Detailed Description
The core of the application is to provide a method, a system, equipment and a computer readable storage medium for hard disk identification, which are used for preventing a user from replacing a hard disk provided by a non-server/storage manufacturer by himself.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
For the server/storage device, it is required to have good reliability because the loss and cost of data loss, shutdown and line stop caused by hard disk failure are huge, and the maintenance cost is high, so the hard disk used by the server/storage device is generally an industrial hard disk, and the stability and reliability of the industrial hard disk are much higher than those of a consumer hard disk.
However, for the user, considering the cost or data transfer, the hard disk provided by the server/storage manufacturer may be replaced by the consumer hard disk by himself, which causes the reliability of the server/storage device to be reduced and even brings huge loss and cost, and based on this, the present application provides a method for identifying the hard disk, which is used for solving the above problems.
Referring to fig. 1, fig. 1 is a flowchart of a hard disk identification method according to an embodiment of the present disclosure.
The method specifically comprises the following steps:
s101: when the equipment is powered on and started or the hard disk is inserted into the equipment, reading the unique identifier of the hard disk;
the unique identifier of the hard disk mentioned herein may specifically include, but is not limited to, at least one of a hard disk ID, an SN code, and a PN code.
S102: judging whether a ciphertext exists in a reserved area of the hard disk;
if yes, go to step S103;
optionally, when the cipher text is not stored in the reserved area of the hard disk, it is proved that the hard disk is not a hard disk provided by a server/storage manufacturer, and a consumer-grade hard disk replaced by a user with a high probability is provided, and at this time, the hard disk can be prohibited from being used, so as to further avoid the problem of reliability reduction of the server/storage device, and reduce the probability of occurrence of huge loss.
S103: reading the ciphertext, and decrypting the ciphertext into a plaintext by combining a preset key;
optionally, the ciphertext mentioned here is obtained by encrypting the unique identifier in combination with a preset key, and the ciphertext is set for the hard disk meeting the requirement in advance, so that the hard disk can be used by the device, where the process of setting the ciphertext for the hard disk in advance mentioned here may specifically be:
determining the level of the hard disk according to the input customization requirement;
encrypting the unique identifier of the hard disk by using the secret key corresponding to the hard disk level to obtain a ciphertext;
and writing the cipher text into the reserved area of the hard disk.
The encryption mentioned here may be encryption according to a preset symmetric encryption algorithm, which may include but is not limited to at least one of AES encryption algorithm, DES encryption algorithm, SM4 encryption algorithm, and the server/storage vendor may select according to the actual production environment;
when the reserved area of the hard disk has the ciphertext, the hard disk is indicated to be a hard disk provided by a server/storage manufacturer possibly, the ciphertext is read at the moment, and the ciphertext is decrypted into a plaintext by combining a preset key, so that whether the hard disk is the hard disk provided by the server/storage manufacturer is judged by judging whether the plaintext is the same as the unique identifier;
optionally, the ciphertext is decrypted into a plaintext by combining with a preset key, where the preset key may specifically be a key set by a server/storage manufacturer according to conditions such as a production environment, or may also be a key acquired by logging in a preset website by a system.
S104: judging whether the plaintext is the same as the unique identifier;
if not, the step S105 is executed;
when the plaintext is different from the unique identifier, the plaintext indicates that the hard disk and the device may not be manufactured by the same server/storage manufacturer, or the hard disk and the device belong to different grades, that is, the hard disk does not meet the requirements of the device, and the hard disk is forbidden at this moment;
optionally, when the plaintext is the same as the unique identifier, the hard disk can be normally used
S105: the hard disk is prohibited from being used.
Preferably, after the hard disk is forbidden to be used, prompt information that the hard disk does not meet the standard can be output, so that a user can replace the hard disk meeting the requirement in time.
Based on the technical scheme, the method for identifying the hard disk, provided by the application, has the advantages that the cipher text is preset for the hard disk, so that when equipment is powered on and started or the hard disk is inserted into the equipment, the unique identifier of the hard disk is read, and whether the cipher text exists in the reserved area of the hard disk or not is judged; if so, reading the ciphertext, and decrypting the ciphertext into a plaintext by combining a preset key; judging whether the plaintext is the same as the unique identifier; if the plaintext is different from the unique identifier, the hard disk is forbidden to be used, so that the risk that a user replaces the hard disk provided by a non-server/storage manufacturer by himself is avoided, the problem that the reliability of the server/storage equipment is reduced is further avoided, and the probability of huge loss is reduced.
For the step S103 of the previous embodiment, the ciphertext is decrypted into a plaintext by combining with the preset key, and specifically, the corresponding key may also be selected according to the device level of the current device, which is described below with reference to fig. 2.

the device classes referred to herein may be specifically classified as low-end, medium-end, high-end devices.
S202: searching a key corresponding to the equipment level in a preset key table;
s203: the cipher text is decrypted into plaintext in combination with the key.
The equipment level can be divided according to the application environment and the equipment attribute of the equipment, and the equipment in different levels has different requirements on the rotating speed, the medium and the interface type of the hard disk, so that when the cipher text is set for the hard disk, the hard disks with different attributes can be encrypted by different secret keys, and based on the cipher text encryption method, when the cipher text is decrypted into the plaintext by combining with the preset secret key, the equipment level of the current equipment is firstly obtained; then, a secret key corresponding to the equipment level is searched in a preset secret key table; and finally, the cipher text is decrypted into a plaintext by combining the key, and the decryption of the cipher text is completed.
