Problems solved by technology

However, when system switching is performed, maintenance personnel are usually required to operate through the mouse, keyboard and monitor, so the above-mentioned IO peripherals need to be configured in RAID, which will increase the cost and increase the workload of maintenance personnel.

Embodiment Construction

[0014] The basic idea of ​​the operating system recovery method of the disk array proposed by this application is: set an extra storage disk in the RAID as a system backup disk, and install a backup operating system in the system backup disk. power state; when the main operating system in the RAID crashes, connect the circuit board through the panel switch to power on the system backup disk, start the operating system in the system backup disk, and use the general hardware system conversion tool (GHOST, General Hardware Oriented System The pload parameter in the Transfer) command automatically restores the backup RAID main operating system, and an alarm sound is issued to inform the user that the restoration is complete, and then the user restarts the RAID and SATA disks through the panel switch button to power off and enter the RAID main system. In the whole process, no mouse, keyboard and monitor are needed, and the main system that cannot be started can be recovered by switc...

Abstract

The invention discloses a method for recovering an operating system of a RAID (Redundant Array of Independent Disk). The method comprises the steps of: connecting a panel switch with a circuit board to switch on and switch off electricity of a back-up disk of the system at the absence of a mouse, a keyboard and a display; starting up a standby operating system in the back-up disk of the system when the electricity of the back-up disk of the system is switched on; recovering the back-up RAID operating system automatically through pload parameters in a GHOST (Global Horizontal Sounding Technique) command; giving an alarm to inform a user that the recovery is finished; and then restarting and switching off the back-up disk of the system by the user to enter into an RAID main operating system. The mouse, the keyboard and the display are unnecessary during the whole process; and the corrupted main operating system can be recovered through a switch button.

Description

technical field [0001] The present application relates to the technical field of disk arrays, in particular to a method for recovering an operating system of a redundant array of independent disks (RAID, Redundant Array of Independent Disk). Background technique [0002] RAID is a redundant array composed of multiple cheap disks, which appears as an independent large storage device under the operating system. RAID can give full play to the advantages of multiple hard disks, improve the speed of hard disks, increase capacity, and provide fault tolerance to ensure data security. Affected by a damaged hard drive. Currently there are several mainstream RAID levels such as RAID0, RAID1, RAID5, RAID6, and RAID10. [0003] Because RAID usually needs to be turned on for a long time, it is inevitable that the operating system will crash. The countermeasure that is often adopted in the prior art is to set two primary partitions on the system disk, and install an operating system on...
