About RLIR
The Registered Link Incident Report (RLIR) application provides a method for a switch port to send a Link Incident Record (LIR) to a registered Nx port.
When an LIR is detected in FICON-enabled switches in the Cisco MDS 9000 Family from an RLIR Extended Link Service (ELS), the switch sends that record to the members in its Established Registration List (ERL).
In case of multiswitch topology, a Distribute Registered Link Incident Record (DRLIR) Inter-Link Service (ILS) is sent to all reachable remote domains along with the RLIR ELS. On receiving the DRLIR ILS, the switch extracts the RLIR ELS and sends it to the members of the ERL.
The Nx ports interested in receiving the RLIR ELS send the Link Incident Record Registration (LIRR) ELS request to the management server on the switch. The RLIRs are processed on a per-VSAN basis.
The RLIR data is written to persistent storage when you copy the running configuration to the startup configuration.
