Detailed Description
The core of the invention is to provide a testing method, a device, a system and a readable storage medium for BBU independent power supply, which effectively ensure that the BBU normally supplies power to the data storage equipment and improve the reliability and the safety of the BBU supplying power to the data storage equipment.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a process of a testing method for BBU independent power supply provided by the present invention, the method includes:
s10: detecting a power failure of the data storage device;
s11: judging whether the rectifying module outputs a power-down signal in a first period after the data storage device is powered down, if so, entering S12, and if not, entering S15;
s12: judging whether the controller outputs an enable signal in a second period after receiving the power-down signal, if so, entering S13, otherwise, entering S15;
s13: judging whether the BBU immediately supplies power to the data storage device after receiving the enabling signal and outputting a backup preparation signal to the data storage device in a third period so that the data storage device can perform data backup, if so, entering S14, otherwise, entering S15;
s14: judging that the BBU independently supplies power normally;
s15: and judging that the fault exists in the BBU independent power supply.
Specifically, the main idea of the present application is to determine whether the BBU independent power supply is normal through actions and time sequences performed by each device in a power preparation stage when the data storage module is powered down and the BBU independently supplies power. Based on this, in order to clearly understand the details of power supply when the BBU is independently powered, the present application determines whether the BBU is independently powered normally through a power signal of the data storage Device (to detect whether the output storage Device is powered down), a power down signal sent by the rectifier module, an enable signal sent by the controller (which may be a Complex Programmable Logic Device (CPLD), or other controllers, and is determined according to actual conditions), and a backup preparation signal sent by the BBU.
After the data storage device is powered down (the commercial power stops supplying power due to some reasons such as a fault or other reasons), it is determined whether the rectifier module under the action of the remaining power outputs a power down signal to the controller in a first period (for example, which may be, but is not limited to, 4ms) (which may be determined by whether a level signal of a corresponding pin of the controller changes, for example, when the data storage device is not powered down, the corresponding pin of the controller is at a low level, and when the data storage device is powered down, the corresponding pin of the controller is at a high level), if so, it is determined that the rectifier module is correct, it is then determined whether the controller under the action of the remaining power outputs an enable signal to the controller in a second period (for example, which may be, but is not limited to, to 10ms) after receiving the power down signal (which may be determined by a level signal of a corresponding pin of the BBU, if the BBU, the corresponding pin is low level, when the BBU receives the enabling signal, the corresponding pin is high level), if yes, the controller is indicated to have no problem, then whether the BBU immediately supplies power to the data storage device after receiving the enabling signal is judged, at this time, the BBU enters a backup preparation stage (the time is a third period, the third period can be but is not limited to 5s), if the BBU supplies power to the data storage device, the BBU also outputs a backup preparation signal to the data storage device in the backup preparation stage, the BBU independently supplies power normally, otherwise, the BBU independently supplies power normally, if not, any judgment is not satisfied, the BBU independently supplies power to normally, and which link has a problem when the BBU independently supplies power can be accurately judged through each judgment process, namely, the condition of the BBU independently supplies power can be completely checked through the signals.
In conclusion, the action characteristics and the corresponding time sequence of each module in the power supply preparation stage are correspondingly tested when the BBU is independently powered, so that the test of the BBU independent power supply in the power supply preparation stage is realized, the normal power supply of the BBU to the data storage device is effectively ensured, and the power supply reliability and the safety of the BBU to the data storage device are improved.
On the basis of the above-described embodiment:
as a preferred embodiment, the step S13, after supplying power to the data storage device, before outputting the backup preparation signal to the data storage device, further includes:
judging whether the BBU executes the following operations, if so, entering S14, otherwise, entering S15, wherein the following operations include:
when the BBU receives the enabling signal all the time, executing the subsequent steps;
when the BBU does not receive the enabling signal all the time, the power supply for the data storage device is stopped, and a backup preparation signal is not output to the data storage device.
