Chapter 16 Troubleshooting FICON
Initial Troubleshooting Checklist

• Choose Fabricxx > VSANyy > FICON in Fabric Manager to view the FICON configuration.
• Choose Fabricxx > VSANyy > Fabric Binding in Fabric Manager to view the fabric binding

Director History to get a history of changes on this FICON VSAN.

ISL configuration for FICON load balancing.

FICON, and click Apply to set the Device Manager display to use FICON port numbers.
Common Troubleshooting Commands in the CLI
Use the following CLI commands to troubleshoot FICON issues:
• show ficon
• show ficon vsan vsan-id file ficon-file-name
• show ficon vsan vsan-id portaddress
• show ficon vsan vsan-id director-history
• show fabric-binding status
• show fabric-binding database
• show fabric-binding violations
• show in-order-guarantee
Port Swapping
The FICON port swapping feature is only provided for maintenance purposes.
Follow these guidelines when using the FICON port swapping feature:
• Port swapping is not supported for logical ports (PortChannels, FCIP links).
• Port swapping is not supported between physical ports that are part of a PortChannel.
• If the two ports involved in a port swap have incompatible configuration options, the port swap is
rejected with an appropriate reason code. For example, if a port with BB_credits as 25 is being
swapped with an OSM port for which a maximum of 12 BB_credits is allowed (not a configurable
parameter), the port swapping operation is rejected.
