Abstract

The invention provides a method for automatically positioning an internal memory fault. The method includes the following steps: reading a value of a machine check architecture (MCA) register, analyzing the value to obtain physical address of a fault internal memory, obtaining staggering state of the internal memory between a socket, obtaining the socket value of the fault internal memory according to the staggering state, acquiring channel value and excursion in the channel according to the staggering state of the internal memory physical address and the internal memory between the socket, acquiring groove position information of the fault internal memory according to the excursion in the channel and positioning the fault internal memory according to the socket value, the channel value and the groove position information of the fault internal memory. The method can accurately position groove position of the fault internal memory, maintains the internal memory matched with other methods, improves internal memory fault monitoring rate and reduces data center operation and maintenance cost. A device for automatically positioning the internal memory fault is further provided.

Description

Technical field [0001] The invention relates to the technical field of information storage, in particular to a method and device for automatically locating memory faults. Background technique [0002] An MCA (Machine Check Architecture) is provided in the Intel CPU. The MCA of the Nehalm platform will record the slot information of the faulty memory in the register, and the application can locate the faulty memory by reading the value in the register . [0003] But once the MCA architecture of the Sandybridge platform changes, the slot information of the faulty memory is no longer directly recorded in the register, so the previous detection method cannot determine the slot of the faulty memory. Summary of the invention [0004] The present invention aims to solve at least one of the above technical problems. [0005] To this end, an object of the present invention is to provide an automatic memory fault location method capable of accurately locating and repairing a faulty memory slo...
