System Module Descriptions 1 TABLE 5 System Module FCPD FCPH FCR FICON FICON CUP FICU FKLB FLOD FSPF FSS FSSM FW HAM HAMK HIL HLO HMON HTTP IBD IBPD System Module Descriptions (Continued) Description 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. Fibre Channel Physical Layer is used to send Fibre Channel traffic to and from the switch. Fibre Channel router-related traffic and activity on the fabric or backend fabric. The FICN-1xxx and FICN-5yyy messages are generated during FICON emulation processing on an FCIP Tunnel. FICU-#### messages indicate that something has occurred which affects the control unit port (CUP) for the switch/director. These messages can mean anything from configuration-related failures to internal software errors. 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. Fabric OS I/O kernel library module. 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). 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. 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. 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 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 is a user space daemon responsible for high availability management. This is the kernel module for the high availability management (HAM) daemon. Hardware independent layer. 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. Health monitor. HTTP error messages. This raslog generates messages related to port restart failure. IBPD stands for iSCSI gateway daemon on a blade processor (BP). It manages iSCSI initiator access control, session authentication, and session/connection statistics. Fabric OS Message Reference 15 53-1001157-01
