800 Series Alarm Messages

The system inventory and maintenance service reports system changes with different degrees of severity. Use the reported alarms to monitor the overall health of the system.

Alarm messages are numerically coded by the type of alarm.

For more information, see Fault Management Overview.

In the alarm description tables, the severity of the alarms is represented by one or more letters, as follows:

  • C: Critical

  • M: Major

  • m: Minor

  • W: Warning

A slash-separated list of letters is used when the alarm can be triggered with one of several severity levels.

An asterisk (*) indicates the management-affecting severity, if any. A management-affecting alarm is one that cannot be ignored at the indicated severity level or higher by using relaxed alarm rules during an orchestrated patch or upgrade operation.

Note

Degrade Affecting Severity: Critical indicates a node will be degraded if the alarm reaches a Critical level.
