Embodiment Construction

[0012] In order to make the purpose, technical features and implementation effects of the present invention clearer, preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] The device for protecting and restoring computer configuration information adopted in the present invention protects and restores computers with storage devices and independent redundant disk array cards.

[0014] Wherein, the configuration information storage unit in the protection recovery device replaces the hard disk HPA as the second memory, and is used to save the RAID configuration information of the computer and the MBR partition configuration information of the hard disk; the two configuration information stored in the protection recovery device are both is the initial configuration information.

[0015] The protection recovery device can be realized by using different components, and is used t...

Abstract

The invention provides a device, a computer and a method for protecting and restoring an operating system; wherein, the device is applied to a computer which is provided with a memory equipment and independent redundant disk array card, and at least comprises a configuration information memory unit, a calibrating unit and a restoring unit; the configuration information memory unit is used for storing the initial independent redundant disk array configuration information and the initial master boot record partitioning configuration information, the calibrating unit is used for comparing the initial independent redundant disk array configuration information with the current independent redundant disk array configuration information, and the initial master boot record partitioning configuration information with the current master boot record partitioning configuration information, and for generating a restoring command if the comparison result is inconsistent, and the restoring unit is used for restoring the current independent redundant disk array configuration information and the current master boot record partitioning configuration information. With the adoption of the technology provided by the above preferential embodiment of the invention, under the circumstance that HPA of the memory system configuration is damaged, RAID card configuration information and hard disk MBR partitioning configuration information can be still guaranteed simultaneously, thus ensuring the next normal starting of the operating system.

Description

technical field [0001] The invention relates to computer system maintenance technology, in particular to a device, computer and method for protecting and restoring computer configuration information. Background technique [0002] Computer systems, especially server systems therein, generally have a redundant array of independent disks (RAID, Redundant Array of Independent Disk) configuration, and the RAID configuration information is stored on the RAID card and hard disk; When initializing the RAID card, long-term detection and verification must be carried out to ensure that the status of the RAID card is normal and the stored RAID configuration information is not damaged; at the same time, it must be ensured that the MBR partition in the hard disk's Master Boot Record (MBR, Master Boot Record) partition Only when the configuration information is completely correct can the operating system be started smoothly. Once the RAID configuration information or the MBR partition con...
