Set a deletion strategy

Set a deletion strategy when you want to take action on a related configuration item (CI) that Discovery can no longer find through pattern discovery. You can delete the main CI only when it is an Application or Cloud Resource pattern type.

Avant de commencer

• CIs: a main CI and related CIs that the discovery process found through pattern discovery
• Role required: cloud_admin, service_mapping_admin, discovery_admin, or admin

Pourquoi et quand exécuter cette tâche

You can set a deletion strategy for all discovered CIs, including configuration file CIs. However, the way you access the deletion strategy for tracked configuration files differs from the procedure in this topic. See Set the deletion strategy for tracked configuration files for instructions.

Procédure

1. Open the list of related CI types by entering sa_ci_to_pattern.list in the application filter.
2. Filter the list to find the CI type that is related to a main CI through pattern discovery.
   If you want to set a deletion strategy for a cloud database, search the list for cmdb_ci_cloud_database CI type.

   Notice that the cmdb_ci_cloud_database CI types have the Is Main CI value set to true. This indicates that you can set a deletion strategy for both AWS and Azure databases, even if they are the main CI that cloud discovery finds.

   

3. From the list view, double click the value in the field in the Deletion Strategy column.
4. Select a new value:

   Value	Description
   Keep	Preserves the configuration file CI record and makes no other changes to the record. This option is the default setting.
   Delete	Deletes the configuration file CI record from the CMDB, and the relationship to the main CI.
   Mark as absent	Marks the Status [install_status] field of the configuration file CI record as Absent, meaning that Discovery cannot find the tracked configuration file. This status does not instruct the system to delete the actual CI or the relationship. Remarque : There are two tables that do have their CIs deleted if marked as absent: cmdb_ci_network_adapter and cmdb_ci_ip_address.
   Delete relations	Deletes only the CI relationships between the related CI and the main CI.
   Mark as retired	Marks the Status [install_status] field of the configuration file CI record as Retired, meaning that Discovery no longer uses this configuration file. This status does not instruct the system to delete the actual CI or the relationship.
