1 System Module Descriptions TABLE 5 System Module BM CDR CER CONF EM EVMD FABR FABS FBC FCIP FCMC FCPD FCPH FCR FICU FKLB FLOD FSPF FSS System Module Descriptions (Continued) Description Blade management error messages are a result of autoleveling firmware upgrades performed by the control processor (CP). Condor application specific integrated circuit (ASIC) driver error messages. This is the core edge routing module on the Brocade director platforms. Status messages for configUpload and configDownload operations. The environmental monitor (EM) manages and monitors the various field replaceable units (FRUs), including the port cards, control processor (CP) blades, blower assemblies, power supplies, and world-wide name (WWN) cards. EM controls the state of the FRUs during system startup, hot-plug sequences, and fault recovery. EM provides access to and monitors the sensor and status data from the FRUs and maintains the integrity of the system using the environmental and power policies. EM reflects system status by way of CLI commands, system light emitting diodes (LEDs), and status and alarm messages. EM also manages some component-related data. This is the event management module. FABRIC refers to a network of Fibre Channel switches. The FABRIC 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 control processor (CP). Fibre Channel over IP port configuration messages. 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. 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 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. 14 Fabric OS Message Reference 53-1000600-02
