1 Responding to a System Message 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. 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. Responding to a System Message This section provides procedures on gathering information on system messages, including: • "Looking Up a System Message" on page 1-12 • "Gathering Information About the Problem" on page 1-13 • "Support" on page 1-13 • "Panic Dump and Core Dump Files" on page 1-14 • "Trace Dumps" on page 1-14 • "supportSave Command" on page 1-14 Looking Up a System Message Error messages are arranged in this manual alphabetically. To look up an error message, copy down the module (see Table 1-4 on page 1-15) and the error code and compare this with the Table of Contents to determine the location of the information for that error message. Information provided by this book is as follows: • Module and code name for the error • Message text • Probable cause 1-12 Fabric OS Message Reference Publication Number: 53-1000242-01
