Detailed Description
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.
The locking disk is to restrict all disks from being used on the storage system, only those disks passing through the disk locking restriction function can be used on the storage device, and the disks not passing through are not identified and cannot be used. The existing storage equipment has the problem of compatibility of an old disk when the version of a locked disk is upgraded. Since the old disk does not support the acquisition of some commands or some contents and there is no encrypted data on the old disk, the problem arises after the upgrade.
Based on the above technical problem, this embodiment provides a method for upgrading a locking disk, including obtaining disk identifiers of all disks of a storage system;
determining a disk to be written in from all disks according to the disk identification, and writing encrypted data in the disk to be written;
when the locking disc version is upgraded, decrypting the encrypted data of the disc in the upgraded storage system;
when the decryption is successful, the disk which is successfully decrypted is online; and if the decryption fails, the off-line decryption fails.
Therefore, the disk identification of each disk of the storage system is obtained before upgrading, the disk to be written is determined according to the disk identification, the disk to be written is not encrypted and is an old disk, the encrypted data is injected into the old disk, and the encrypted data of the disk is decrypted after upgrading is completed, so that the old disk originally inserted into the system can be continuously used, the compatibility of the disks is realized, the upgrading is ensured to be smoothly carried out, and the user experience is improved.
Referring to fig. 1 specifically, fig. 1 is a flowchart of a lock disc upgrading method provided in an embodiment of the present application, which specifically includes:
s101, acquiring disk identifications of all disks of a storage system;
the storage system comprises a plurality of magnetic disks, and the plurality of magnetic disks can be all old disks; all are new discs; a part of old disc and a part of new disc; wherein, the new disc refers to a magnetic disc capable of supporting the setting function, and the old disc cannot support the setting function. Wherein the disk identification includes, but is not limited to, a date of manufacture or a functional parameter or disk ID.
S102, determining a disk to be written in from all disks according to the disk identification, and writing encrypted data in the disk to be written in;
in this embodiment, the disk to be written is determined from all the disks according to the disk identifier, and it can be understood that different disk identifiers are determined in different manners. After the disk to be written is determined, a section of blank sector is reserved on the disk to be written, and encryption processing is performed on the disk to be written, namely, encrypted data is injected into a fixed position of the disk to be written.
In an implementation manner, the first target disk of the production log before the preset date is an old disk, that is, a disk to be written, and there is no encrypted data in the disk to be written, and at this time, the production date is used as a disk identifier, and it can be understood that the newer the production date is, the more complete the function of the disk is. Wherein the preset date is the date of the upgraded version of the lock disc.
In another implementation, the first target disk without the setting function is an old disk, that is, a disk to be written, where there is no encrypted data in the disk to be written, and at this time, the disk identifier is a function parameter of the disk, that is, a supported command, for example, the disk 1 has a function a; the magnetic disk 2 has functions a, b; the magnetic disk 3 has a function a; the disk 4 has functions a, b; when the functions are set as functions a and b, the magnetic disk 1 and the magnetic disk 3 are old disks, namely, magnetic disks to be written, and the magnetic disk 2 and the magnetic disk 4 are new disks. The function parameter is the function parameter of the disk of the date corresponding to the lock disk upgrading version.
In another implementation, the disk identifier may also be a set ID, and when the ID is set, the setting may be performed according to a production sequence, that is, the disk with the set ID within the target ID range is used as a legacy disk, that is, a disk to be written, where there is no encrypted data in the disk to be written; for example, the ID of disk 1 is 1, and the ID of disk 2 is 2; the ID of the disk n is n. The set ID is the ID corresponding to the lock disc upgrading version.
Of course, other forms may also exist, the present embodiment is not limited, and as long as the purpose of the present embodiment can be achieved, the user may customize the setting.
In this embodiment, after the disk to be written is determined, since the new disk supports some commands, some contents are acquired, and there is encrypted data, the disk to be written does not support some commands, some contents are acquired, and there is no encrypted data in the old disk, if the disk locking upgrade is directly performed, the problem of an upgrade failure may occur.
