Embodiment 1

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

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

[0048] Specifically, in the PEI phase in the POST phase, the BIOS sends the command that the volume manager of each hard disk port is closed to the BMC; that is, the value of the register that makes the volume manager in the closed state is defined as the closed state value; 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 control right of the hard disk backplane light, and avoids the hard disk backplane...

Embodiment 2

[0057] This embodiment 2 provides a hard disk backplane lighting system at 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 loading of the driver of the volume manager is completed; after the loading of the driver of the volume manager is completed, the value of the register is obtained, and the volume manager is judged according to the value of the register status;

[0060] The control unit is used for controlling 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 clo...

Embodiment 3

[0065] Embodiment 3 provides a computer-readable storage medium, and the computer-readable storage medium stores a computer program for executing 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 processes in the methods of the above embodiments can be realized through computer programs to instruct relevant hardware to complete, and the program of the monitoring software method can be stored in a computer-readable In the storage medium, when the program is executed, it may include the processes of the embodiments of the above-mentioned methods. 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), and the like. The foregoing computer program embodiments can achieve the same or similar effects as any of the foregoing method embodiments corresponding thereto.

[0067] In addition,...

Abstract

The invention discloses a POST stage hard disk backboard lighting method and system and a storage medium, and the method comprises the following steps: 1, setting a control right closing strategy and a control right recovery strategy, and closing the hard disk backboard lighting control right of a CPLD through the control right closing strategy; 2, judging whether the drive of the volume manager is loaded or not; 3, if the loading is completed, executing the control right recovery strategy; the control right recovery strategy comprises the following steps: acquiring the state of the volume manager, and judging whether a command indicating that the volume manager is in an open state is sent to the CPLD or not according to the state of the volume manager; recovering the hard disk backboard lighting control right of the CPLD through the control right recovery strategy, wherein the CPLD executes a hard disk backboard lighting operation. By means of the mode, the problem of abnormal lighting caused by the fact that the CPLD can control lighting of the hard disk backboard when the volume manager drive is not loaded is avoided, and safe and standard lighting operation is achieved.

Description

technical field [0001] The present invention relates to the technical field of volume managers, in particular to a hard disk backboard lighting method, system and storage medium at the POST stage. Background technique [0002] The current method of lighting the hard disk backplane 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 to the on state and before the VMD driver is loaded. ; During this idle time, the VMD driver has not been loaded yet, and the BIOS has sent the command that the VMD is open to the BMC, and sent to the CPLD through the BMC, and handed over the control of the backplane light to the CPLD; The disadvantage is that during the idle time, the CPLD has the problem of controlling the hard disk backplane to perform abnormal lighting. Contents of the invention [0003] The technical problem mainly solved by the...
