1 System module descriptions TABLE 6 System module BM C2 C3 C4 CAL CCFG CDR CHS CNM CNMC CONF CTAP CVLM DOT1 ECC EM ERCP ESM ESS ESW EVMD System module descriptions (Continued) Description Blade management error messages are a result of autoleveling firmware upgrades performed by the control processor (CP). C2 error messages indicate problems with the 8 Gbps-capable FC module of the Fabric OS. C3 error messages indicate problems with the 16 Gbps-capable FC module of the Fabric OS. C4 error messages indicate problems with the 32 Gbps-capable FC module of the Fabric OS. Common Access Layer (CAL) provides XML interface for configuring switch parameters in an object model. CCFG error messages indicate problems with the Converged Enhanced Ethernet (CEE) configuration module of the Fabric OS. Driver error messages. Error messages reporting the problems in the management of the blades in the different slots of the chassis. Cluster Node Manager (CNM) is a software daemon module of the Fabric OS. The messages from CNM are problems encountered by CNM, warnings, or information to the user of events. Controller Area Network Management Interface Controller (CANMIC) module is a software daemon module of the Fabric OS. This module interacts with the Enclosure Manager through the CANMIC controller and reports information and error messages to the user. Status messages for configUpload and configDownload operations. A user-space daemon that forwards non-performance-critical messages from the TAPE driver to the Crypto Virtual LUN Controller (CVLC) and Security Processor (SP), and vice versa. This module also maintains a cache of recently acquired keys, reducing requests to the key vault itself. Crypto Virtual LUN Manager (CVLM) is a software module of the Fabric OS. The messages of CVLM are problems encountered by CVLM, warnings to alert the user, or information to the user. DOT1 error messages indicate problems with the 802.1x authentication module of the Fabric OS. Error Checking and Correction (ECC) error messages indicate single-bit and multiple-bit errors in the Dynamic Random Access Memory (DRAM) devices. ECC is a technology that helps to correct memory errors. 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 CLI commands, system light emitting diodes (LEDs), and status and alarm messages. EM also manages some component-related data. Error Reporting Control Process (ERCP) messages captures the corenet and memory subsystem errors. Extension Services Module (ESM) provides management control and reporting for extension features such as FCIP and IPEX as well as their associated configurations. Exchange Switch Support (ESS) error messages indicate problems with the ESS module of the Fabric OS. ESS is an SW_ILS mechanism utilized by switches to exchange vendor and support information. ESW error messages indicate problems with the Ethernet switch module of Fabric OS. EVMD is the event management module. 28 Brocade Fabric OS Message Reference 53-1004119-01
