1. A computer program product for configuring functional capabilities of a computer system comprising two or more persistent memories and two or more replaceable functional units, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:

  • transferring, in response to a repair action for a first functional unit, first enablement data stored on the first functional unit to a servicer, wherein the first enablement data stored on the first functional unit is in a first persistent memory of the first functional unit, wherein the first enablement data is associated with a first unique identification number that corresponds to the first functional unit, the first enablement data specifying one or more functional capabilities of the first functional unit, and wherein the one or more functional capabilities are enabled in the first functional unit;

    erasing, after transferring the first enablement data in the first persistent memory to the servicer, the first enablement data from the first persistent memory;

    obtaining, by the servicer, in response to a replacement action for the first functional unit, a second unique identification number that corresponds to a second functional unit;

    transferring, from the servicer, the first unique identification number and the second unique identification number to a trusted environment in the computer system;

    transforming, in the trusted environment, the first enablement data to second enablement data by replacing the first unique identification number with the second unique identification number; and

    transferring the second enablement data to the second functional unit, wherein the second enablement data is stored in a second persistent memory of the second functional unit, wherein the second enablement data specifies one or more functional capabilities of the second functional unit, and wherein the one or more functional capabilities of the second functional unit are the same as the one or more functional capabilities of the first functional unit.
