System module descriptions

FABR FABRIC refers to a network of Fibre Channel switches. The FABR error messages come from the
fabric daemon. The fabric daemon follows the FC-SW-3 standard for the fabric initialization process,
such as determining the E_Ports, assigning unique domain IDs to switches, creating a spanning tree,
throttling the trunking process, and distributing the domain and alias lists to all switches in the
fabric.
FABS Fabric OS system driver module.
FBC Firmware blade compatibility errors with the control processor (CP).
FCMC Fibre Channel miscellaneous messages relate to problems with the physical layer used to send Fibre
Channel traffic to and from the switch.
FCPD The Fibre Channel Protocol daemon is responsible for probing the devices attached to the loop port.
Probing is a process the switch uses to find the devices attached to the loop ports and to update the
Name Server with the information.
FCPH The Fibre Channel Physical Layer is used to send Fibre Channel traffic to and from the switch.
FCR Fibre Channel router-related traffic and activity on the fabric or back-end fabric.
FICN The FICN messages are generated during FICON emulation processing on an FCIP Tunnel.
FICU The FICON-CUP daemon handles communication with fibre connectivity (FICON) on IBM FICON
storage devices. Errors to this module are usually initiation errors or indications that FICON-CUP
prerequisites have not been met, such as a license key, core process ID (PID), and secure mode on
the fabric.
FKLB Fabric OS I/O kernel library module.
FLOD FLOD is a part of the Fabric Shortest Path First (FSPF) protocol that handles synchronization of the
link state database (LSDB) and propagation of the link state records (LSRs).
FSPF Fabric Shortest Path First (FSPF) is a link state routing protocol that is used to determine how frames
should be routed. These messages are about protocol errors.
FSS The Fabric OS state synchronization framework provides facilities by which the active control
processor (CP) can synchronize with the standby CP, enabling the standby CP to take control of the
switch nondisruptively during failures and software upgrades. These facilities include version
negotiation, state information transfer, and internal synchronization functions, enabling the
transition from standby to active operation.
FSS is defined both as a component and a service. A component is a module in the Fabric OS,
implementing a related set of functionality. A service is a collection of components grouped together
to achieve a modular software architecture.
FSSM The Fabric OS state synchronization management module is defined both as a component and a
service. A component is a module in Fabric OS, implementing a related set of functionality. A service
is a collection of components grouped together to achieve a modular software architecture.
FV Flow Vision is a network diagnostic tool that allows you to simulate, monitor, and capture the network
traffic pattern to validate the connectivity, performance, and hardware components. FV messages
indicate operations associated with a flow in Flow Vision.
HAM HAM is a user-space daemon responsible for high availability management.
HAMK This is the kernel module for the high availability management (HAM) daemon.
HIL Hardware independent layer.
HLO HLO is a part of the Fabric Shortest Path First (FSPF) protocol that handles the HELLO protocol
between adjacent switches. The HELLO protocol is used to establish connectivity with a neighbor
switch, to establish the identity of the neighbor switch, and to exchange FSPF parameters and
capabilities.