S103, after the version of the locking disk is upgraded, decrypting the encrypted data of the disk in the upgraded storage system;
and after upgrading the lock disk version, decrypting the disk in the storage system.
Further, the disks in the upgraded storage system include a disk before upgrading and a newly inserted disk.
At this time, the disk in the storage system after being upgraded has two situations, the first situation is that the disk before being upgraded is on the storage system, and the second situation is that the disk newly inserted is on the storage system, and the newly inserted disk may be a new disk or an old disk.
After the version of the lock disk is upgraded, the encrypted data exists in the new disk, and the encrypted data is written into the disk to be written, so that the encrypted data of the new disk and the encrypted data of the disk to be written can be decrypted.
But when there is a newly inserted disk, if the newly inserted disk is a new disk, the new disk itself has encrypted data, and therefore decryption of the encrypted data of the newly inserted disk can be performed; if the newly inserted disk is an old disk, when the encrypted data is written in the old disk, decrypting the encrypted data of the newly inserted disk can be executed; if the newly inserted disk is a legacy disk, the decryption cannot be performed when the legacy disk is not written with encrypted data.
S104, when the decryption is successful, the disk which is successfully decrypted is online; and if the decryption fails, the off-line decryption fails.
After decryption succeeds, the successfully decrypted disk can be normally used, and therefore the successfully decrypted disk is on-line; and if the decryption fails, the disk with the decryption failure cannot be used, and the disk is kicked.
Based on the technical scheme, the disk identification of each disk of the storage system is obtained before the upgrade, the disk to be written is determined according to the disk identification, the disk to be written is not an old disk, the encrypted data is injected into the old disk at the moment, and the encrypted data of the disk is decrypted after the upgrade is completed, so that the old disk originally inserted in the system can be continuously used, the compatibility of the disks is realized, the upgrade is ensured to be smoothly carried out, and the user experience is improved.
In an implementation manner, in order to quickly determine the disk to be written, in this embodiment, the disk identifier is set to a production date, and specifically, when the disk identifier is the production date, acquiring the disk identifiers of all the disks of the storage system includes:
acquiring production dates of all disks of the storage system;
correspondingly, determining the disk to be written in from all the disks according to the disk identifier, including:
and taking the first target disk with the production date between the preset dates as the disk to be written.
In this embodiment, a first target disk of a production log before a preset date is an old disk, that is, a disk to be written, and the disk to be written does not have encrypted data.
Therefore, the method and the device can quickly determine the disk to be written by taking the production date as the disk identifier, and improve the determination efficiency of the disk to be written.
Further, after the disk to be written is determined, whether the disk to be written has the encrypted data or not is judged, if yes, the encrypted data is not written again, and if not, the encrypted data is written, so that the situations of resource waste and complex operation caused by repeated writing are ensured.
Further, there may be a second target disk that cannot acquire a disk identifier, and in this embodiment, the disk is also used as a disk to be written, so that the occurrence of missing determination by an old disk is avoided, and specifically, the method further includes: and determining the second target disk which does not acquire the production date as the disk to be written.
In this embodiment, the second target disk of the production date that is not obtained is also used as the disk to be written, and at this time, the disk to be written includes: a first target disk and a second target disk.
Therefore, in the embodiment, the disk which does not acquire the production date is also used as the disk to be written, so that the situation that the old disk is determined to be missing is avoided.
Further, this embodiment may further include: after the first target disk and the second target disk are determined, whether the first target disk and the second target disk have the encrypted data or not is judged, if the first target disk and/or the second target disk have the encrypted data, the encrypted data is not written again, and if the first target disk and/or the second target disk do not have the encrypted data, the encrypted data is written, so that the situation that repeated writing is not performed, resource waste is caused, and the operation is complicated is ensured.
