Dell Brocade 6520 Message Reference Supporting Fabric OS v7.1.0 - Page 50

1 System module descriptions System module descriptions Table 6 provides a summary of the system modules for which messages are documented in this guide; the system modules are listed alphabetically by name. A module is a subsystem in the Fabric OS. Each module generates a set of numbered messages. TABLE 6 System module descriptions System module Description AG AN ANV AUTH BKSW BL BLS BM C2 C3 CAL CCFG CDR CHS CNM CONF CTAP CVLC CVLM DOT1 Access Gateway (AG) allows multiple hosts (or HBAs) to access the fabric using fewer physical ports. Access Gateway mode transforms the Brocade switches 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. Error or warning messages from the Bottleneck Detection module, including notification of detected bottlenecks. ANV error messages indicate problems with the driver that deal with the ENET application-specific integrated circuits (ASICs) on the Fabric OS. They can be software- or hardware-related errors. Authentication error messages indicate problems with the authentication module of the Fabric OS. BKSW messages are generated by the Fabric OS blade kernel software watchdog module. BL error messages are a result of faulty hardware, transient out-of-memory conditions, ASIC errors, or inconsistencies in the software state between a blade and the environment monitor (EM) module. Fibre Channel over IP port configuration messages over the Brocade 7800 and FX8-24 blade. 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. 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. 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 Controller (CVLC) is a software module running on blade FOS (BFOS). The messages of CVLC are problems encountered by CVLC, warnings to alert the user, or information to the user. 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. 28 Fabric OS Message Reference 53-1002749-01
