FICON concepts
1
• FICON Control Unit Port (CUP)
The internal port in a switch that assumes an FC address such that it is the FC DID used to
direct FICON traffic to the FICON Management Server.
• FICON Manager
Host communication includes control functions such as blocking and unblocking ports, as well
as monitoring and error-reporting functions.
• Hardware Configuration Definition (HCD)
HCD is an IBM interactive interface application that allows you to define the hardware
configuration for both the processor channel subsystem and the operating system running on
the processor.
• Information unit
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 or not 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.
