FICON information
You can display link incidents, registered listeners, node identification data, and FRU failures, as
described in the following sections.
Link incidents
The registered link incident record (RLIR) ELS contains the link incident information sent to a
listener N_Port.
To display link incidents, connect to the switch, log in as user, and enter one of the following
commands:
• For the local switch: ficonShow rlir
• For all switches defined in the fabric: ficonShow rlir fabric
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):
