Embodiment 1

[0023] S1. Install the HBA card physically connected to the hard disk into the server system. After installing the OS, check the disk status, as follows 1-1:

[0024]

[0025] 1-1. Check the status of the HBA card directly connected to the hard disk

[0026] S2. The operating system includes / dev / sdb, / dev / sdc, / dev / sdd, / dev / sde, / dev / sdf, / dev / sdg, / dev / sdh in addition to / dev / sda 1pcs system disk , / dev / sdi a total of 8pcs data disk. For example, you want to configure RAID0 for every two disks to provide disk read and write performance.

[0027] Modify the script parameters to implement RAID0 for every 2 disks of 8pcs data disks:

[0028]

[0029]

[0030]

[0031] S3, copy the script to execute the script in the operating system, and the system automatically performs RAID formation and corresponding configuration, as follows 1-2:

[0032]

[0033] 1-2. The operating system automatically performs RAID components and configuration

[0034] S4. Use the df-...

Abstract

The invention discloses a method for automatically achieving HBA card hard disk RAID configuration based on linux. The method for automatically achieving HBA card hard disk RAID configuration based on linux specifically comprises the steps that S1, an HBA card physically connected with a hard disk is installed in a whole server system, and the state of a magnetic disk is checked after OS installation; S2, script parameters are modified, and RAID0 is installed in every two of 8pcs data disks; S3, a script is executed in a script copying operating system, and the system automatically carries out RAID establishing and corresponding configuration; S4, a df-h command and a fdisk-l command are used for confirming that RAID0 is successfully established in the data disks again, and the HBA card is used for successfully establishing RAID0. Multiple hard disks are configured into a logic disk through a magnetic disk management function provided by an operating system, therefore, a data redundancy function is increased, and efficiency and competitive power are improved through automatic script compiling.

Description

technical field [0001] The invention relates to a method for configuring RAID, in particular to a method for automatically realizing the RAID configuration of HBA card hard disks based on linux. Background technique [0002] With the rapid development and wide application of information technology, information technology concepts such as cloud computing and big data emerge in an endless stream, and large-scale data centers are also constantly being built. A large-scale server cluster brings challenges to operation and maintenance personnel. [0003] Among them, the batch configuration of disk arrays (Raid) of servers and other equipment is one of the problems that plague operation and maintenance personnel. [0004] HBA card: Host Bus Adapter (Host Bus Adapter) is a circuit board and (or) integrated circuit adapter that provides IO processing and physical connections in servers and storage devices. HBA cards cannot form RAID arrays at the hardware level. And the formation ...
