Obviously, the described The embodiments are only some of the embodiments of the present invention, not all of them.

CRC: cyclic redundancy check; stand-alone machine: universal server (only the head); composite model: universal server (head) + BOX (tail)

HD: hard disk; CM board: management board; BP1: hard disk backplane 1

Figure 1 is a schematic flow chart of a method according to an embodiment of the present invention. Among them, the execution subject in Figure 1 can be a positioning system for CRC error information of a composite machine.

As shown in Figure 1, the method includes:

Step 110: Analyze the connection topology of the main control board, hard disk backplane and cables of the composite model;

Step 120: Parse the error message from the cyclic redundancy check result of the composite model and obtain the associated serial number and port ID of the error message;

Step 130, parse the hard disk backplane number based on the associated serial number;

Step 140: Locate the component to which the error message belongs from the connection topology according to the hard disk backplane number and the port ID.

In order to facilitate the understanding of the present invention, the following is based on the principle of the method for locating the CRC error information of the composite model of the present invention, combined with the process of locating the CRC error information of the composite model in the embodiment, and the CRC error information of the composite model provided by the present invention is described below. Positioning methods are described further.

Specifically, the method for locating the CRC error information of the composite model includes:

S1. Analyze the connection topology of the main control board, hard disk backplane and cables of the composite model.

For example, the connection relationship between the CM board, four hard disk backplanes and cables is as follows:

CM_PHY0-7,28-35 are connected to 4 SAS cables;

CM_PHY12-15 is connected to BP4_PHY8-11;

CM_PHY16-19 is connected to BP3_PHY8-11;

CM_PHY20-23 is connected to BP2_PHY8-11;

CM-PHY24-27 is connected to BP1_PHY8-11;

Hard drive backplane 1: BP1_PHY0-7, 12-27, 32-35 are connected to BP1 28 HDs in sequence;

Hard drive backplane 2: BP2_PHY0-7, 12-27, 32-35 are connected to BP2 28 HDs in sequence;

Hard drive backplane 3: BP3_PHY0-7, 12-27, 32-35 are connected to BP3 28 HDs in sequence;

Hard drive backplane 4: BP4_PHY0-7,12-27,32-35==BP4 24 HDs are connected in sequence.

S2. Parse the error information from the cyclic redundancy check result of the composite model, and obtain the associated serial number and port ID of the error information.

Extract the bit error information before and after the hard drive is pressurized in the cyclic redundancy check result. If the error information before and after the hard drive is pressurized is inconsistent, it is determined to be an error message, and the associated serial number and port ID to which the error message belongs is parsed.

S3. Parse the hard disk backplane number according to the associated serial number.

Use the tool scrtnycli (this tool is used to perform CRC tests) to capture the BOX Expander serial number. For example, the SAS address of Expander serial number 4 is 56c92bf-0-03e5-b17f. The SAS address removes the separator - minus 1 to 56c92bf003e5b17d. You can use lsscsi-sgt The device corresponding to the SAS address is sg30, and the backplane can be found to be BP1 through the device name, that is, Expander3/6=CM, Expander4=BP1, Expander5=BP2, Expander7=BP3, Expander8=BP4.

S4. Locate the component to which the error message belongs from the connection topology according to the hard disk backplane number and the port ID.

Determine the faulty link from the connection topology based on the hard disk backplane number and port ID, and determine the faulty component based on the associated components of the faulty link in the connection topology.

For example, when using the tool scrtnycli to capture Expander serial numbers 3 to 8, the error information of each interface of the BOX is recorded as phy31.txt, phy41.txt to phy81.txt, and then perform a hard disk stress test. After the stress test is completed, capture again The error information of each interface of the BOX is recorded as phy32.txt, phy42.txt to phy82.txt. Compare phy41.txt and phy42.txt to see if they are completely consistent. If there are different lines, a CRC error will be reported. For example, if the lines of PHYID0 in Expander4 are inconsistent, it means there is a problem with the first hard disk on hard disk backplane 1, such as PHYID6 in Expander3. The rows are inconsistent. It just means that there is a problem with the four SAS cables connecting the CM board to the HOST.
