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): switch:admin> ficonshow rlir { {Fmt Type PID Port Incident Count TS Format Time Stamp 0x18 F 785d00 93 1 Time server Thu Apr 22 09:13:32 2004 Port Status: Link not operational Link Failure Type: Loss of signal or synchronization Registered Port WWN Registered Node WWN 50:05:07:64:01:40:16:03 50:05:07:64:00:c1:69:ca Type number: 002064 Model number: 103 Manufacturer: IBM Plant of Manufacture: 02 Sequence Number: 0000000169CA tag: 155d Flag 0x10 Node Parameters 0x200115 Switch Port WWN Switch Node WWN 20:5d:00:60:69:80:45:7c 10:00:00:60:69:80:45:7c Type number: SLKWRM Model number: 24K Manufacturer: BRD Plant of Manufacture: CA Sequence Number: 000000000078 tag: 785d } } The Local RLIR database has 1 entry.
