Overview of System Messages

This guide supports Fabric OS v6.4.0 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.
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.
