Troubleshooting FICON CUP 5 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, 5000, 7500 switches and the Brocade 48000 director 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 64, 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 64. • 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 director 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 FICON NPIV You should capture all pertinent data from the "General information to gather for all cases" on page 64 and "Gathering additional information" on page 66. NPIV licenses must be installed on v5.0.x. There is no license requirement for Fabric OS v5.1.0 and later. FICON Administrator's Guide 67 53-1001771-01

•
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, 5000, 7500 switches and
the Brocade 48000 director 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 64, 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 64.
•
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 director 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 FICON NPIV

“General information to gather for all cases”
on
page 64 and
“Gathering additional information”
on page 66.
NPIV licenses must be installed on v5.0.x. There is no license requirement for Fabric OS v5.1.0 and
later.