Specifically, in the above embodiment, after receiving the enable signal, the BBU enters a backup preparation stage, and a situation that the commercial power is restored may occur before sending the backup preparation signal to the data storage device, that is, the commercial power restarts to supply power to the data storage device through the rectifier module, under such a situation, the BBU is not required to send the backup preparation signal to the data storage device again (data backup is required only when the data storage device is powered off, and backup is not required when the commercial power is normally supplied to the data storage device); when the BBU does not receive the enabling signal all the time (indicating that the commercial power starts to recover the power supply to the data storage device), whether to stop supplying power to the data storage device and not output a backup preparation signal to the data storage device is judged, if so, the BBU independently supplies power normally, otherwise, the BBU independently supplies power and has a fault. By the method, data can be effectively backed up when the mains supply does not supply power to the data storage equipment, data loss is prevented, the data storage equipment is not controlled to start data backup when the mains supply starts to supply power to the data storage equipment, and occupation of storage space is reduced. If the BBU correctly executes the corresponding steps according to the logic, the BBU independently supplies power normally, otherwise, the BBU independently supplies power with failure.
As a preferred embodiment, after outputting the backup preparation signal to the data storage device in step S13, the method further includes:
judging whether the BBU executes the following operations, if so, entering S14, otherwise, entering S15, wherein the following operations include:
when the BBU receives the enabling signal all the time, the BBU continues to output a backup preparation signal to the data storage device;
and when the BBU does not receive the enabling signal all the time, stopping supplying power to the data storage equipment and outputting the backup preparation signal to the data storage equipment.
Specifically, there is also a case where, after the BBU supplies power to the data storage device and has sent the backup preparation signal to the data storage device, in order to ensure that valid backup data can be performed when the commercial power does not supply power to the data storage device, and prevent loss of data, the data storage device is not controlled to start data backup when the commercial power starts supplying power to the data storage device, so as to reduce occupation of a storage space, it is necessary to determine whether the BBU continues to output the backup preparation signal to the data storage device when the BBU always receives the enable signal; and if the BBU correctly executes the corresponding steps according to the logic, the BBU independently supplies power normally, otherwise, the BBU independently supplies power with a fault.
As a preferred embodiment, in step S12, after receiving the power down signal, the controller further includes:
and judging whether the controller controls the alarm module to give an alarm in the fourth period, if so, entering S14, and otherwise, entering S15.
Specifically, in order to timely notify the relevant personnel when the data storage device is powered down, it is further required to determine whether the controller controls the alarm module to send an alarm in a fourth period (which may be, but not limited to, 1s), if so, it is indicated that the controller can timely notify the relevant personnel so that the relevant personnel can perform corresponding remedial measures, otherwise, it is indicated that the controller cannot timely notify the relevant personnel, and there may be a situation that data is lost and the relevant personnel do not know, if the controller can correctly execute corresponding steps according to the above logic, it is indicated that the BBU independently supplies power normally, and otherwise, it is indicated that the BBU independently supplies power and has a fault.
As a preferred embodiment, when the data storage device is not powered down, the method further comprises:
and controlling the data storage device to execute a script for powering down the data storage device for a fifth period.
As a preferred embodiment, the fifth period is 1 s.
Specifically, in order to test the BBU independent power supply, the test is usually not performed until the mains supply is actually powered off, but the mains supply is simulated to stop supplying power to the data storage device by turning off the switch between the mains supply and the rectifier module, where it is assumed that the power failure duration is the fifth period, in order to achieve the above purpose, in the prior art, the switch is usually manually turned off, but the fifth period is usually shorter, for example, but not limited to 1s, and the time is difficult to grasp manually, so that on one hand, the burden of a tester is increased, the test process is complicated, on the other hand, the simulation time is difficult to grasp, and the test accuracy is reduced.
In order to solve the problem, the method also comprises the step of setting a script, and controlling the data storage device to execute the script when the data storage device is not powered down so as to power down the data storage device for a fifth period. Because the fifth cycle is generally very short, under normal circumstances, the BBU is still in the backup preparation stage, and has not yet sent a backup preparation signal to the data storage device, and because the BBU does not receive the enable signal all the time, the BBU will stop supplying power to the data storage device and not output the backup preparation signal to the data storage device. Through this kind of mode, can accurately grasp simulation time, alleviateed tester's burden, improved the measuring accuracy.
In order to effectively verify the compatibility between the BBU independent power supply and the mains supply, the data storage device can be controlled to execute the script for multiple times, so that the data storage device is in a state that: and the three states of the power supply stop of the BBU are circulated to verify the compatibility between the BBU independent power supply and the commercial power.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a test system with an independent BBU power supply provided in the present invention, the test system includes:
the power failure signal judgment module 1 is used for judging whether the rectification module outputs a power failure signal in a first period after the data storage device is powered down is detected, if so, the enabling signal judgment module 2 is triggered, and otherwise, the fault judgment module 5 is triggered;
