Modifying FICON emulation

portcfg fciptunnel 23 modify --ficon-tape-write 1 --ficon-tape-read 1

portcfg fciptunnel 23 modify --ficon-print 1

Note that the preceding commands assume that an FCIP tunnel was a enabled for FICON operation

by using the --ficon option. Following are two examples:

• To create a empty tunnel as a FICON FCIP tunnel, use the following command:

portcfg fciptunnel 1/17 create -F -c 1

• To modify a tunnel to be FICON enabled and with hardware compression enabled, use the

following command:

portcfg fciptunnel 1/17 modify -c 1 -F 1

Displaying FICON emulation configuration values

For a Brocade 7800 or FX8-24 blade, use the portShow fciptunnel command to display FICON

configuration values. Command output shows which emulation features are enabled or disabled

and displays related emulation parameters for each tunnel.

For more information, refer to “Displaying FICON emulation performance statistics” on page 55.

Modifying FICON emulation

FICON emulation may be enabled on a per FCIP tunnel basis. For the Brocade 7800 switch and

FX8-24 blade, use the portCfg fciptunnel command to make modifications to the feature.

For details on command usage, refer to the Fabric OS Command Reference Manual.

ATTENTION

You must bring the FCIP tunnel down in order to make changes. This process is disruptive to all traf fic

on the tunnel.

1. Connect to the switches at both ends of the FCIP tunnel and log in using an account assigned

to the admin role.

2. Disable the FCIP tunnel at both ends where the FICON emulation feature is enabled.

3. Use the portCfg fciptunnel modify command for the Brocade 7800 switch or FX8-24 blade.

4. Make matching FICON emulation changes to both ends of the tunnel.

5. Enable the FCIP tunnel.

Displaying FICON emulation performance statistics

You can use the portShow command to view the performance statistics and monitor the behavior

of FICON emulation. You do not need to disable any feature to display statistics.

1. Connect to the switch and log in using an account assigned to the admin role.

2. Use the portShow xtun command to display the statistics for the 7800 switch or FX8-24 blade.
