Hardware Model Creation in the cmdb_hardware_product_model

[klf1123]

When asset management originated, I recall being able to make hardware models in the cmdb_hardware_product_model table for the Service Catalog and Asset Creation. The CIs would be discovered and update, but the models did not need to reflect what was discovered. At what point did the requirement begin that the model needed to be created by discovery and reverse from an asset first creation to a CI first creation? How does this work for asset management and model management? The software models allow for a discovery model and mapping but the hardware does not, and I cannot figure out how to clean-up the model table or a best practice to do so.

Dear @Kieran Anson  How would you handle Model switches if a Model has been normalized manually and then a new Model gets created by a discovery Source like Intune. Is there any other possibility to prevent Model switches by the IRE. Is there a possibility to prohibit the Model Change or Override

[klf1123]

Yes, this is exactly what I am trying to figure out as well. The source tools even override themselves. I can't seem to see how the IRE would help with this either it doesn't seem to stop the source from creating new models and moving everything over to it.

You would use a reconciliation to prevent your data source from overriding the field value.

Dear Kieran, I know the usecase of reconciliation Rules. But how would you create a Reconciliation Rule on this topic. 

Case 1: Hardware Models and Assets are being created manually by Technical Personal and Procurement and they normalized the Hardware Model and everything correctly. Lets say you have Intune as your main MDM Tool and want to provision your Phones then. After integrating Service Graph Connector the Model will be constantly override the Model or even create a new Model and map your Data in a totally different Model. How would you create the Reconciliation Rule on a Record what does not went through a specific Data Source. The Hardware Model is a Manual Entry.
