Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Next, a fan redundancy testing method provided by the embodiment of the invention is described in detail. Fig. 1 is a flowchart of a fan redundancy testing method according to an embodiment of the present invention, where the method includes:
s101: and receiving a fan redundancy test instruction.
In the embodiment of the invention, in order to distinguish different fans, identification information which is uniquely corresponding to each fan is set for each fan. The identification information may be provided in the form of numbers, letters, or a combination of both.
The redundant test instructions are used to indicate a simulated fan failure. Fan identification information is carried in the redundant test instructions.
S102: and setting the target fan corresponding to the fan identification information as a failure mode.
To facilitate differentiation from other fans, the fan corresponding to the fan identification information in the redundant test instructions may be referred to as the target fan.
In practical applications, redundant fans are often provided to ensure the effectiveness of heat dissipation of the server. For example, in a normal state, 8 fans are arranged to meet the heat dissipation requirement of the server; in the redundancy mode, 10 fans may be provided, with any 8 fans in the normal operating mode and the remaining 2 fans in the redundancy mode. At this time, the maximum number of fan redundancies supported by the server is 2, that is, any 2 fans have a fault, and the fans in the redundancy mode can be called to replace the fault fans to work, so that normal heat dissipation of the server is ensured.
When the fan failure is simulated, the number of the target fans is required to be set to be less than or equal to the redundant number of the fans.
In the embodiment of the invention, the wind speed of the target fan corresponding to the fan identification information can be set to be zero, so that the effect of simulating the fan fault is achieved.
S103: and judging whether the rotating speed of the target fan meets the requirement of the fault mode and whether the rotating speeds of the residual fans meet the preset operation requirement.
When a fault fan occurs, the fan in the redundancy mode needs to be called to replace the fault fan to work, because the short-time switching of the fan is involved, and the rotating speed of the fan in the redundancy mode is zero, a certain time is needed for the rotating speed to reach the normal required rotating speed, and in order to ensure the heat dissipation effect of the server, the rotating speed of the fan in the running mode often reaches the full-speed state within the short time of replacement.
Taking the fan rotation speed at the time of the fault as an example, in a specific implementation, it may be determined whether the rotation speed of the target fan and the rotation speed of the fan in the redundant mode among the remaining fans are both zero, and whether the rotation speed of the fan in the operational mode among the remaining fans is full speed.
When the target fan speed and the fan in the redundant mode among the remaining fans are both zero, and the fan in the operational mode among the remaining fans is full speed, it indicates that the operational status of each fan is normal, and S104 may be executed.
When the rotation speed of the target fan does not satisfy the failure mode requirement or the rotation speeds of the remaining fans do not satisfy the preset operation requirement, S106 may be performed at this time.
It should be noted that, in order to ensure the heat dissipation effect of the server, the rotation speed of the fan in the operation mode tends to reach the full speed state within the short time of replacement. The fan consumes more power at full speed and generates more noise. Therefore, the full-speed state of the fans does not last too long, when the rotating speed of each fan in the operation mode reaches full speed, the heat dissipation of the server can be effectively ensured, and in order to reduce the power consumption of the system, the rotating speed of the fan in the operation mode can be restored to the normal rotating speed.
S104: and detecting whether the file for recording the running state of the fan records abnormal prompt information or not.
Under the normal state, when a fan has a fault, the abnormal prompt information of the fault fan is recorded in the file.
Therefore, after the target fan corresponding to the fan identification information is set to the failure mode, if the abnormality prompt information is recorded in the file, it indicates that the fans other than the target fan can normally operate in the failure mode, and at this time, S105 may be executed.
After the target fan corresponding to the fan identification information is set to the failure mode, if the abnormality prompt information is not recorded in the file, it indicates that there is an error in the information recorded in the file, and then S106 may be executed.
S105: and displaying prompt information of stable operation of the fan.
Due to the presence of a failed fan, there will be a corresponding exception prompt in the file. Therefore, when the rotating speed of the target fan meets the requirement of the fault mode and the rotating speeds of the remaining fans meet the preset operation requirement, if abnormal prompt information is recorded in the file, the system can realize the automatic test of the operation stability of the fans. In order to facilitate the user to know the test result, prompt information of stable operation of the fan can be displayed.
S106: generating log information and displaying prompt information of abnormal fan operation.
The log information records the operating state information of each fan.
