Logic heat adds module 202, for after described physical thermal adds end, and automatic centering central processor CUP, and/or internal memory carries out logic heat and adds.
Alternatively, described detection module 201, for utilizing equipment management tool UDEV, detects the CPU newly added, and/or internal memory, comprising: newly add CPU, and/or, internal memory; Newly add CPU described, and/or the physical thermal of internal memory adds in process, trigger and add add event; The CPU newly added is determined by the path of described event, and/or, internal memory.
Technical scheme of the present invention, can realize after physical thermal adds, automatically carrying out logic heat and adding.Improve efficiency.
Fig. 3 is the schematic diagram of a kind of embodiment of the present invention.
With reference to the accompanying drawings, we just once concrete CPU and the automatic heat-transmission of internal memory add process and are described.
Step S301: pull out and jump the physical thermal that cap triggers corresponding CPU and internal memory and add process;
Step S302:CPU and internal memory physical thermal add in process the add event triggering cpu and memory;
Step S303:udevd finger daemon does corresponding process according to self-defining udev rule to the add event of cpu and memory;
Step S304:shell script carries out the hot add operation of logic according to the devpath of event to corresponding cpu and memory.
For step S304, that is, by the path devpath of event, just can determine the CPU that newly adds and, or internal memory.
As described in summary of the invention, the method that a kind of CPU of the present invention and the automatic heat-transmission of internal memory add mainly comprises the following steps: (1) gets out to support the kernel of RAS characteristic and BIOS and configure server make it support the hot plug of CPU and internal memory; (2) prepare the logic heat that shell script realizes CPU and internal memory and add function; (3) prepare a self-defining udev rule file, drop it off/etc/udev/rules.d/ catalogue under; (4) jumping cap is inserted in pin corresponding to node node and makes node node power-off; (5) cpu and memory board are inserted in draw-in groove corresponding to node node; (6) pull out jumping cap, the CPU that node node is corresponding and the automatic heat-transmission of internal memory are added in system.
Get out to support the kernel of RAS characteristic and BIOS and configure server make it support the hot plug of CPU and internal memory
Download one to linux kernel official website and support good kernel to RAS, the patch then stamping oneself also correctly configures compile option makes it support the RAS characteristic of kernel better, and then compiling installation kernel gets out kernel mirror image file; Supporting that the bios program of RAS characteristic is burnt in BIOS, starting server, and BIOS is arranged, making it support the hot plug of CPU and internal memory.
The logic heat that preparation shell script realizes CPU and internal memory adds function,
A newly-built cpu_online.sh file and a mem_online.sh file after entering system, the logic heat that they realize cpu and internal memory respectively adds function.
Prepare a self-defining udev rule file, drop it off/etc/udev/rules.d/ catalogue under, be switched to/etc/udev/rules.d/ catalogue under, a newly-built cpu_mem_online.rules file, file continues to perform cpu_online.sh script after realizing executing the operation of system default to the add event of cpu subsystem; Continue to perform mem_online.sh script after executing the default action of system to the interpolation add event of memory subsystem.
That is, above-mentioned .rules file is exactly rule file, includes program in rule file, wherein a part of program, can regard detection module 201 as,
Above-mentioned .sh script, wherein containing program, wherein some just can be regarded logic heat as and adds module 202,
No matter be CPU, and, or internal memory, be all that relevant .rules file calls .sh file, particularly the detection module 201 in .rules file and the logic heat in .SH file add module in work.
Jumping cap is inserted in pin corresponding to node node and makes node power-off,
Jumping cap is inserted in pin corresponding to CPU and all non-existent node node of internal memory and makes node node power-off.
(5) CPU and memory board are inserted in draw-in groove corresponding to node node
(6) pull out jumping cap, the CPU that node node is corresponding and the automatic heat-transmission of internal memory are added in system.
The present invention mainly utilizes the uevent treatment mechanism of linux kernel, and the automatic heat-transmission being realized CPU and internal memory by the mode of self-defined udev rule file adds function.The present invention mainly comprises the following steps: (1) gets out to support the kernel of RAS characteristic and BIOS and configure server make it support the hot plug of CPU and internal memory; (2) prepare the logic heat that shell script realizes CPU and internal memory and add function; (3) prepare a self-defining udev rule file, drop it off/etc/udev/rules.d/ catalogue under; (4) jumping cap is inserted in pin corresponding to node and makes node node power-off (cpu on this node and internal memory do not exist); (5) cpu and, or memory board is inserted in draw-in groove corresponding to node node; (6) pull out jumping cap, the CPU that node node is corresponding and the automatic heat-transmission of internal memory are added in system.
Node node refers to, the CPU newly added, and, or, internal memory, the circuit unit at place.
The invention has the beneficial effects as follows: the method can add and adds with logic heat by the one-touch physical thermal realizing CPU corresponding to a certain node and internal memory in system operation, eliminate us and go to search the trouble which CPU and memory block added by successful physical thermal, also can avoid some artificial mistakes simultaneously.
The all or part of step that one of ordinary skill in the art will appreciate that in said method is carried out instruction related hardware by program and is completed, and described program can be stored in computer-readable recording medium, as ROM (read-only memory), disk or CD etc.Alternatively, all or part of step of above-described embodiment also can use one or more integrated circuit to realize.Correspondingly, each module/unit in above-described embodiment can adopt the form of hardware to realize, and the form of software function module also can be adopted to realize.The present invention is not restricted to the combination of the hardware and software of any particular form.
