System module descriptions 1 TABLE 6 System module FABR FABS FBC FCMC FCPD FCPH FCR FICN FICU FKLB FLOD FSPF FSS FSSM FV HAM HAMK HIL HLO System module descriptions (Continued) Description 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. Fabric OS system driver module. Firmware blade compatibility errors with the control processor (CP). Fibre Channel miscellaneous messages relate to problems with the physical layer used to send Fibre Channel traffic to and from the switch. 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. The 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 back-end fabric. The FICN messages are generated during FICON emulation processing on an FCIP Tunnel. 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. 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 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.
