System Module Descriptions

FCR Fibre Channel router related traffic and activity on the fabric or backend fabric.
FICU The FICON-CUP daemon handles communication with 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 PID, and secure mode on the
fabric.
FKLB Fabric OS I/O kernel library module.
FLOD FLOOD is a part of the FSPF (fabric shortest path first) protocol that handles
synchronization of the link state database (LSDB) and propagation of the link state records
(LSR).
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.
FW FW is the Fabric Watch module. This module monitors thresholds for many switch
subsystems: for example, temperature, voltage, fan speed, and switch status. Any changes
that cross a specified threshold are reported to the system message log.
HAM HAM is a user space daemon responsible for high availability management.
HAMK This is the kernel module for the HAM daemon.
HIL Hardware independent layer.
HLO HLO is a part of 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.
HMON Health monitor.
HTTP HTTP error messages.
IBPD IBPD stands for iSCSI gateway daemon on BP. It manages iSCSI initiator access control,
session authentication, and session/connection statistics.
