errors.
FICON troubleshooting
The following section states a possible issue and the possible cause for FICON errors.
Problem Resolution
After upgrading to Management application
12.x from 11.x, unable to discover Fabric OS
devices. Error "4002" displays when trying to
discover Fabric OS devices. The Management application 12.x uses Java 1.7, which disables the use of certificates
with "weak authentication". You must update your Java certificates to resolve the issue.
Problem Resolution
If a switch is replaced by another switch having
the same IP address but a different node WWN
while fabric tracking is on, the Management
application does not update the Product List,
Connectivity Map, or switch properties with the
new node WWN. Choose from one of the following options:
•
Turn fabric tracking off while the switch is replaced. This causes the old switch to be
removed and the new switch added.
•
After the switch is replaced, remove and re-add the fabric in the Discover Setup
dialog box.
Problem Causes
FICON not supported on switch error. FICON Unsupported Configurations:
•
FICON is not supported on base switches.
•
FICON is not supported on a logical switch which has an XISL configured.
•
FICON is not supported if the PID format is 2.
•
FICON is not supported if 10 bit address is enabled on 8-slot Backbone Chassis for
non-default switch.
•
FICON is not supported if any port address is greater than the maximum port number
of the switch.
•
48-port blades are not allowed in the Director Chassis for FICON.
•
FICON is not supported on 48-port blades in the 8-slot Backbone Chassis when
Virtual Fabrics is disabled. However, when Virtual Fabrics is enabled in the Backbone
Chassis, FICON is supported on the 48-port blade as long as the 48-port blade is part
of a logical switch. If the 48-port blade is part of the default switch on the Backbone
Chassis, FICON is not supported.
