Cascaded FICON and 2-byte addressing considerations The following are considerations when installing a switch in a FICON environment where 2-byte addressing is used. Two-byte addressing is always used in cascaded environments but may be used in single switch fabrics as well. Making changes to your switch or director may require scheduled downtime. • All fabric operating parameters, such as time-out values, must be the same. If you have not made any changes outside the scope of this document there is nothing additional to consider regarding these parameters. • The domain IDs of all switches must be unique and insistent. • Although not required, it will be easier to configure the security policies if the zoning matches. Configuration, connecting the ISLs, and ensuring that the switches and directors have merged into a fabric, will also make the process of setting the security attributes much easier. Configuring switched point-to-point FICON Use the worksheet in Appendix A, "Configuration Information Record," to record your configuration information. These steps assume 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 15. 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. Take the appropriate action based on whether you have both B- and M-series switches in your fabric: • If you do not have both series, proceed to step 5. • If you have both series, verify that the Fabric Mode is set to 2 on the supported platforms.

Cascaded FICON and 2-byte addressing considerations
The following are considerations when installing a switch in a FICON environment where 2-byte
addressing is used. Two-byte addressing is always used in cascaded environments but may be used
in single switch fabrics as well. Making changes to your switch or director may require scheduled
downtime.
•
All fabric operating parameters, such as time-out values, must be the same. If you have not
made any changes outside the scope of this document there is nothing additional to consider
regarding these parameters.
•
The domain IDs of all switches must be unique and insistent.
•
Although not required, it will be easier to configure the security policies if the zoning matches.
Configuration, connecting the ISLs, and ensuring that the switches and directors have merged
into a fabric, will also make the process of setting the security attributes much easier.
Configuring switched point-to-point FICON
Use the worksheet in
Appendix A, “Configuration Information Record,”
to record your configuration
information. These steps assume 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 15.
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.
Take the appropriate action based on whether you have both B- and M-series switches in your
fabric:
•
If you do not have both series, proceed to
step 5
.
•
If you have both series, verify that the Fabric Mode is set to 2 on the supported platforms.
