Configuring functional capabilities of a computer system
First Claim
1. A method for configuring functional capabilities of a computer system that comprises two or more persistent memories and two or more replaceable functional units, the 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.

Abstract
Provided is a method for configuring the functional capabilities of a computer system. The computer system may include a persistent memory and a replaceable functional unit. The method may include transferring, in response to a repair action for the functional unit, enablement data that is stored on the functional unit to the persistent memory. The enablement data may specify one or more functional capabilities of the functional unit that are enabled. The method may further include erasing the enablement data from the functional unit after it has been transferred to the persistent storage. The method may further include obtaining a second unique identification item from a replacement unit. The method may further include obtaining new enablement data. The new enablement data may be transferred to the replacement unit.
