Working with discovered CIs
Discovery products automate the process of populating BMC Atrium CMDB. When these products discover IT hardware and software, they create CIs and relationships from the discovered data.
For example, you might use BMC Configuration Automation for Clients or BMC Atrium Discovery to populate BMC Atrium CMDB. BMC Configuration Automation for Clients can discover CI types such as computer system, processor, operating system, and software product. BMC Atrium Discovery can discover CI types, such as computer system, cluster, application, and business service.
When data providers, such as discovery products, put data into BMC Atrium CMDB, this data is partitioned into separate datasets. The Reconciliation Engine component of BMC Atrium CMDB reconciles these datasets into a consolidated production dataset that you use as the single source of reference for your IT environment.
The Reconciliation Engine identifies CIs for reconciliation from discovery products and from BMC Asset Management, merges the identified records to the production dataset based on a precedence value, and purges obsolete configuration data from the production dataset. The production dataset is named BMC Asset.
Data consumers, such as BMC Asset Management, read data from the production dataset. You can use BMC Asset Management to view, modify, and work with the discovered CIs. You can also use BMC Asset Management to create CIs that are not discovered, as described in Creating CIs.
BMC discovery products populate key CI fields so that CIs can be uniquely identified during reconciliation. If you create a CI that might later be discovered, you must enter values in these fields that match the values populated by discovery products. For example, the CI Description field can be used during reconciliation to identify a CI. Failure to enter this data correctly can result in duplicate CIs. For information about how BMC discovery products identify CIs, see CMDB synchronization and Default CDM Mapping.
