All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that, in the description of the present invention,
DIMM (Dual-Inline-Memory-Modules) is a Dual Inline Memory module;
the CPU (Central Processing Unit) is a Central Processing Unit.
Example 1
Referring to fig. 1, an automatic system for memory fault injection according to the present invention includes: the device comprises a memory information acquisition module, an error injection module and an interfacing module;
because the implementation of the embodiment is based on the python language, some python native library functions are adopted to implement the functions of the whole automation system.
The memory information acquisition module takes a dimminfo function as a main function for realizing functions, can acquire the in-place conditions of memory banks of all DIMM slots of the server to be tested, such as the position information of the memory banks, including CPU data, slot numbers, channel numbers and the like of the memory, and can also acquire the model information of the memory banks, such as manufacturers of the memory banks, the capacity of the memory, the working frequency of the memory and the like, and sends a plurality of information acquisition instructions to the memory banks, and acquires memory card information corresponding to the information acquisition instructions according to return values.
The fault injection module takes an injectMemError function as a main function for realizing functions, parameters in the injectMemError function comprise a socket word, a channel number, a DIMM slot number, a grade and an error type, the parameters are filled in the fault injection module, errors can be specified to be injected into a memory, for example, ce or uce is input into the error type parameter, recoverable errors or unrecoverable errors can be injected into a memory bank, after the injectMemError function injects errors into the memory card, the return value of the function is a fault injection result, because the DIMM is a dual in-line slot, the slot number of the dual in-line SIMM slot can be obtained according to the same mode.
The interface module uses a series of original library functions of python, and a graphical interface can be quickly and conveniently created through the library functions, because the existing client script is operated by a command line, most of server maintenance personnel who are not familiar with the language of the command line cannot conveniently operate, the graphical interface is adopted in the embodiment, so that the server maintenance personnel can obtain a friendly interface, and therefore, on the graphical interface, the position information and the model information of the memory bank acquired through the memory information acquisition module can be displayed on the graphical interface.
In a graphical interface of the interface module, each in-place memory has an error injection type behind it, and after a server maintainer selects an error injection type, the interface module sends error injection type information to the error injection module, and the error injection module assigns the error injection type to an error type parameter of the injectMemError function.
The interface module is provided with a one-key error injection function, the function is realized by relying on an injectMemError function, when server maintenance personnel need to inject errors into all memory cards in the server, and the types of the errors are uniform, the server maintenance personnel can select one-key error injection, call the injectMemError function through multithreading, and inject the errors into the multiple memory cards.
And after the memory card is subjected to error injection through the injectMemError function, a return value can be obtained, the return value is equivalent to an error injection result, the result is fed back to a graphical interface of the interfacing module, and the result comprises an error injection success number, an error injection failure number and memory position information corresponding to the error injection failure.
Example 2
The embodiment of the present invention provides a method for using a memory error injection automation system, please refer to fig. 2, which includes the following steps:
because the memory information acquisition module, the error injection module and the interface module are integrated, on a graphical interface provided by the interface module, the error injection type of the memory is selected behind the position information of the memory according to the position information of the provided memory, when all the error injection types are uniform, the interface module can call an injectMemError function of the error injection module by multiple lines, a key error injection is selected on the graphical interface, error injection is carried out on all the memories of the server, because the error injection module can obtain a return value after error injection is completed, whether one-key error injection is realized or not is judged on the graphical interface according to the return value, if the number of the error injection success is equal to the number of the memories selected by the user, the error injection success is proved, and if the number of failures exists, the memory is maintained according to the position information of the memory which fails to inject the errors.
If we do not select a key for error injection, the specified memory can be subjected to error injection according to the DIMM slot number and the channel number, whether the error injection is successful or not is judged according to a return value after the error injection is finished, if the error injection is successful, the error injection is finished, and if the error injection is failed, the memory is maintained according to the position information of the memory in which the error injection fails.
