The content update refers to the Hardware Model Normalization Content Service, which is a feature that enables users to normalize the details of their hardware and consumable models by comparing them against the data in the content service1.
The content service provides hardware lifecycle data, such as end-of-life (EOL), end-of-support (EOS), and end-of-availability (EOA) dates, for the normalized models2.
Once the content update adds hardware lifecycle data to your instance, you can delete or deactivate the models that you do not need or use3.
To delete a model, you can navigate to Hardware Asset Management > Model Management > Hardware Models, select the model you want to delete, and click Delete3.
To deactivate a model, you can navigate to Hardware Asset Management > Model Management > Hardware Models, select the model you want to deactivate, and uncheck the Active box3. References:
