HP StorageWorks 2/16V Brocade Fabric OS Message Reference Guide (53-1000242-01 - Page 55

Introduction to System Messages Chapter 1 This guide supports Fabric OS v5.2.0 and documents system messages that you can use to diagnose and fix problems with the switch or fabric. The messages are organized first by event type, AUDIT or RASLog, then alphabetically by module name. A module is a subsystem in the Fabric OS. Each module generates a set of numbered messages. For each message, this guide provides message text, probable cause, recommended action, and severity level. There can be more than one cause and more than one recommended action for any given message. This guide discusses the most probable cause and typical action recommended. This chapter provides an introduction to the system messages. The following topics are discussed: • "Overview of System Messages," next • "Viewing and Configuring System Message Logs" on page 1-4 • "Reading a RAS System Message" on page 1-8 • "Responding to a System Message" on page 1-12 • "System Module Descriptions" on page 1-15 Overview of System Messages This section provides information on the various logs saved by the system and how to view the information in the log files, including the following topics: • "System Message Log" on page 1-1 • "System Logging Daemon (syslogd)" on page 1-2 • "System Console" on page 1-3 • "Port Logs" on page 1-3 System Message Log The Fabric OS maintains an internal system message log of all messages. All messages are generically logged as RAS messages, then tagged by type as either Audit or RASLog messages, or both. Features of the system message log include the following: • The system message log saves all messages to nonvolatile storage by default. • The system message log can save a maximum of 1024 messages in RAM. • The system message log is implemented as a circular buffer. When more than maximum entries are added to the log file, old entries are overwritten by new entries. Fabric OS Message Reference 1-1 Publication Number: 53-1000242-01
