Detailed Description
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 only a part of the embodiments of the present application, and not all of the 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 embodiment of the application discloses a hard disk control method, which realizes information access when a hard disk is locked.
Referring to fig. 1, a flowchart of a hard disk control method according to an exemplary embodiment is shown, as shown in fig. 1, including:
s101: determining a currently accessed target hard disk and acquiring a disk identifier of the target hard disk;
the execution subject of this embodiment may be a server, and the purpose is to control a hard disk connected to the server. In this step, a target hard disk intervening in the server is first determined, and a drive letter of the target hard disk is acquired.
Specifically, hdparm (hard disk parameters) tools can be adopted, that is, the steps include: determining a currently accessed target hard disk by using an Isscsi (Chinese full name: Small Computer system interface, English full name: Internet Small Computer System interface) command, and recording hard disk information of the target hard disk into a target temporary file; and acquiring the drive letter of the target hard disk from the target temporary file. In the specific implementation, firstly, an lsscsi command is adopted to scan a target hard disk accessed on a current server, and hard disk information is recorded in a temporary file, wherein the hard disk information comprises a drive letter of the hard disk. Then, the hard disk drive letter is acquired from the temporary file.
It should be noted that the triggering manner of this step is not limited here, and the step may be automatically triggered when the server is powered on, and the step in this embodiment is written as a script and placed in the server system file/etc/rc.d/rc.local, so as to implement automatic detection of the locked state of the hard disk and automatic unlocking when the server is powered on. Namely, the method comprises the following steps: when the server is started, determining a currently accessed target hard disk, and acquiring a disk identifier of the target hard disk. Of course, the trigger may be triggered after receiving the command of the user, and both are within the protection scope of the present embodiment.
S102: acquiring the hard disk state of the target hard disk by using a first target command according to the disk identifier;
in this step, a first target command is used to obtain a hard disk state of a target hard disk, where the hard disk state includes a locked state and an unlocked state, and the hard disk in the locked state cannot perform information access operation on the hard disk. The first target command in this step is specifically: the hdparm-I/dev/sdx, sdx is the disk symbol of the hard disk.
S103: and if the hard disk state is the locked state, unlocking the target hard disk in the locked state by using a second target command.
Since the hard disk in the locked state cannot perform information access operation on the hard disk, the hard disk in the locked state needs to be unlocked, that is, the target hard disk in the locked state is unlocked by using the second target command. The second target command in this step is specifically: hdparm-user-master u-security-unlock password/dev/sdx.
On the basis of the above embodiment, as a preferred implementation, the method further includes: acquiring the enabling state of the hard disk security mode of the target hard disk by utilizing the first target command according to the drive letter; and if the enabling state is open, enabling the hard disk security mode by using a third target command.
In a specific implementation, the first target command may be further used to obtain an enable state of the hard disk security mode of the target hard disk. If the enable state is open, the information access operation cannot be performed on the enable state, and the next system reboot may cause the target hard disk to be in a locked state, so that a third target command needs to be used to perform a disable operation on the hard disk security mode of the target hard disk. The third target command here is specifically hdparm-user-master u-security-disable password dev/sdx.
Therefore, the hard disk control method provided by the embodiment of the application realizes automatic detection of the locking state of the hard disk and automatic unlocking, effectively avoids the problem that information cannot be accessed due to misoperation of the hard disk, and improves the stability of the storage server and the user experience.
The embodiment of the application discloses a hard disk control method, and compared with the previous embodiment, the embodiment further explains and optimizes the technical scheme. Specifically, the method comprises the following steps:
referring to fig. 2, a flowchart of another hard disk control method according to an exemplary embodiment is shown, and as shown in fig. 2, includes:
s201: when the server is started, determining a currently accessed target hard disk by using an Isscsi command, and recording the hard disk information of the target hard disk into a target temporary file;
s202: acquiring the disk identifier of the target hard disk from the target temporary file;
s203: acquiring the hard disk state of the target hard disk by using a first target command according to the disk identifier;
s204: and if the hard disk state is the locked state, unlocking the target hard disk in the locked state by using a second target command.
S205: acquiring the enabling state of the hard disk security mode of the target hard disk by utilizing the first target command according to the drive letter;
s206: and if the enabling state is open, enabling the hard disk security mode by using a third target command.
Therefore, in the embodiment, the hdparm tool is used for detecting the locking state of the hard disk, and if the hard disk is detected to be locked, the hapram tool is used for unlocking the hard disk, so that the hard disk information access failure is avoided.
In the following, a hard disk control device provided in an embodiment of the present application is introduced, and a hard disk control device described below and a hard disk control method described above may be referred to each other.

Therefore, the hard disk control device provided by the embodiment of the application realizes automatic detection of the locking state of the hard disk and automatic unlocking, effectively avoids the problem that information cannot be accessed due to misoperation of the hard disk, and improves the stability of the storage server and the user experience.
On the basis of the foregoing embodiment, as a preferred implementation, the determining module 301 includes:
the determining unit is used for determining a currently accessed target hard disk by using an Isscsi command and recording the hard disk information of the target hard disk into a target temporary file;
