Embodiment Construction

[0086] Each of the disks is connected to the physical port of the SAS expander, and each of the SAS expanders is connected to the physical port of the SAS card;

[0087] like figure 1 As shown, a configuration method of a disk array device, the specific steps are:

[0088] Step 1, in the Linux operating system, use the RAID tool operation command to create a redundant array of independent disks;

[0089] Step 2, obtaining the physical port identification number SASPHY ID of each of the disks in the redundant array of independent disks, the process is:

[0090] Step 2-1, search for the kernel information under the system folder directory in the operating system, and obtain from the kernel information:

[0091] 1) SAS card number;

[0092] 2) The serial number of the SAS expander;

[0093] 3) The number of the physical port connected to the disk in the SAS expander;

[0094] Step 2-2, obtain the physical port identification number SAS PHY ID of each described disk by the s...

Abstract

The invention relates to an RAID (redundant array of independent disks) equipment configuration method, an RAID equipment assembly method and an RAID equipment disk insertion processing method. The configuration method includes: creating an RAID, extracting physical port identifiers corresponding to disks in the RAID, and gathering the physical port identifiers to generate a configuration file. Physical ports are SAS extender physical ports or SAS card physical ports. When a system reboots or disk letters change, the RAID is assembled through the configuration file; when a disk insertion event occurs, the disks are inserted through the configuration file. The process of assembling the RAID or processing disk insertion events is only related to external physical port identifiers or serial numbers and not related to disk letters or information stored in the disks; processing or configuring the information stored in the disks is not required anymore; operational stability of the RAID equipment is greatly improved.

Description

technical field [0001] The invention belongs to a data processing method in the technical field of mass storage, and in particular relates to a configuration method of a disk array device, an assembly method and a disk insertion processing method. Background technique [0002] Redundant Array of Independent Disks (Redundant Array of Independent Disks), referred to as RAID, refers to a logical disk formed by combining multiple independent physical disks in different ways. [0003] At present, the existing technology generally assembles RAID according to the disk drive letter information or processes disk insertion events according to the information stored on the disk; [0004] The specific process of assembling RAID or handling disk insertion events according to the information of the disk drive letter is: [0005] Pre-configure the RAID configuration file mdadm.conf containing the drive letter. The content of the configuration file is as follows: [0006] DEVICE / dev / sd[de...
