Introduction to System Messages

This guide supports Fabric OS v5.3.0 and documents system messages that can help you diagnose

and fix problems with a switch or fabric. 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.

Overview of 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.

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 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.
