And adding the device object of the target device into the on-board device expansion information to realize expansion of the device object in the on-board device expansion information, so that the on-board device expansion information contains the device objects of all devices in the target server.

According to the equipment position determining method provided by the embodiment of the invention, the target equipment which does not exist in the on-board equipment expansion information of the SMBIOS is determined from the equipment, and the equipment object of the target equipment is added into the on-board equipment expansion information, so that the expansion process of the equipment object in the on-board equipment expansion information is realized.

The following describes a technical solution provided by an embodiment of the present invention, taking a flowchart of a method for determining a device location provided by an embodiment of the present invention as an example fig. 3:

step 310, the function implementation scheme and result of the original on-board device extension information, i.e. Type41, in the original SMBIOS are reserved, so that the related information of the on-board device can be normally collected and reported to the SMBIOS function interface for interacting information with the operating system.

Step 320, based on step 310, the Type41 function is rewritten and extended, so that the function is further extended to all devices in the target server, that is, the device information defined in the Type41 of all devices is collected, and generated into individual Type41 functional entities, which are filled in the SMBIOS functional interface, and spliced at the back of the data implemented in step 310, where other splicing manners, such as putting in front, or interleaving, may be used according to the function needs.

In step 330, the LSPCI Function supporting module/driver under the linux operating system will read the Device silk-screen information of each Device from Type 41 and then implement it into the Device Name field of the LSPCI information of the Device, because the LSPCI Function will also collect Bus/Device/Function numbers of the devices, the set of data combinations of each Device is unique, and the set of data can be used to match each End Device, thereby obtaining the Device silk-screen information of each Device, so that the Function of displaying the Device silk-screen information in the Device's Device Name field in the LSPCI information is implemented.

And step 340, executing the LSPCI instruction in the operating system of the target server to acquire the device silk-screen information of each device.

In step 350, the Device Name implemented may be optional, may be all devices, or may be a certain type of Device or a combination of some types of devices, for example, one or more types of devices such as a hard disk, a network card, a Raid card, etc., and may be determined in combination with specific functional requirements.
