copyAlarmLevel is a notification varbind reporting the warning or severity level of the copy-operation alarm trap it accompanies, per its description "the message warning level". An admin's trap receiver uses this to prioritize copy-related alerts, since a copy failure or issue reported at a higher severity level warrants faster attention than a purely informational one. For example, a trap carrying copyAlarmLevel set to a high severity value alongside a failed copy would typically page an admin, while a low severity value might just be logged.
