A computer implemented method for replacing components of a data processing system, comprising in response to a detection of a newly added component at a specific location; reading its customization data from a data storage and querying a persistent database to determine if functional capabilities according to customization data are specified for this specific location; depending on a result of determining the functional capabilities and of querying the database if it contains customization data either: disabling the component; or enabling the component and storing in the database the customization data; or enabling the component and replacing the customization data in the database; or storing the customization data in the data storage of the component and enabling the component.

Replacing components of a data processing system

A method for dynamically assigning a plurality of storage devices to a plurality of controllers within a storage unit, the method including: sensing each storage device from the plurality of storage devices; assigning each one of the storage devices to a respective controller from the plurality of controllers; monitoring at least one of each storage device, each controller, and a link between each storage device and the respective controller; upon a failure of at least one of the link, one of the storage devices and one of the controllers, generating a list of components; transmitting the list to another controller; and establishing a new assignment for each of the components on the list. A storage unit and a computer program product are provided.
