A method of virtually removing field replaceable units (FRUs) from a computer system during concurrent maintenance operations. Firmware within a flexible service processor (FSP) assigns unique resource identification (RID) numbers to each FRU in the computer system. The firmware collects vital product data (VPD) for each FRU and generates a duplicate test shared library, which is stored in a memory directory corresponding to the FSP. When the firmware receives input from a graphical user interface (GUI) that includes at least a first FRU selected for virtual removal from the computer system, the firmware adds the RID number of the selected FRU to the memory directory and recollects VPD. The FSP subsequently ignores any FRUs corresponding to RID numbers stored in the memory directory during operation of the computer system.
