Monitoring physical component health
When a warning or critical error occurs in a physical component, the health state of the affected component changes and generates an alert. You can use the alert description and product knowledge to troubleshoot the issue.
If a physical 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 physical component count values that are stored in the database to detect long term trends.
The following rules are available for each component:
Two collection rules save the count values to the database (DB) and data warehouse (DW) for the specified physical components of a specified class per parent instance.
One warning alert is generated and updated in the active alerts folder in SCOM if a physical-component count changes. If the alert rule for the specified physical component is enabled, the rule collects data every 90 minutes and calculates the total component count. Multiple alert generations are suppressed to reduce the number of alerts generated for the same failure.
Table 1 lists the collection and alert rules that are enabled by default and Table 2 lists the rules that are disabled by default. The total counts for enclosures and LUN storage service nodes includes all of the components in the class hierarchy. The disabled rules are optional for investigating problem alerts. You can enable one or more of the disabled rules when a physical component or hardware problem requires investigation.
