Error Message Format

This chapter describes how error messages are formatted. Not all messages indicate problems; some messages are only informational, while others help diagnose problems.

Messages are listed by the facility (hardware device, protocol, or a module or system software) that produces the messages. Within each facility, messages are listed by the severity level, from
1 through 7. Each message is followed by an explanation and a recommended action. Messages appear only when the system remains operational.

Message Structure

Messages similar to the following will appear in the error log:

04/27/1999-12:13:58 07 tTnInTsk01 CLI-7-CLITNLOG

cliTelnetd: client@171.71.25.240: telnet.01: disconnected

These messages are structured as follows:

mm/dd/yyyy-hh:mm:ss slot# taskname facility-severity-MNEMONIC description

where

mm/dd/yyyy-hh:mm:ss is the date and time of the error/event,slot# is the slot number to which the message applies, andtaskname is the name of the task to which the message applies.

The remaining parts of the messages are described in the rest of this chapter.

Facility Codes

A facility code consists of two or more uppercase letters that indicate the reference facility to which the message refers. A facility can be a hardware device, a protocol, or a portion of the system software. (See Table 1-1.)

Severity Levels

A severity level code is a single digit from 0 to 7 that reflects the severity of the condition. The lower the number, the more serious the situation. (See Table 1-2.)

Table 1-2: Message Severity Levels

Severity Level	Description
1 - fatal	Platform needs reset
2 - alert	Major alert condition
3 - alert	Minot alert condition
4 - error	Error condition detected
5 - warning	Warning condition detected
6 - notice	Normal but significant
7 - info	Informational

Mnemonic Codes

The MNEMONIC code uniquely identifies the error message. All mnemonics are all uppercase character strings.

Description Text Strings

A description text string describes the condition. Sometimes it contains detailed information about the event, including terminal port numbers, network addresses, or addresses that correspond to locations in the system memory address space. Because these variable fields can change from message to message, they are represented by short strings in square brackets ([ ]). A decimal number, for example, is represented as [dec]. (See Table 1-3.)

Table 1-3: Representation of Variable Fields in Messages

Representation	Type of Information
[dec]	Decimal
[chars]	Character string
[hex]	Hexadecimal integer