When the rotating speed of the target fan does not meet the requirement of the fault mode or the rotating speeds of the remaining fans do not meet the preset operation requirement, or the file does not record abnormal prompt information, the problem exists when the system executes the automatic test of the operation stability of the fans, and the prompt information of the abnormal operation of the fans can be displayed at the moment, so that a user can be reminded to check the operation condition of each fan in time.
According to the technical scheme, the fan redundancy test instruction is received; the redundancy test instruction carries fan identification information; setting a target fan corresponding to the fan identification information to a failure mode; and the number of the target fans is less than or equal to the redundant number of the fans. And judging whether the rotating speed of the target fan meets the requirement of the fault mode and whether the rotating speeds of the residual fans meet the preset operation requirement. And when the rotating speeds of all the fans meet the requirements in the corresponding modes, detecting whether the file for recording the running state of the fans records abnormal prompt information or not. Under the normal state, when a fan has a fault, the abnormal prompt information of the fault fan is recorded in the file. Therefore, when the abnormal prompt information is recorded in the file, it indicates that the fans except the target fan can normally operate in the failure mode, and the prompt information that the fan operates stably can be displayed. And when the abnormal prompt information is not recorded in the file, generating log information and displaying the prompt information of the abnormal operation of the fan. The technical scheme can realize the automatic test of the running stability of the fan and can timely find the abnormal running condition of the fan.
In the embodiment of the present invention, the test time may be set for each test, and specifically, the test time may be carried in the fan redundancy test instruction.
The test time may be any integer time within a preset time, for example, an integer may be randomly selected as the test time within 1 to 15 minutes.
When the test time is set, after the target fan corresponding to the fan identification information is set to be in the fault mode, the prompt information of the end of the test can be displayed when the test time is reached.
The test completion prompt information is displayed, so that the user can be timely reminded of the test completion, the user can reset the test time and select the fault fan, and the next round of test can be performed.
After the target fan corresponding to the fan identification information is set to the failure mode, when an instruction to exit the redundancy test is received, all fans are restored to the initialization state mode.
Before the test, when the target fan belongs to the fan in the redundancy mode, the target fan can be adjusted to the redundancy mode when an instruction for quitting the redundancy test is received; before the test, when the target fan belongs to the fan in the running mode, the target fan can be adjusted to the running mode when an instruction for exiting the redundancy test is received.
Wherein, the fan speed in the redundancy mode can be set to zero; the fan speed may be set to a normal speed in the operating mode, wherein the normal speed may be set to half of a full fan speed value.
In the embodiment of the present invention, except that the fan is restored to the initialization state mode when the instruction to exit the redundancy test is received, an automatic exit mode may be adopted, and specifically, when the test time is reached, the fan is automatically restored to the initialization state mode.
After each test result, all fans are restored to the initialization state mode, so that the fans of the system can be guaranteed to be restored to respective corresponding normal running states, and the state of each fan cannot be influenced by the previous test in the next test.
In the embodiment of the present invention, after all the fans are restored to the initialization state mode, it can be determined whether the rotation speeds of all the fans meet the rotation speed requirements in the corresponding modes within the preset time.
The preset time may be set according to the time for recovering the rotation speed of the fan, and is not limited herein.
In a normal state, after all fans are restored to an initialization state mode, the rotating speed of the fans in a redundancy mode should be zero; the fan in the run mode should be at normal speed.
When the rotating speeds of all the fans do not meet the rotating speed requirements in the corresponding modes within the preset time, the existence of the fan with abnormal operation is indicated, corresponding log information can be generated for all the fans at the moment, and prompt information of the fan with abnormal operation is displayed, so that a user can be reminded of checking the fans in time.
When the rotating speeds of all the fans meet the rotating speed requirements in the corresponding modes within the preset time, selecting a new target fan from the remaining fans except the target fan, and executing the step of setting the new target fan to be in the failure mode; and ending the operation until no new target fan exists or the preset total test time is reached.
In the embodiment of the invention, the fan in the system can be tested for multiple times, and different fans can be selected as fault fans in each test. In a specific implementation, a total test time may be set, timing is started from the time of the first test, when the total test time is reached, it indicates that the redundancy test of the fan is completed, and at this time, the operation may be ended.
After the test is finished at every time, the running state of each fan is detected, the condition that the fan breaks down after the test is finished can be found in time, and the accuracy of stability detection of each fan is improved.
