Monitoring logical component health
When a warning or critical error occurs in a logical component (such as a storage or virtual volume), the health state of the affected component changes and generates an alert. You can use the alert description and product knowledge to decide what action is necessary.
If a logical component fails and disappears from the data collected by ESI Service, an alert is generated to investigate the failure. You can use this alert to determine root cause of a failure. You can also use the logical component count values that are stored in the database to detect long term trends.
The collection and alert rules that are enabled and disabled by default for system components are described in Monitoring physical component health.
