The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
Fig. 1 is a flowchart of a method for controlling power on and power off of a server hard disk according to an embodiment of the present invention.
As shown in fig. 1, a method for controlling power on and power off of a hard disk of a server according to an embodiment of the present invention includes:
s101: and receiving the index information of the hard disk to be processed and the processing content of the hard disk to be processed.
Wherein, the processing content is power-on processing or power-off processing.
In practical application, the identification information corresponding to the hard disk of the server includes a slot number of the hard disk, disk identifier information allocated to the hard disk, and the like, one of the identification information is selected as index information of the hard disk, and a calculation rule from the index information of the hard disk to position information of the hard disk is established according to the type of the index information. Furthermore, various types of index information can be selected to respectively establish corresponding calculation rules.
In a specific implementation, step S101 may specifically be to receive, on the user interaction interface, the input index information of the hard disk to be processed and the processing content of the hard disk to be processed. Step S101 may also be implemented by communicating with a hard disk failure monitoring process of the server to obtain index information of a failed hard disk that needs to be powered off, and determining that the processing content is power off processing.

S103: and generating a control command of the hard disk to be processed according to the position information of the hard disk to be processed and the processing content of the hard disk to be processed.
In the prior art, when a user controls the hard disk to power on and power off, the user needs to calculate the location information of the hard disk and edit a control command to control the hard disk to power on and power off, and usually calls an i2c-test tool provided in the BMC to write the control command into a register of a controller corresponding to the hard disk to be processed. In the scheme, a command for calling the i2c-test tool to write the control command of the hard disk to be processed into the controller can be generated according to the position information of the hard disk to be processed and the processing content of the hard disk to be processed, and in this way, the logic in the BMC needs to be changed more, which is more complex to implement.
Therefore, a better implementation is to set up a script outside the BMC for implementing the above steps. For the convenience of implementation, step S103 is specifically:
and generating an IPMI control command of the hard disk to be processed according to the position information of the hard disk to be processed and the processing content of the hard disk to be processed.

The method for controlling the power-on and power-off of the hard disk of the server provided by the embodiment of the invention can be used for controlling the power-on and power-off of the hard disk of the server by presetting the corresponding relation between the type of the index information of the hard disk and the calculation rule, calling a calculation rule according to the type of the index information of the hard disk to be processed, calculating the position information of the hard disk to be processed according to the index information of the hard disk to be processed, generating a control command according to the position information of the hard disk to be processed and the processing content (power-on processing or power-off processing) of the hard disk to be processed, and finally writing the control command into a controller corresponding to the hard disk to be processed according to the position information of the hard disk to be processed, wherein the power-on or power-off control of the hard disk to be processed can be realized by a user only needing to input the index information and the processing content of the hard disk to be processed without complicated calculation, therefore, the operation of the power-on and power-off control of the hard disk is simplified, and the problem of power-on and power-off failure of the hard disk caused by calculation errors of a user is avoided.
Fig. 2 is a flowchart illustrating a specific implementation manner of step S102 in fig. 1 according to an embodiment of the present invention.
On the basis of the above embodiments, the method for controlling power on and power off of a hard disk of a server according to the embodiments of the present invention provides a type of index information of the hard disk, so as to facilitate an explanation of an actual application of the present solution.
In the method for controlling power on and power off of the server hard disk provided by the embodiment of the invention, the index information of the hard disk to be processed is specifically the serial number of the hard disk to be processed in the serial number sequence formed by labeling all the hard disks of the server from small to large according to the back plate, the number of rows on the back plate and the number of columns on the number of rows.
Assuming that the server shares N backplanes, and the hard disk array on each backplane is m rows by N columns, each backplane corresponds to a controller on the I2C bus in the server. Taking the controller as a CPLD as an example, the register data of the CPLD is one byte, i.e., 8 bits, and can control the power on and off of 8 hard disks at most, so that n is less than or equal to 8.
In the embodiment of the present invention, the arrangement numbers of the hard disks are as follows:
1 st backboard:
2, a back plate:
and (3) a back plate:
4, a back plate:
……

s201: and calculating the total number of hard disks in each row in the whole hard disks of the server.
Assuming that the serial number of the hard disks to be processed is k (k is equal to or greater than 1 and equal to or less than m × N), the total number of hard disks in each row in the entire hard disks of the server is ω — N × N according to the above definition.
S202: and calculating a first quotient of the serial number of the hard disk to be processed divided by the total number of the hard disks in each row, and rounding up the first quotient to obtain the row number a of the hard disk to be processed.
Step S202 may be expressed using the formula: a ═ k ÷ ω.
S203: and performing remainder calculation on the serial number of the hard disk to be processed and the total number of the hard disks in each row to obtain the number b of the columns of the hard disks to be processed in the whole hard disk.
Step S203 can be expressed by the formula: b ═ k% ω.
S204: and calculating a second quotient of the number of the columns of the hard disks to be processed in the whole hard disks divided by the number of the columns of the hard disks on each backboard of the server, and rounding up the second quotient to obtain the serial number c of the backboard where the hard disks to be processed are located.
Step S204 can be expressed by the formula: c ═ b ÷ n.
S205: and performing remainder calculation on the number of columns of the hard disks to be processed in the whole hard disks and the number of columns of the hard disks on each backboard of the server to obtain the number d of columns of the hard disks on the backboard.
Step S205 can be expressed by the formula: d ═ b% n.
S206: and taking the number a of the rows of the hard disks to be processed, the serial number c of the back plate where the hard disks to be processed are located and the number d of the columns of the hard disks on the back plate as the position information of the hard disks to be processed.
In the above steps, the order relationship between S202 and S203 may be reversed, and the order relationship between S204 and S205 may be reversed.
On this basis, the step S103 generates a control command for the hard disk to be processed according to the position information of the hard disk to be processed and the processing content of the hard disk to be processed, and specifically includes:
when the processing content is power-on processing, reading first control data in an a-th register of a controller of a c-th backboard of the server, shifting BIT0 of the a-th register by d BITs to the left to obtain second control data, and performing BIT AND operation on the first control data and the second control data to obtain a power-on control command of the hard disk to be processed;
and when the processing content is power-off processing, reading the first control data, shifting the BIT0 of the a-th register to the left by d BITs, inverting the BIT to obtain third control data, and performing BIT AND operation on the first control data and the third control data to obtain a power-off control command of the hard disk to be processed.
In step S104, the control command of the hard disk to be processed is written into the controller corresponding to the hard disk to be processed according to the position information of the hard disk to be processed, which specifically includes:
the control command is written to the a-th register of the controller of the c-th backplane of the server.
On the basis of the embodiment of the present invention, if other arrangement modes or other labeling rules are adopted to set the index information of the hard disk, the calculation rules may be correspondingly set by referring to the modes provided by the embodiment of the present invention, which all belong to the protection scope of the embodiment of the present invention.
