Configuring switched point-to-point FICON

This section provides detailed steps and commands to configure a switch for point-to-point FICON

operation. The following steps assume that you have used your hardware reference manual to

perform the initial setup of the switch and have performed all the steps from “Preparing a switch

for FICON” on page 19.

For basic steps and commands in a checklist format to quickly configure a switch for fabric and

possible FICON operation, refer to Appendix B, “Basic Switch Configuration”, then return to this

chapter for detailed FICON configuration procedures.

Use the worksheet in Appendix D, “Configuration Information Record,” to record your configuration

information.

Refer to “FICON commands” on page 12 for a list of FICON-related Fabric OS commands.

CAUTION

Configuring the switch for FICON is a disruptive process. The switch must be disabled to configure

switch parameters.

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

2. Enter the switchDisable command. You will need to disable the switch to access all the switch

parameters.

3. Configure the switch and chassis name, if applicable.

4. Set the routing policy to port-based routing (aptPolicy 1) by entering the aptPolicy command.

The recommended best practice is to use port-based routing.

In addition, if FICON Emulation features (IBM z/OS Global Mirror or Tape Pipelining) are

enabled on an FCIP Tunnel in the switch, aptPolicy 1 must also be used.

5. Configure Dynamic Load Sharing.

The recommended best practice is to enable Dynamic Load Sharing (DLS); however, DLS is

only supported when Lossless is enabled.

• To enable Lossless with DLS, use the dlsSet --enable –lossless command.

• If Lossless will not be used, use the dlsReset command.

NOTE

If Lossless with Lossless DLS is not enabled, the routing policy must be port-based routing

(aptPolicy 1).

6. Set In-Order Delivery using the iodSet command.
