This notification is sent when a resource detects a new alarm state with severity warning. The notification is also used to change severity and/or additional text of an alarm. The combination of ManagedObject and MajorType/MinorType is always unique and can be used by management systems to correlate alarm, alarm change, and alarm clear. A corresponding row will be created in the Alarm Table, (eriAlarmActiveAlarmTable). The sequence number will increase for every notification and can be used to detect lost notifications. A management system should be prepared for appending text to additional text, indicated by the eriAlarmNObjMoreAdditionalText varbind, and sent with eriAlarmAppendInfo. (Note do not confuse this with a change of additional text.) A management system should also be prepared to receive a resource ID (OID) identifying the alarming resource if the system sending the notification can provide that information. In that case, eriAlarmNObjResourceId will be set to 'true' and the resource ID will be sent in an eriAlarmAppendInfo notification.
