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.
Responding to a system message
This section provides procedures on gathering information on system messages.
Looking up a system message
Error messages in this manual are arranged alphabetically. To look up an error message, copy
down the module (see Table 6 on page 13) and the error code and compare this with the Table of
Contents to determine the location of the information for that error message.
The following information is provided for each message:
• Module and code name for the error
• Message text
• Probable cause
• Recommended action
• Message severity
Gathering information about the problem
Questions to ask yourself when troubleshooting a system message are as follows:
• What is the current Fabric OS level?
• What is the switch hardware version?
TABLE 5 severity levels of a message
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.
