Embodiment 1

[0046] This embodiment 1 provides a method for lighting the backplane of a hard disk in the POST stage, refer to figure 1 , including the following steps:

[0047] In step S100, a control right closing strategy and a control right restoring strategy are set, and the control right of the hard disk backplane lighting control of the CPLD is closed through the control right closing strategy; the control right closing strategy is: sending a command that the volume manager is in a closed state to CPLD.

[0048] Specifically, in the PEI stage in the POST stage, the BIOS sends a command to the BMC that the volume manager of each hard disk port is in the closed state; that is, the value of the register that defines the volume manager to be in the closed state is the closed state value; The closed state value is sent to the BMC; the BMC receives and sends the command that the volume manager of each hard disk port is in the closed state to the CPLD, so that the CPLD cannot obtain the co...

Embodiment 2

[0057] This embodiment 2 provides a lighting system for the hard disk backplane in the POST stage, refer to figure 2 and image 3 , the hard disk backplane lighting system in the POST stage includes: a sending unit, a judging unit and a control unit;

[0058] The sending unit is used to send the status of the volume manager to the CPLD;

[0059] The judging unit is used to judge whether the driver of the volume manager has been loaded; after the driver of the volume manager is loaded, obtain the value of the register, and judge the volume manager according to the value of the register status;

[0060] The control unit is configured to control the hard disk backplane to perform a lighting operation according to the state of the volume manager.

[0061] Preferably, the sending unit includes a first sending subunit and a second sending subunit;

[0062] The first sending subunit is configured to send a command that the volume manager is in a closed state to the CPLD;

[006...

Embodiment 3

[0065] Embodiment 3 provides a computer-readable storage medium, where the computer-readable storage medium stores a computer program that executes the above method when executed by a processor.

[0066] Finally, it should be noted that those of ordinary skill in the art can understand that all or part of the process in the method of the above-mentioned embodiments can be implemented by instructing the relevant hardware through a computer program, and the program of the method of monitoring software can be stored in a computer readable In the storage medium, when the program is executed, it may include the processes of the foregoing method embodiments. Wherein, the storage medium of the program may be a magnetic disk, an optical disk, a read only memory (ROM) or a random access memory (RAM) or the like. The above computer program embodiments can achieve the same or similar effects as any of the foregoing method embodiments corresponding thereto.

[0067] In addition, the meth...

Abstract

The invention discloses a hard disk backplane lighting method, system and storage medium in the POST stage, comprising the following steps: the first step is to set a control right closing strategy and a control right recovery strategy, and turn off the hard disk backboard of the CPLD through the control right closing strategy. Board lighting control right; second step, judge whether the driver of the volume manager is loaded; third step, if the loading is complete, execute the control right recovery strategy; the control right recovery strategy is: obtain the volume manager state, and according to the state of the volume manager, determine whether to send the command that the volume manager is in the open state to the CPLD; restore the hard disk backplane lighting control right of the CPLD through the control right recovery strategy, The CPLD executes the lighting operation of the hard disk backplane; through the above method, the present invention avoids the problem of abnormal lighting caused by the CPLD being able to control the lighting of the hard disk backplane when the volume manager driver is not loaded, and realizes the safe and standardized lighting operation.

Description

technical field [0001] The invention relates to the technical field of volume managers, in particular to a method, system and storage medium for lighting a hard disk backplane in the POST stage. Background technique [0002] The existing hard disk backplane lighting method in the POST stage is as follows. In the PEI stage, the BIOS sets the VMD to be on or off, and then enters the DXE stage to load the VMD driver. Therefore, there is an idle time after setting the VMD on and before the VMD driver is loaded. ; During this idle time, the VMD driver has not been loaded, and the BIOS has sent the command that the VMD is on to the BMC, and sent it to the CPLD through the BMC, giving the control of the back panel light to the CPLD; the prior art The disadvantage is that during this idle time, the CPLD has the problem of controlling the backplane of the hard disk to perform abnormal lighting. SUMMARY OF THE INVENTION [0003] The main technical problem solved by the present inve...
