[0041] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0042] It should be noted that, in the description of this application, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. The terms "first," "second," etc., in this application are used to distinguish similar objects, and are not used to describe a particular order or sequence.

[0043] For example, Figure 1 Schematic diagram of the fault location scenario in related technologies. Figure 1 As shown, the scenario includes a computing device 10 and an analyzer 30. In the computing device 10, a host controller 101 can be connected to multiple hard disks through an expander 102. For example, Figure 1 Three hard disks are shown, namely hard disk 103 , hard disk 104 and hard disk 105 .

[0044] In order to ensure the storage reliability of computing devices, real-time monitoring and fault location of links are required.

[0045] In the related art, it is necessary to disconnect a link (a link between a hard disk and an expander, or a link between an expander and a host controller) and connect the analyzer 30 to the link (such as a link between a hard disk and an expander) to locate the fault based on the monitored link signal.

[0046] However, in the related art, destroying the original link to access the analyzer will, on the one hand, change the original topology structure and signal transmission environment of the link, and on the other hand, only detect the link signal of one link, resulting in the method in the related art having a low accuracy rate in fault location.

[0047] Therefore, in response to the above technical problems in the relevant technology, it was found in the process of research that if a signal acquisition module (including multiple acquisition components (each acquisition component can acquire the link signal of the link)) with the ability to detect link signals and a signal processing module with the ability to process link signals are combined with an expander to form an expansion module, and then the acquisition component is set between the host controller and the expander, or between the hard disk and the expander, the expansion module can be equipped with the ability to acquire link signals of multiple links and analyze them without destroying the original topology structure and signal transmission environment of the link. Therefore, the present application proposes an expansion module, a fault location method, a terminal device, a medium and a product. Specifically, the expansion module includes an expander, a signal acquisition module and a signal processing module; the signal acquisition module includes multiple acquisition components; the expansion module belongs to a computing device; the signal processing module is connected to the expander and the signal acquisition module respectively; for any acquisition component in the signal acquisition module, the host controller in the computing device is connected to the expander through the acquisition component; or, the hard disk in the computing device is connected to the expander through the acquisition component.

[0048] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0075] For acquisition component 0, the host controller 201 is connected to port 0 of the expander 2022 through the acquisition component 0.

It should be noted that the link connecting the hard disk 1 to the port 5 of the expander 2022 through the acquisition component 5 can be a link for the signal acquisition module 2021 to collect link signals based on the acquisition component 5.

[0081] Regarding the acquisition component 6, the hard disk 1 is connected to the port 6 of the expander 2022 through the acquisition component 6. It should be noted that the link connecting the hard disk 2 to the port 6 of the expander 2022 through the acquisition component 6 can be a link for the signal acquisition module 2021 to collect link signals based on the acquisition component 6.

For any acquisition component in the signal acquisition module, the host controller in the computing device is connected to a port of the expander through the acquisition component; or, the hard disk in the computing device is connected to a port of the expander through the acquisition component. Based on the above structure, the signal acquisition module can use each acquisition component to independently acquire the signal of each link. That is to say, based on the above structure, the signal analysis module supports the independent acquisition and processing of the link signal of a single link, and also supports the parallel acquisition and processing of the link signal of multiple links, thereby improving the efficiency and accuracy of the acquisition and processing of the link signal, and thereby improving the efficiency and accuracy of fault location.

[0117] Figure 5 A schematic diagram of a fault location method provided in an embodiment of the present application Figure 1 , see Figure 5, the method specifically comprises the following steps:

[0118] S501: Obtain an acquisition start instruction through the extender in the extension module, and send the acquisition start instruction to the signal acquisition module in the extension module.

[0119] In this embodiment, the expansion module includes an expander, a signal acquisition module, and a signal processing module. The signal acquisition module includes multiple acquisition components. The expansion module belongs to the computing device. The signal processing module is connected to the expander and the signal acquisition module respectively. For any acquisition component in the signal acquisition module, the host controller in the computing device is connected to the expander through the acquisition component; alternatively, the hard disk in the computing device is connected to the expander through the acquisition component.

