A facility is a hardware device, a protocol, a feature, or a module of the system software. System message SEVERITY codes range from 0 to 7 and reflect the severity of the condition. The lower the number, the more serious the situation. Table 1-2 lists the severity levels. Table 1-2 System Message Severity Levels Level 0 - emergency 1 - alert 2 - critical 3 - error 4 - warning 5 - notification 6 - informational 7 - debugging Description System unusable Immediate action needed Critical condition Error condition Warning condition Normal but significant condition Informational message only Appears during debugging only MNEMONIC is a code that uniquely identifies the system message. Message-text is a text string that describes the condition. This portion of the message might contain detailed information about the event, including terminal port numbers, network addresses, or addresses that correspond to locations in the system memory address space. Because the information in these variable fields changes from message to message, it is represented here by short strings enclosed in square brackets ([ ]). A decimal number, for example, is represented as [dec]. Table 1-3 lists the representations of variable fields and the type of information in the fields.
