CAUTION
Alarm settings are enabled as part of your installation. Changes to alarm settings should not be made for simple convenience; this may conceal underlying problems that should be resolved. If you find an alarm is persistent, discuss the situation with HP technical support before making changes.
Indicators and Propagation
Alarms are generated at the attribute level of the grid. When an issue is detected, the alarm is propagated up through the grid hierarchy. The associated attribute, component, service, and node information on the NMS are all changed to reflect the alarm state. As a result, you can view the general alarm state at the grid level, then drill down through the service components to locate the specific details. (See
Figure 16: “Sample Alarm Indicator Propagation” on page 30.)
Each individual service reflects the highest alarm state of its compo- nents. If more than one alarm exists on a node, the node always reflects the highest and most serious alarm level (see “Alarm Levels and Indi- cators” below). Locations (Site A and Site B) display the highest alarm level of the nodes on that branch.
Refer to Figure 16 on page 30 for an example. One node’s SSM indi- cates a minor alarm state while its LDR indicates an unknown state. That node icon displays the unknown alarm state (the higher alarm level). Another node in the same group shows a major alarm on the AMS service. The group location propagates the “unknown” alarm indicator. The color and icon of each service, node, and location reflects its highest alarm state along its branch of the Navigation Tree.
Alarm Levels and Indicators
NMS alarms are organized into a hierarchy of levels. The hierarchy reflects the seriousness of a grid issue. There are six alarm levels in the
