Interface) address, and establish the correspondence between the number of each connector and each SCSI address. Each connector on the SAS backplane 11 has a unique number. For example, the first connector 12 is numbered J1 and the second connector 13 is numbered J2. The SAS hard disk connected to each connector on the SAS backplane 11 is assigned a SCSI address in the EFI environment. For example, the SCSI address of the first SAS hard disk 14 is SCSI (0x1, 0x0), and the second SAS is hard. The SCSI address of the disk 15 is SCSI (0x2, 0x0). The SCSI address is unique and fixed and will not change because the connector is connected to a different SAS hard disk. The number of each connector corresponds to the SCSI address of the SAS hard disk to which the connector is connected. For example, J1 corresponds to SCSI (0x1, 0x0), and J2 corresponds to SCSI (0x2, 0x0).

The document creation module 101 is configured to create a document, the number of each connector on the SAS backplane 11, the SCSI address corresponding to each connector, and the number of each connector and each SCSI bit. The correspondence of the addresses is stored in the document. The document can be an INI document.

The test module 102 is configured to determine whether to start testing the SAS hard disk connected to the connector on the SAS backplane 11 and test the SAS when testing the SAS hard disk connected to the connector on the SAS backplane 11 Whether the connector on the backplane 11 is in normal communication with the connected SAS hard disk. First, the test module 102 obtains a list of SCSI addresses of the SAS hard disks to which the connector on the SAS backplane 11 is currently connected. The test module 102 then compares the SCSI address in the obtained SCSI address list with the SCSI address stored in the document. If the SCSI address in the obtained SCSI address list is the same as the SCSI address stored in the document, it is determined that the connector on the SAS backplane 11 and the SAS hard disk to be tested are in normal communication; if the obtained SCSI bit is obtained If the SCSI address in the address list is different from the SCSI address stored in the document, it is determined that the connector on the SAS backplane 11 and one or more SAS hard disks to be tested cannot communicate normally, for example: SAS backplane The connector on 11 has poor contact with one or more SAS hard disks that need to be tested.

The prompting module 103 is configured to prompt the user to fail the test when the connector on the SAS backplane 11 fails to communicate with the connected SAS hard disk. The processing module 104 is configured to obtain a SCSI address corresponding to the SAS hard disk that cannot communicate with the connector on the SAS backplane 11 , and read the number of the connector corresponding to the SCSI address from the document according to the SCSI address, The SAS hard disk to which the connector corresponding to the connector number is read is the SAS hard disk that failed the test, and the number of the connector to which the failed SAS hard disk is connected is displayed on the display device 2 to For users to check. The SAS hard disk that cannot communicate normally with the connector on the SAS backplane 11 includes: a SAS hard disk corresponding to a SCSI address that exists in the file but does not exist in the SCSI address list.

The test module 102 is configured to perform a functional test on the SAS hard disk connected to the connector on the SAS backplane 11 when the connector on the SAS backplane 11 is in normal communication with the connected SAS hard disk, and determine whether the test is performed. success. In this embodiment, the functional test of the SAS hard disk includes testing the partition function of the SAS hard disk, the function of writing data, and the function of reading data. When the partition function of the SAS hard disk, the function of writing data, and the function of reading data are normal, it is judged that the function test of the SAS hard disk is successful; when the partition function of the SAS hard disk, the function of writing data, and reading data When all or part of the function is abnormal, it is judged that the function test of the SAS hard disk fails.

The prompt module 103 is further configured to prompt the user to test successfully when the function test of the SAS hard disk connected to the connector on the SAS backplane 11 is successful.

The processing module 104 is configured to obtain a SCSI address corresponding to the failed SAS hard disk when the function test of the SAS hard disk connected to the connector on the SAS backplane 11 is unsuccessful, according to the SCSI address The document reads the number of the connector corresponding to the SCSI address, the SAS hard disk to which the connector corresponding to the read connector number is connected, that is, the SAS hard disk that failed the test, and the SAS hard disk that failed the test. The number of the connected connector is displayed on the display device 2 for viewing by the user. For example, the obtained SCSI address corresponding to the failed SAS hard disk is SCSI (0x2, 0x0), and J2 corresponds to SCSI (0x2, 0x0) in the document, so the processing module 104 reads the connector from the document. No. J2, J2 is displayed on the display device 2.

