Embodiment
In order to solve the problem cannot known in time when breaking down in operating system installation process existed in prior art, existing operating system installation process is conducted in-depth research.
The operating system installation deployment way of extensive mainframe cluster Major Epidemic has many forms, such as mirror image forms and configuration file form etc. at present, wherein:
Mirror image forms: make mirror image with the main frame having installed operating system, directly by network by image copying on destination host.
Configuration file form: by the configuration file file designated mounting flow process write, selected installation kit, setting Installation Options etc., simulate manual operating system installation process, by network read operation system fixing disc, and according to the step preset, complete operation system is installed step by step.
Although these two kinds of forms above-mentioned phenomenologically have larger difference, but main actualizing technology is all based on PXE system, as shown in Figure 1, for the operating system installation process implementation schematic diagram of mainframe cluster extensive in prior art, wherein, arrange PXE server in local area network (LAN) inside, in extensive mainframe cluster, all destination hosts are that netboot starts.DHCP request bag can be sent on network after destination host starts, this request can be replied after PXE server receives this request bag, distributing IP address is to destination host, and destination host is then downloaded one by TFTP or MTFTP from PXE server and started software kit to local memory and perform.To start after software kit and can will read Clone mirror picture or operating system installation bag to this locality from PXE server end according to the step preset.After startup software kit runs startup, destination host and PXE server enter automatic interaction state, at this moment just cannot obtain operating system installation state, only after operating system installation completes, just can obtain operating system installation successful result.
As shown in Figure 2, that installs for the destination host complete operation system in mainframe cluster extensive in prior art realizes schematic diagram, mainly be divided into three phases, first stage is IPMI (IntelligentPlatform Management Interface, IPMI) host service function process, this process can obtain current state by IPMI instrument return value; Second stage is that PXE guides start-up course, and this process can obtain current state by the daily record of PXE server end; Phase III is operating system installation process, known by above-mentioned analysis, and the various progress status in this process and error situation all cannot long-rangely obtain, and namely enter black box state.
For individual host, the installation of complete operation system will expend the time that tens arrive dozens of minutes usually, mainly depending on host hardware performance and wideband condition.If the situation of a large amount of concurrent installation of main frame, this time loss also likely has a certain amount of prolongation.As the long operation that such time span is very large, cannot obtain state feedback directly in real time in operation implementation, this will inevitably cause operating efficiency to decline to a great extent.
In addition, have the environment of a large amount of main frame at extensive mainframe cluster under, the health state of hardware of main frame cannot ensure often completely, especially in a large amount of long playing hardware environment.The fault detect instrument of the prosthetic intervention of a lot of main flow also all depends on operating system at present.Under this kind of circumstances and condition, the fault detect of automation operating system installation procedure hinders the development of large-scale cluster automatic management.
Based on the defect that aforesaid operations system installation process exists, the present invention proposes a kind of failure detection schemes, in conjunction with current IMAQ and correlation technique, PXE system is improved.In this technical scheme, by obtaining the screen picture of the destination host be in operating system installation process, and according to the displaying contents of screen picture obtained, determine the installment state of the operating system of destination host, when the installment state determined is for time abnormal, export for pointing out current operation system to install abnormal alarm information, compared with prior art, when breaking down in operating system installation process, exception can be judged fast according to the displaying contents of current screen image, and initiatively go to confirm fault without the need to artificial, thus the judgement time shortened fault, improve the Fault Identification efficiency in extensive mainframe cluster operating system installation process.

Optionally, for the problem that cannot obtain the real-time status in operating system installation process in prior art, as shown in Figure 4, be the specific implementation flow chart of a kind of fault detection method that the embodiment of the present invention provides.
Step 41, is in the screen picture in operating system installation process by IPMI acquisition destination host;
Step 42, according to the displaying contents of the screen picture obtained, determines the installment state of the operating system of above-mentioned destination host;
Step 43, when the installment state determined is for time abnormal, exports for pointing out current operation system to install abnormal alarm information;
Wherein, the specific implementation of step 41 ~ 43 with reference to above-described embodiment, can not repeat them here.
Step 44, when the installment state determined is normal, contrasts the screen picture of acquisition and the stage diagram picture corresponding respectively with each erection stage in operating system installation process prestored;
Wherein, the stage diagram picture that each erection stage (such as format, installation kit initialization, file copy and software kit installation etc.) in operating system installation process is corresponding can obtain in advance and store.
Step 45, according to comparing result, determines the current residing erection stage of the operating system of above-mentioned destination host;
Step 46, exports the notification message of the current residing erection stage of operating system for characterizing above-mentioned destination host.
By above-mentioned steps 45-46, staff can be made to know the current residing erection stage of operating system in real time, thus have understanding roughly to installation progress.
In the embodiment of the present invention, by obtaining the screen picture being in destination host in operating system installation process, and according to the displaying contents of the screen picture obtained, determine the installment state of the operating system of destination host.When the installment state determined is for time abnormal, export for pointing out current operation system to install abnormal alarm information, compared with prior art, when breaking down in operating system installation process, exception can be judged fast according to the displaying contents of screen picture, and without the need to artificially initiatively confirming fault, thus shorten the judgement time to fault, improve the Fault Identification efficiency in extensive mainframe cluster operating system installation process;
When the installment state determined is normal, the current residing erection stage of operating system can be determined further and report, achieve and the refinement of operating system installation process is monitored, improve the controllability of extensive mainframe cluster operating system installation process, also simplify the management process of staff.
