Brocade FICON Administrator’s Guide (Supporting Fabric OS v7.3.0) - Manual (Page 16)

A unit of FICON data consisting of from one to four Fibre Channel frames.
• Link Incident Record Registration (LIRR)
The LIRR Extended Link Service (ELS) requests that the recipient add the requesting port to its
list of ports that are to receive a Registered Link Incident Report (RLIR).
• Node
A node is an endpoint that contains information. It can be a computer (host), a device controller,
or a peripheral device, such as a disk array or tape drive. A node has a unique 64-bit identifier
known as the Node_Name. The Node_Name is typically used for management purposes.
• Prohibit Dynamic Connectivity Mask (PDCM) and connectivity attributes
PDCM controls whether communication between a pair of ports in the switch is prohibited.
Connectivity attributes control whether all the communication is blocked for a port.
• Read Record Set (RRS)
RRS is an IBM Channel-initiated CCW command. The Brocade FCIP FICON Acceleration
License allows the emulation of command chains that include this CCW command. The command
is used in IBM z/OS Global Mirror configurations to read updates from a volume in an active
mirroring session.
• Registered Link Incident Report (RLIR)
RLIR ELS provides a way for a node port to send an incident record to another node port.
• Request Node Identification Data (RNID)
RNID ELS acquires the associated node’s identification data, which provides configuration
discovery and management purpose information.
• Resource Measurement Facility (RMF)
Performance monitoring software that gathers transaction data from the environment and
generates performance reports. All Level II reports, which include port statistics, require the
FICON Control Unit Port (CUP) and FICON Management Server (FMS).
• Systems Operations (SysOps)
SysOps provides the ability to monitor and control all subsystems in a sysplex from any system in
the sysplex. This includes controlled startup, controlled shutdown, and automated recovery of
software resources.
• Sysplex
In IBM mainframe computers, a Systems Complex, commonly called a sysplex, allows multiple
processors to be joined into a single unit, sharing the same sysplex name and Couple Data Sets.
• IPL file
The initial program load (IPL) File, located in nonvolatile storage, contains the current, active
configuration settings for the FICON director. If functions to initialize data on the Director during a
POR event. When the "Active=Saved" FICON CUP mode register bit setting is on, any active
configuration in switch memory is automatically saved to the IPL file.
FICON configurations
There are two types of FICON configurations that are supported using Brocade Fabric OS: switched
point-to-point and cascaded topologies.
