280 Administering FICON fabrics
Troubleshooting
The following sources provide useful problem-solving information:
• The standard support commands (portLogDump, supportSave, supportShow) or the Fabric
Manager Event Log
By default, the FICON group in the supportShow output is disabled. To enable the capture of FICON
data in the supportShow output, enter the supportshowcfgenable ficon command. After you
get confirmation that the configuration has been updated, the following will be collected and appear in
the output for the supportShow command:
• ficoncupshow fmsmode
• ficoncupshow modereg
• ficondbg dump rnid
• ficondbg log
• ficonshow ilir
• ficonshow lirr
• ficonshow rlir
• ficonshow rnid
• ficonshow switchrnid
• ficucmd dump -A
• Other detailed information for protocol-specific problems:
• Display port data structures using the ptDataShow command.
• Display port registers using the ptRegShow command.
Identifying ports
The ficonshow rlir command displays, among other information, a tag field for the switch port. You
can use this tag to identify the port on which a FICON link incident occurred. The tag field is a
concatenation of the switch domain ID and port number, in hexadecimal format. The following example
shows a link incident for the switch port at domain ID 120, port 93 (785d in hex):