Referring to FIG. 3, it is a flowchart of a preferred embodiment of a SAS hard disk test method in the EFI environment of the present invention. In step S10, the parameter acquisition module 100 acquires the number of each connector on the backplane 11 of the SAS (serial attached SCSI) interface, and the SCSI (small computer system interface) of each connector. System interface) address, and establish the correspondence between the number of each connector and each SCSI address.

Step S11, the document creation module 101 creates a document, the number of each connector on the SAS backplane 11, the SCSI address corresponding to each connector, and the number of each connector and each SCSI. The correspondence of the addresses is stored in the document.

In step S12, the test module 102 determines whether to start testing the SAS hard disk connected to the connector on the SAS backplane 11.

In step S13, when testing of the SAS hard disk connected to the connector on the SAS backplane 11 is started, the test module 102 tests whether the connector on the SAS backplane 11 is in normal communication with the connected SAS hard disk. First, the test module 102 obtains a list of SCSI addresses of the SAS hard disks to which the connector on the SAS backplane 11 is currently connected. The test module 102 then compares the SCSI address in the obtained SCSI address list with the SCSI address stored in the document. If the SCSI address in the obtained SCSI address list is the same as the SCSI address stored in the document, it is determined that the connector on the SAS backplane 11 and the SAS hard disk to be tested are in normal communication; if the obtained SCSI bit is obtained If the SCSI address in the address list is different from the SCSI address stored in the document, it is determined that the connector on the SAS backplane 11 and one or more SAS hard disks to be tested cannot communicate normally, for example: SAS backplane The connector on 11 has poor contact with one or more SAS hard disks that need to be tested.

When the connector on the SAS backplane 11 is not in normal communication with the connected SAS hard disk, the prompting module 103 prompts the user to fail the test, and then proceeds to step S18, and the processing module 104 acquires the back of the SAS. The SCSI address corresponding to the SAS hard disk that the connector on the board 11 normally communicates reads, according to the SCSI address, the number of the connector corresponding to the SCSI address is read from the document, and the connector number corresponding to the read connector number is The connected SAS hard disk is the SAS hard disk that failed the test. The SAS hard disk that cannot communicate normally with the connector on the SAS backplane 11 includes: a SAS hard disk corresponding to a SCSI address that exists in the file but does not exist in the SCSI address list. In step S19, the processing module 104 displays the number of the connector connected to the failed SAS hard disk on the display device 2 for the user to view.

When the connector on the test SAS backplane 11 is in normal communication with the connected SAS hard disk, in step S14, the test module 102 sequentially performs a functional test on the SAS hard disk connected to the connector on the SAS backplane 11. In step S15, the test module 102 determines whether the functional test of the SAS hard disk is successful. In this embodiment, the functional test of the SAS hard disk includes testing the partition function of the SAS hard disk, the function of writing data, and the function of reading data. When the partition function of the SAS hard disk, the function of writing data, and the function of reading data are normal, it is judged that the function test of the SAS hard disk is successful; when the partition function of the SAS hard disk, the function of writing data, and reading data When all or part of the function is abnormal, it is judged that the function test of the SAS hard disk fails. In step S17, when the function test of the SAS hard disk connected to the connector on the SAS backplane 11 is successful, the prompting module 103 prompts the user to successfully test and ends the process. In step S18, when the function test of the SAS hard disk connected to the connector on the SAS backplane 11 is unsuccessful, the prompting module 103 prompts the user to fail the test. The processing module 104 obtains the SCSI address corresponding to the failed SAS hard disk, and reads the number of the connector corresponding to the SCSI address from the document according to the SCSI address, and the connector corresponding to the read connector number is connected. The SAS hard drive is the SAS hard drive that failed the test. In step S19, the processing module 104 displays the number of the connector to which the SAS hard disk that failed the test is displayed on the display device 2 for the user to consult.
