Troubleshooting FICON CUP

Also refer to the most recent version of the Fabric OS Release Notes for notes on FICON setup

and configuration.

• Is this a switched point-to-point or cascaded environment?

• Is the FICON group enabled for supportshow?

Check at the top of the supportshow. If not, use supportShowCfgEnable ficon and re-run the

test that was failing.

NOTE

If this setting is not set to port-based routing on the Brocade 4100, 4900, or 5000 switches and the

Brocade 48000 switch in a FICON fabric, you will experience excessive interface control checks

(IFCCs) on the mainframe whenever a blade or CP is hot-plugged or unplugged.

Troubleshooting FICON CUP

In addition to the information you would collect for your support provider mentioned

“Troubleshooting FICON” on page 76, also gather the following information which is specific to

FICON CUP:

• Capture all data from the “General information to gather for all cases” on page 76.

• Verify the FICON CUP license is installed.

• Check the state of the CUP port by running the ficonCupShow fmsmode command. If it is

disabled, type the ficonCupSet fmsmode enable command to enable it. If this is on a directory,

enter the haFailover command to ensure both CPs are set correctly.

• Verify that the switch has a Fabric OS v6.1.0 or later.

• Ensure no device is plugged into port 254 on the Brocade 48000 or Brocade DCX

enterprise-class platform.

• Verify with the systems programmer that the CUP ports are defined properly.

FICON ports are defined as part of the sysgen process. The z/OS systems programmer can

verify if the CUP ports are defined properly.

• Verify the ports 254 and 255 display the Disabled (FMS Mode) by entering the switchShow

command. If not, enter the portDisable command on the appropriate models for the related

ports:

- On a Brocade 48000, disable 10/30 and 10/31.

- On a Brocade DCX Backbone, disable 12/30 and 12/31.

Troubleshooting NPIV

You should capture all pertinent data from the “General information to gather for all cases” on

page 76 and “Gathering additional information” on page 78.

NPIV licenses must be installed on Fabric OS v5.0.x. There is no license requirement for Fabric OS

v5.1.0 and later.
