The messages are organized first by event type, reliability, availability, and serviceability log (RASLog) or AUDIT, and 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 may 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 system messages. The Fabric OS maintains an internal system message log of all messages. All messages are tagged by type as either RASLog system error messages, Audit messages, or both. RASLog error messages are primarily designed to indicate and log abnormal, error-related events, whereas Audit messages record events such as login failures, zone, or configuration changes. Fabric OS supports a different methodology for storing and accessing each type of message. System Error Message Logging The RASLog service generates and stores messages related to abnormal or erroneous system behavior. It includes the following features: • All RASLog error messages are saved to nonvolatile storage by default. • The system error message log can save a maximum of 1024 messages in random access memory (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. • Messages are numbered sequentially from 1 to 2,147,483,647 (0x7ffffff). The sequence number will continue to increase beyond the storage limit of 1024 messages. The sequence number can be reset to 1 using the errClear command. The sequence number is persistent across power cycles and switch reboots. • By default, the errDump and errShow commands display all of the system error messages.