Further, the obtaining of the production date is further explained, wherein the obtaining of the production dates of all the disks of the storage system comprises:
issuing a date acquisition instruction to each disk to obtain feedback information of each disk;
judging whether the byte length of the feedback information is greater than or equal to a preset length or not;
and if the length is larger than or equal to the preset length, acquiring the production date.
Specifically, the code implements a lock disk upgrade module that is executed first when the upgrade is initiated.
In an implementation real-time manner, the date acquisition command inquiry std may be issued to all the disks to obtain feedback information of each disk, and whether the length of the response (feedback information) is greater than or equal to a preset length (e.g. 106 bytes) is determined, and if the length is greater than or equal to the preset length, the production date is acquired from 102 bytes and 106 bytes.
Further, if the length is smaller than the preset length, the disc can be determined as an old disc; or if the length is smaller than the preset length, a log sense command can be issued, the command is used for acquiring the production date, whether the command is supported by the state given by the response message is judged, and if the command is not supported, the disk is identified as an old disk.
In another real-time implementation mode, a log sense command is issued, the command is used for acquiring the production date, whether the state given by the response message supports the command is judged, and if not, the disk is identified as an old disk.
Further, when the disk identifier is a supported command, acquiring disk identifiers of all disks of the storage system, including:
acquiring a command supported by each disk;
correspondingly, determining the disk to be written in from all the disks according to the disk identifier, including:
and determining the disk of the supported commands, which comprises the preset commands, as the disk to be written.
Further, when the disk identifier is the set ID, acquiring the disk identifiers of all the disks of the storage system includes:
acquiring a set ID of each disk;
correspondingly, determining the disk to be written in from all the disks according to the disk identifier, including:
and taking the third target disk with the set ID in the target ID range as the disk to be written.
The disk identification can also be a set ID, and the ID can be set according to the production sequence when being set, namely, the disk with the set ID in the target ID range is used as a master disk, namely, the disk to be written, and the disk to be written has no encrypted data; for example, the ID of disk 1 is 1, and the ID of disk 2 is 2; the ID of the disk n is n.
Based on any embodiment, the invention realizes an implementation mode of the lock disk upgrading function on the storage system, is compatible with all the old disks originally inserted into the storage system, and does not support the old disks to be replaced by other old disks. Restricting them from buying new encrypted discs. The embodiment provides a specific locking disc method, which comprises the following steps:
1. the code implements a lock disk upgrade module that is executed first at the beginning of the upgrade. And for all the disks, issuing a date acquisition instruction inquiry std, judging whether the response length of the feedback information of each disk is 106 bytes, and if so, acquiring the production date from 102 and 106 bytes. Otherwise, sending log sense command, judging whether the state given by the response message supports the command, if not, marking the disk as a disk to be written, namely an old disk.
2. On the storage system, an encryption module is added before upgrading, all the old disks are traversed, a section of blank sectors is reserved on the old disks, encryption processing is carried out on the old disks, and encryption data are injected into fixed positions of the old disks.
3. After upgrading, when the lock disc is processed, the decryption is directly carried out, and if the decryption fails, the lock disc is kicked. The decryption is successful and the disc is made online and available.
In summary, before upgrading, production dates are acquired for all disks on the storage system, if the production dates are not acquired, encrypted data are injected into the disks, or when the disks are determined to be old disks according to the production dates, the encrypted data are injected; after upgrading, when the disc is locked, if the production date does not exist (the disc is a old disc), the disc is directly decrypted, and the old disc can be used after the decryption is successful. The specific implementation is that before upgrading, a command for locking disks is issued to all disks on a storage system, the production date is obtained, and if some old disks are not obtained, encrypted data are injected into the disks. After upgrading, when the lock disc is judged, if the production date does not exist, the decryption is directly carried out, and because the encrypted data is injected previously, the decryption is successful, and the old disc can be used. After upgrading, for other old discs inserted by the user, the user cannot use the old discs because the user does not acquire the production date and fails to decrypt because the user does not inject the encrypted data in advance. This limits the user to use all the old disks inserted in the storage system at that time, or to buy new encrypted disks, and not to insert other old disks.
