Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, fig. 1 is a flowchart of a CPLD diagnosis method according to an embodiment of the present application.
The CPLD diagnosis method provided by the embodiment of the application is applied to the target server and can comprise the following steps:
step S101: judging whether the CPLD of the target server is in an upgrading state or not; if the CPLD is in the upgrade state, step S102 is performed.
Step S102: before the CPLD transmits the target reset signal, diagnostic data of the CPLD is transmitted to a diagnostic server; the target reset signal comprises a reset signal which is sent to reset the main board after the CPLD is upgraded.
In practical application, considering that the CPLD sends a target reset signal for resetting the mainboard after upgrading is completed, the target reset signal can enable the mainboard to be powered on and powered off, correspondingly, a diagnosis tool for diagnosing the CPLD on the mainboard is powered off abnormally and cannot transmit diagnosis data to a diagnosis server, so that the CPLD is required to be diagnosed again later, the diagnosis efficiency is lower, in order to solve the problem, after the CPLD is judged to be in an upgrading state, the diagnosis data is directly sent to the diagnosis server before the CPLD sends the target reset signal, so that the diagnosis server can store diagnosis information of the CPLD, and then after the CPLD is upgraded, diagnosis can be continued on the basis of the diagnosis data, the CPLD is not required to be diagnosed by a heavy head, and the diagnosis efficiency is high.
It should be noted that the type of the diagnostic data may be determined according to actual needs, for example, the diagnostic data may include a diagnostic test result, a diagnostic test log, and the like, which are not specifically limited herein.
The CPLD diagnosis method is applied to the target server and used for judging whether the CPLD of the target server is in an upgrading state or not; if the CPLD is in an upgrade state, transmitting diagnostic data of the CPLD to a diagnostic server before the CPLD transmits a target reset signal; the target reset signal comprises a reset signal sent after the CPLD is upgraded. In the method, the target server transmits the diagnosis data of the CPLD to the diagnosis server when the CPLD is in an upgrading state and before the CPLD transmits the target reset signal, so that the condition that the diagnosis data is lost due to system reset caused by the target reset signal is avoided, the CPLD is prevented from being diagnosed again, and the diagnosis efficiency of the CPLD can be improved.
In the CPLD diagnosis method provided by the embodiment of the application, the fact that the upgrading tool for upgrading the CPLD prints the corresponding upgrading log in the process of upgrading the CPLD is considered, and if the upgrading log is printed successfully, the upgrading of the CPLD is indicated, so that whether the CPLD is upgraded can be judged by means of the log printing progress of the upgrading tool, and whether the CPLD is transmitted or not is determined, namely, the diagnosis data of the CPLD is transmitted to the diagnosis server by the target server before the CPLD transmits the target reset signal, and the log printing progress of the upgrading tool for upgrading the CPLD can be obtained; judging whether the log printing progress reaches a preset progress or not; if yes, transmitting the diagnosis data to a diagnosis server.
In practical applications, since the transmission of the diagnostic data requires time, which is affected by the data amount of the diagnostic data, the preset progress may be determined based on the data amount of the diagnostic data before judging whether the log printing progress reaches the preset progress. Specifically, the time period for transmitting the diagnostic data can be estimated; and determining the printing progress before the time length of the log printing completion time as a preset progress.
In practical application, considering that a certain delay exists between the completion of CPLD upgrading and the transmission of a target reset signal, the delay can be used for transmitting diagnostic data, so that in a specific application scene, the preset progress can comprise the log printing completion progress; correspondingly, in the process of acquiring the log printing progress of the upgrading tool for upgrading the CPLD and judging whether the log printing progress reaches the preset progress, whether the log printing operation of the upgrading tool is finished or not can be scanned in real time based on a heartbeat mechanism; if the log printing operation of the upgrading tool is completed, determining that the log printing progress reaches the preset progress. It should be noted that, by means of the heartbeat mechanism, whether the log printing operation of the upgrade tool is completed can be flexibly, accurately and conveniently determined.
In the CPLD diagnosis method provided by the embodiment of the present application, in the process of transmitting the diagnosis data of the CPLD to the diagnosis server, if the diagnosis data is too large, the target server may not be able to transmit the diagnosis data and the motherboard is reset, so that the diagnosis data transmission is failed, in order to avoid such a situation, it is ensured that the diagnosis server can acquire the complete diagnosis data, and it may be determined whether the diagnosis data transmission is completed; if the diagnosis data is not transmitted, judging whether the CPLD sends out a target reset signal; if the CPLD sends out the target reset signal, the target reset signal is intercepted, and the target reset signal is released after the diagnosis data transmission is completed.
