each lock request. The key is discarded when the lock timeout of 15 seconds expires. The lock timeout

value cannot be changed.

If a specified file does not exist, it is created. Up to 16 files can be saved. Each file name is restricted to

eight alphanumeric characters.

Refresh Note” section on page 22-14.

The Cisco MDS SAN-OS software maintains different configuration files to support a FICON network.

These configuration files can be are saved using the copy running-config startup-config command, or

using Device Manager. FICON configuration files do not contain the following information that is

normally saved with the running configuration:

Refresh Note, page 22-14 for more information.

•Port number to port address mapping

•PortChannel to port number mapping

•Port swap occurrences

•FICON enabled VSANs

FICON configuration files are independent of these parameters. Instead, this information is stored in

persistent storage as they can be modified independent of the startup configuration.

The configuration file submode allows you to create and edit FICON configuration files. If a specified

file does not exist, it is created. Up to 16 files can be saved. Each file name is restricted to eight

alphanumeric characters.