[0120] In one implementation, the expander includes multiple ports. For any acquisition component in the signal acquisition module, a host controller in the computing device is connected to a port of the expander via the acquisition component; or a hard disk in the computing device is connected to a port of the expander via the acquisition component.

[0121] The extension module can obtain the acquisition start instruction through the expander and send the acquisition start instruction to the signal acquisition module.

[0122] The following describes the process of the expansion module obtaining the acquisition start instruction through the expander.

[0123] In one implementation:

[0124] Each link consists of multiple protocol layers, including the physical layer, link layer, port layer, transport layer, and application layer.

[0125] It should be noted that the link is a link connecting a host controller to a port of an expander via a collection component, or a link is a link connecting a hard disk to a port of an expander via a collection component.

[0126] The expansion module can determine whether there is a protocol layer in a fault state among multiple protocol layers of multiple links through the expander.

[0127] The following describes a process in which the extender determines whether a protocol layer in a plurality of protocol layers of a plurality of links is in a fault state.

[0128] In one implementation:

[0129] For any protocol layer of any link, the expansion module can obtain the value of the status register corresponding to the protocol layer through the expander.

[0130] The value of the status register is a first value or a second value, the first value indicates that the state of the protocol layer is a fault state, and the second value indicates that the state of the protocol layer is a normal state.

[0131] The expansion module can determine that there is a protocol layer in a fault state among the multiple protocol layers of the multiple links when the expander determines that the value of the status register corresponding to at least one protocol layer among the multiple protocol layers of the multiple links is the first value.

[0132] The expansion module can determine through the expander that there is no protocol layer in a fault state among the multiple protocol layers of the multiple links when the value of the status register corresponding to each protocol layer in the multiple protocol layers of the multiple links is all the second value.

[0133] The expansion module can generate a collection start instruction through the expander in the case where a protocol layer in a fault state exists in multiple protocol layers of multiple links.

[0134] In one implementation:

[0135] The expansion module can obtain the acquisition start instruction sent by the processor through the host controller through the expander.

[0136] The following describes the process of the processor generating a collection start instruction.

[0137] In one implementation, the acquisition start instruction is generated by the processor when it detects that a protocol layer in a faulty state exists among multiple protocol layers of multiple links. In one implementation, the host controller may generate alarm indication information when it identifies that a protocol layer in a faulty state exists among multiple protocol layers of multiple links. Upon receiving the alarm indication information sent by the host controller, the processor determines that a protocol layer in a faulty state exists among multiple protocol layers of the multiple links. It should be noted that each link includes multiple protocol layers; the link is a first link or a second link.

[0138] In one implementation, the acquisition start instruction is generated by the processor when an input / output (IO) error is detected. For example, the acquisition start instruction may be generated by the processor when an IO error is detected on hard disk 0.

[0139] In one implementation:

[0140] When the extender is connected to the terminal device, the extension module can obtain the collection start instruction sent by the terminal device through the extender.

[0141] It should be noted that, in one implementation, the terminal device may obtain a user-input collection start request. It is understandable that the terminal device may obtain the user-input collection start request through the terminal device's human-computer interaction interface. The terminal device may generate a collection start instruction based on the collection start request. In one implementation, the collection start request may include an analysis method. In one implementation, the analysis method may include an identifier of the target port. In another implementation, the analysis method may also include an identifier of the target protocol layer. In another implementation, the analysis method may also include an identifier of a signal characteristic.

[0142] S502: Determine, by the signal acquisition module, at least one target acquisition component from a plurality of acquisition components according to an acquisition start instruction, and acquire link signals of at least one link based on the at least one target acquisition component.

[0143] In this embodiment, the extension module may determine at least one target collection component from a plurality of collection components according to a collection start instruction via the signal collection module.

[0144] The following describes in detail the process in which the extension module determines at least one target acquisition component from a plurality of acquisition components through the signal acquisition module according to the acquisition start instruction.

[0145] In one implementation:

[0146] The acquisition start instruction includes an identifier of at least one target port. In addition, in one implementation, the acquisition start instruction may include an identifier of a target protocol layer and / or an identifier of a signal characteristic.
