Problems solved by technology

However, in practical applications, considering the overall performance, reliability and other indicators of the product, as well as the fact that a large amount of loss of computer storage system products comes from disks, corresponding quality requirements will be put forward for disks according to different indicators, and computer storage systems will be matched when they leave the factory. "labeled" disks, the device also does not allow intermixing of non-labeled disks
The hard disk required to be used in many computer storage systems is a high-reliability hard disk. If the user purchases an ordinary hard disk by himself, due to the poor anti-vibration performance and high temperature resistance, it will cause frequent link errors and even disk failure.
In addition, even if the user uses a self-purchased high-reliability hard disk, if the model and firmware of the hard disk do not match the SAS (Serial Attached SCSI, Serial Attached Small Computer System Interface) link parameters configured by the computer storage system itself, it will cause a lot of errors. Code and other issues

Embodiment 1

[0077] A disk validity detection method and authentication method provided by the invention are applied to a computer system. figure 1 Shown is a schematic diagram of the computer system structure, the computer storage system includes: disk, disk drive unit, disk management unit, disk intelligent detection unit, RAID (Redundant Arrays of independent Disks, redundant array of independent disks) controller unit, NAS (NetworkAttachedStorage, network attached storage ) controller unit, SAN (StorageAreaNetwork, storage area network) controller unit, magnetic array controller unit.

[0078] Wherein, the disk is a physical disk installed on the storage system as a physical storage medium by the user when using the storage system device, such as a common hard disk or a solid state disk (SSD).

[0079] Disk drive unit. After the disk is connected to the computer storage system, the system needs to use the disk drive unit to control the physical disk and read and write data.

Embodiment 2

[0139] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0140] Such as Figure 6 Shown is a disk certification method of the present invention, such as Figure 6 The method shown includes four steps of reading the disk serial number and capacity information, calculating the disk authentication code, storing the authentication code, and feeding back the disk marking result.

[0141] In step 201, the system obtains the serial number and disk capacity of the disk that has passed the verification through software, and provides necessary parameters for the subsequent generation of the authentication code. If the serial number or disk capacity fails to be obtained, it prompts to mark the disk as failed authentication.

[0142] Step 202, on the basis of the disk serial number and capacity obtained in step 201, the serial number and capacity are combined to generate an authentic...

Embodiment 3

[0151] Such as Figure 8 Shown is the detection method of a kind of disk effectiveness of the present invention, specifically comprises:

[0152] Step 301, obtain the disk serial number and disk capacity, and calculate the disk authentication code of the disk to be identified by using the algorithm described in step 202;

[0153] Step 302, read as Figure 7 The shown disk fixes the authentication information of the two areas, and checks whether the format of the obtained two sets of authentication information is legal.

[0154] Step 303, if only one group of the two groups of authentication information obtained is legal, only extract the authentication code from the legal group of data (if all are legal, then proceed to step 305), the extracted authentication code is the same as the disk authentication code obtained in step 401 to match. If the matching fails, the computer storage system is notified that the disk is an illegal disk and cannot be used.

[0155] Step 304, if...

Abstract

The invention provides a method for detecting the validity of a magnetic disk. The method is applicable to a computer system. The method comprises the following steps: calculating an authentication code of the magnetic disk according to serial number information and capacity information of the magnetic disk; obtaining authentication information of the magnetic disk; and matching the authentication information with the authentication code of the magnetic disk, and judging the validity of the magnetic disk according to the matching result. By means of the scheme, the authentication code of the magnetic disk is added into a reliable magnetic disk authenticated by a manufacturer of a computer storage system; when being operated, the computer storage system can identify whether the magnetic disk passes verification of the manufacture of the computer storage system or not through the authentication code of the magnetic disk; and thus, the security and the reliability are improved.

Description

technical field [0001] The invention relates to the field of computer storage, in particular to a disk validity detection method, an authentication method and a corresponding device. Background technique [0002] As long as the computer storage system products on the market are compatible with the type of disk interface adapted to the product cabinet (box), in principle, any disk can be used. However, in practical applications, considering the overall performance, reliability and other indicators of the product, as well as the fact that a large amount of loss of computer storage system products comes from disks, corresponding quality requirements will be put forward for disks according to different indicators, and computer storage systems will be matched when they leave the factory. "labeled" disks, the device also does not allow intermixing of non-labeled disks. The hard disk required to be used in many computer storage systems is a high-reliability hard disk. If the user ...
