Chapter 2 System Message Overview
How to Read System Messages
• SEVERITY is a single-digit code from 0 to 7 that reflects the severity of the condition. The lower
the number, the more serious the situation. Table 2-2 lists the message severity levels.
• MNEMONIC is a code that uniquely identifies the message.
• Message-text is a text string describing the condition. This portion of the message sometimes
contains detailed information about the event, including terminal port numbers, network a ddresses,
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 2-3 lists the variable fields in messages.
