CN103514022A - RAID card drive integration method under LINUX - Google Patents

Abstract

The invention relates to a drive integration method, and discloses an RAID card drive integration method under LINUX. The RAID card drive integration method includes the steps that an original initrd. img file is decompressed to obtain corresponding catalogs and files; a module file driven by an RAID is compressed and placed in a designated catalog; hardware information of an RAID card is added to a designated file; all the modified catalogs and the files are packaged and compressed to obtain the modified initrd. img file with RAID drive; the modified initrd. img file is utilized to replace the original file, an ISO is manufactured and recorded, and then the RAID card can be normally driven after a light disk is installed. The RAID card drive integration method has the advantages that the integration method is relatively simple, the integrated RAID card can be used for PXE network installation and traditional light disk installation, the integration process is flexible and quick, time and labor are saved in the installing process of a large-scale system, and the installing process is safe and stable.

Description

RAID card under a kind of LINUX drives integrated approach

Technical field

The present invention relates to a kind of integrated method that drives, particularly the RAID card based on LINUX drives integrated approach.

Technical background

Modern computer hardware update speed, corresponding hardware can not be supported by original operating system sometimes, if wherein RAID card does not have corresponding driver, system cannot find hard disk, causes system to install.

In the process starting at LINUX, system kernel vmlinuz starts to provide basic-level support after being loaded into internal memory, various modules under the support of kernel, and service etc. is loaded operation.When kernel is not supported RAID card, the kernel access hard disk of just having no idea, also cannot load the file system on hard disk certainly, causes None-identified hard disk in installation process, installs unsuccessfully.

Classic method is to add RAID card to drive source code then to recompilate out a new kernel file kernel to replace original vmlinuz, or manually selects load driver in installation process.But compiling Kernel-Process is comparatively complicated, the method that manual loading drives is loaded down with trivial details in extensive installation, loses time.

Initrd.img file is the image file of a ram disk.Ramdisk is modeled to disk with a part of internal memory, allows operating system access.Ramdisk is that the equipment (/dev/ram0) file system of standard kernel file understanding is also the file system of standard kernel understanding.This ramdisk of kernel loads as root file system and the init file that starts to carry out wherein load various modules, service etc.After some configurations and operation, just can go physical disk to load real root subregion, be again then some configurations etc., finally start successfully.

Summary of the invention

The technical problem to be solved in the present invention is: the object of the invention is for present case, the integrated approach that provides a kind of RAID card to drive, employing simply, method completes integrated that RAID card drives flexibly, make to drive and can be given tacit consent to use in the process of installation system, avoid manual loading to drive or recompilate the complicated processes of kernel.

The technical solution adopted in the present invention is:

Under RAID card drive an integrated approach, comprising: by master initrd.img file decompress(ion), obtain respective directories and file; The module file that RAID is driven compresses, and is put into assigned catalogue; By the hardware information of RAID card, add in the file of appointment; By revising catalogue, file later, all pack, compress, obtain revising the initrd.img file that contains the driving of RAID card later; By revising initrd.img later, replace original document, make ISO imprinting, fixing disc can driven RAID card.

Described method comprises that step is as follows:

1, obtain master initrd.img, this file is arranged in fixing disc or mirror image.

2, with file order, check the compression method of initrd.img.

3, the suffix of initrd.img is changed to suffix corresponding to compression method in step 2.

4, with the corresponding decompress(ion) order of the compression method viewing in step 2, the file after change in step 3 is carried out to decompress(ion).

5, with file order, check the type of resulting initrd file in step 4.

6, with the corresponding command, resulting file in step 4 is carried out to decompress(ion).

7, img file RAID card being driven carries out carry.

8, the module file of driving is compressed with the compression method of gzip.

9, the corresponding relation of RAID card hardware information and the driving of RAID card is joined in modules.alias file.

10, will in step 8, compress driver module file copy later to specified path, if exist file of the same name to carry out overlapping operation

11, by corresponding compression method boil down to initrd file for the All Files of step 6 decompress(ion).

12, with the compression method in step 2, initrd is compressed.

13, by the file amendment after step 12 compression, be initrd.img.

14, initrd.img is replaced to original document, make ISO, imprinting becomes fixing disc.

Beneficial effect of the present invention is:

RAID card provided by the present invention drives integrated approach to have on the basis of classic method and improves and innovation, the invention has the advantages that integrated approach is relatively simple, and can be for PXE network installation after integrated, also can be used for traditional CD installs, integrating process flexibly and fast, both time saving and energy saving in large scale system is installed, safety and stability again.
