Referring to fig. 2 in the prior art, a CPU is connected to an SAS controller via PCIE, and the SAS controller performs protocol conversion between PCIE and SAS/SATA to access and control a hard disk. Expander is an expansion of SAS PHY (physical link) of the SAS controller, and realizes that the SAS controller can support more hard disks under the condition of limited SAS PHY. And the SAS PHY corresponding to the Expander is connected with the hard disk, and OOB, rate negotiation, index and other processes are carried out on the hard disk through the SAS/SATA protocol to acquire information of the hard disk. After the address space of the PCIE is allocated by the BIOS, the SAS controller already obtains information of the hard disk from the Expander through the Discovery process, and in this process, the SAS card can obtain information of the model, rate, capacity, and the like of the hard disk.
The BMC interacts with the SAS controller through I2C, and information acquired by the BMC on the hard disk is consistent with information acquired by the SAS controller but not consistent with an actual physical slot position. Since the SAS controller identifies that the hard disk is random in the Discovery process, the hard disk which is preferentially discovered is allocated to Slot1, and then allocated to slots 2,3,4,5, and the like in sequence. The SAS PHY of the Expander corresponds to the actual physical slot position of the hard disk, but different PHYs of the Expander can be used in the insertion method of the hard disk with different configurations, and the positions of the PHYs of the Expander are not consistent with the actual physical slot position due to the same different wiring modes of the Expander.
On a storage server with flexible configuration, the actual physical slot position display of a hard disk always causes confusion to manufacturers and operators, the confusion is solved by lighting, setting a fixed disk symbol under an OS (operating system) and the like, but aiming at a completely damaged hard disk, the disk symbol cannot be distributed under the OS, the mode of the fixed disk symbol is adopted, the same configuration is adopted, different machines have difference due to the difference of identifying the hard disk, and the uniqueness is not realized under the condition that a plurality of machines operate; the lighting mode is limited by the acquisition of the drive letter and the operation of manual or distributed software.
The following further illustrates embodiments of the invention according to the example shown in fig. 3. Firstly, an SAS PHY corresponding to the Expander is connected with the hard disk, and OOB, rate negotiation, index and other processes are carried out on the SAS/SATA protocol and the hard disk to obtain information of the hard disk. At this time, the unique identifier of the hard disk, such as SN, SAS address or UUID, needs to be obtained.
After the Expander acquires the unique information of the hard disk (in this embodiment, an SAS address is taken as an example), the Expander confirms the hard disk information on the corresponding SAS PHY, establishes a table of the SAS PHY and the SAS address of the hard disk, and confirms the corresponding relationship.
The expansion aiming at the Expander is mainly hard disk backboard or cable expansion, after the configuration of the storage server is selected, the distribution topology of the hard disk can be confirmed, and then a corresponding relation table of the Expander PHY and the hard disk physical position can be established. However, at this time, the information of the hard disk, the information of the CPLD, and the like are not obtained yet, so that the correspondence relationship is not correct after the Expander initialization is completed.
And then, acquiring information of different backplanes through the CPLD, confirming the current configuration by the in-place information of the hard disk, and communicating with the Expander through I2C. Specifically, the CPLD detects the state of the hard disk backboard through the GPIO, confirms the configuration of the storage server, and corresponds to the configuration file in the Expander; and the CPLD detects the in-place information of the hard disk through the GPIO, confirms that the actual physical slot is in place, informs the Expander, and processes the situation that the SAS PHY does not acquire the hard disk information to distinguish the situation that the hard disk fails or is not inserted into the hard disk.
After the Expander acquires the information of the CPLD, the corresponding physical configuration of the storage server is decoded, the corresponding configuration file is reloaded (the part corresponding to the physical position of the SAS PHY and the hard disk is loaded), the acquired hard disk information corresponds to the configuration file, the hard disk is distributed and processed aiming at the fault hard disk or not, and then the corresponding relation between the SAS PHY and the physical slot position is reconfirmed.
The BMC displays the actual physical slot position and the corresponding hard disk information on a BMC Web interface through interaction with the Expander.
As can be seen from the foregoing embodiments, in the method for determining a physical location of a hard disk provided in an embodiment of the present invention, a hard disk expander accesses all hard disks connected thereto based on a current physical link to obtain a unique identifier of the hard disk, and generates a first corresponding relationship between the physical link and the unique identifier; loading the configuration file by the hard disk expander to generate a second corresponding relation of the expected physical link and the physical position; the complex programmable logic device detects the backboard state and in-place signal of all hard disks and transmits the backboard state and in-place signal to the hard disk expander; enabling the hard disk extender to reload the configuration file based on the backboard state and the in-place signal so as to update the second corresponding relation into a third corresponding relation between the determined physical link and the physical position; the technical scheme that the baseboard management controller obtains the first corresponding relation and the third corresponding relation from the hard disk expander to determine and output the corresponding relation between the unique identifier and the physical position based on the first corresponding relation and the third corresponding relation can accurately determine the physical position of the hard disk, improve operation and maintenance efficiency and reduce operation and maintenance professional requirements.
