1 System Module Descriptions System Module Descriptions Table 5 provides a summary of the system modules for which messages are documented in this reference guide; the system modules are listed alphabetically by name. TABLE 5 System Module Descriptions System Module Description AG Access Gateway allows multiple hosts (or HBAs) to access the fabric using fewer physical ports. Access Gateway mode transforms the Brocade 200E as well as embedded switches into a device management tool that is compatible with different types of fabrics, including Brocade-, Cisco-, and McDATA-based fabrics. AUTH Authentication error messages indicate problems with the authentication module of the Fabric OS. BKSW Messages generated by the Blade Fabric OS kernel software watch dog module. BL BLL BM CDR CER CONF EM EVMD FABR Blade error messages are a result of faulty hardware, transient out-of-memory conditions, application specific integrated circuit (ASIC) errors, or inconsistencies in the software state between a blade and the EM (environment monitor) module. Bloom is the name of the application specific integrated circuit (ASIC) used as the building block for third-generation hardware platforms. 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. FABS Fabric OS system driver module. FBC Firmware blade compatibility errors with control processor (CP). FCIP Fibre Channel over IP port configuration messages. FCMC FCPD FCPH FCR 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. 14 Fabric OS Message Reference 53-1000437-01
