HP StorageWorks Fabric OS 5.X Diagnostics and System Error Messages Reference Guide (AA-RVHZB-TE, September 2005)

Fabric OS 5.x diagnostics and system error messages reference guide 81
1 Introduction to System Messages
This guide supports Fabric OS 5.x and contains system messages that you can use to diagnose and fix
problems with the switch or fabric. The messages are organized 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 book 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:
• Message severity levels, page 81
• Overview of the system messages, page 81
• View or configure the system message logs, page 84
• Reading a system message, page 85
• Responding to a system message, page 88
• System module descriptions, page 89
Message severity levels
There are four levels of severity for messages, ranging from Critical (1) to Info (4). In general, the
definitions are wide ranging and are to be used as general guidelines for troubleshooting. For all cases,
you should look at each specific error message description thoroughly before taking action. System
messages have the following severity levels.
Overview of the 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 (RASLog), page 82
• Audit logging, page 82
• Dual-CP systems, page 83
• ”System logging daemon” on page 83
• Port logs, page 83
• Panic dump and core dump files, page 83
• Trace dumps, page 84
• supportSave command, page 84
1 = CRITICAL Critical-level messages indicate that the software has detected serious
problems that will cause a partial or complete failure of a subsystem if not
corrected immediately; for example, a power supply failure or rise in
temperature must receive immediate attention.
2 = ERROR Error-level messages represent an error condition that does not impact overall
system functionality significantly. For example, error-level messages might
indicate time-outs on certain operations, failures of certain operations after
retries, invalid parameters, or failure to perform a requested operation.
3 =
WARNING
Warning-level messages highlight a current operating condition that should be
checked or it might lead to a failure in the future. For example, a power supply
failure in a redundant system relays a warning that the system is no longer
operating in redundant mode unless the failed power supply is replaced or
fixed.
4 = INFO Info-level messages report the current non-error status of the system
components: for example, detecting online and offline status of a fabric port.
