Abstract

A method for tracking repair histories includes providing a field replaceable unit having a memory device, generating a repair history record associated with a repair request for the field replaceable unit, and storing the repair history record in the memory device. A computing system includes a field replaceable unit including a memory device configured to store a repair history record associated with repairs performed on the field replaceable unit.

Claims

1. A method for tracking repair histories, comprising:

generating a repair history record associated with a repair request for a field replaceable unit, wherein the repair history record comprises a repair summary record, and wherein generating the repair history record further comprises incrementing a total return count in the repair summary record responsive to the repair request; and

storing the repair history record in a memory device in the field replaceable unit.

2. The method of claim 1, wherein generating the repair history record further comprises generating a repair detail record corresponding to a given repair.

3. The method of claim 1, wherein generating the repair history record further comprises incrementing a total repair count in the repair summary record responsive to performing a physical repair on the field replaceable unit.

4. The method of claim 1, wherein generating the repair history record further comprises generating an engineering change order record that identifies a most recent engineering change order applied to the field replaceable unit.

5. The method of claim 4, wherein generating the engineering change order record includes generating the engineering change order record based on performing an engineering change order upgrade to the field replaceable unit.

6. The method of claim 2, further comprising:

storing a plurality of repair detail records; and

deleting an oldest one of the repair detail records responsive to the number of repair detail records exceeding a predetermined threshold.

7. The method of claim 6, wherein deleting the oldest one of the repair detail records further comprises deleting the oldest one of the repair detail records responsive to the number of repair detail records exceeding five.

8. A computing system comprising a field replaceable unit including a memory device configured to store a repair history record associated with repairs performed on the field replaceable unit, wherein the repair history record comprises a repair summary record that includes a total return count that is incremented in response to a repair request for the field replaceable unit.

9. The system of claim 8, wherein the repair history record comprises a repair detail record.

10. The system of claim 9, wherein the memory device is configured to store a plurality of repair detail records.

11. The system of claim 10, wherein the memory device is configured to store at most five repair detail records.

12. The system of claim 8, wherein the repair summary record further comprises a total repair count.

13. The system of claim 8, wherein the repair history record further comprises an engineering change order record that identifies a most recent engineering change order applied to the field replaceable unit.
