The embodiment of the application provides a control method and device of storage equipment, electronic equipment and a storage medium. The method provided by the embodiment of the invention can be applied to any required electronic equipment, for example, the electronic equipment can be electronic equipment such as a server and a terminal, and the method is not particularly limited herein, and is hereinafter simply referred to as electronic equipment for convenience in description.
According to an aspect of embodiments of the present application, a method embodiment of a method for controlling a storage device is provided. Fig. 1 is a flowchart of a control method of a storage device according to an embodiment of the present application, and as shown in fig. 1, the method includes:
step S11, a failure detection request is obtained, where the failure detection request is used to detect whether there is a failure between the current storage device and a target storage device, and the target storage device is a storage device having an association relationship with the current storage device.
The method provided by the embodiment of the application is applied to a processor deployed in a current storage device, wherein the processor is provided with a timing program, the timing program is used for periodically triggering a fault detection request, and the fault detection request is used for detecting whether a communication fault exists between the current storage device and a target storage device, for example: fiber link failure, etc. The target storage device is connected with the current storage device through an optical fiber link.
Step S12, in response to the failure detection request, performing an access operation on the target storage device to obtain an access result, and determining a first operating state corresponding to the optical fiber link deployed between the current storage device and the target storage device based on the access result.
In the embodiment of the present application, as shown in fig. 2, performing an access operation on a target storage device to obtain an access result includes the following steps a1-a 2:
step a1, an access request is sent to a target storage device over a fiber optic link.
In an embodiment of the application, in response to the failure detection request, the processor sends an access request to the target storage device through the optical fiber link for connecting the current storage device and the target storage device. It should be noted that the target storage device is also disposed with the same processor as the current storage device, and is used for receiving the access request.
Step A2, monitoring the transmission condition corresponding to the access request, and determining the access result based on the transmission condition.
In the embodiment of the application, after the processor sends the access request, whether the access request is sent successfully is monitored, so that the access result is determined. For example: and after receiving the access request, the target storage device feeds back confirmation information to the current storage device, and if the confirmation information is received, the target storage device determines that the sending condition is successful. And if the access request is not sent out, determining that the sending condition is sending failure. When the sending condition is sent, the access result is successful. When the sending condition is not sending, the access result is access failure.
In an embodiment of the present application, determining, based on the access result, a first operating state corresponding to a fiber link deployed between a current storage device and a target storage device includes: and when the access result is successful, determining that the first running state corresponding to the optical fiber link between the current storage device and the target storage device is a normal state. And when the access result is access failure, determining that a first operation state corresponding to the optical fiber link between the current storage device and the target storage device is a fault state.
In step S13, when the first operating state is the optical fiber link failure state, a first power state corresponding to the power source in the current storage device is detected.
In the embodiment of the application, detecting a first power state corresponding to a power supply in a current storage device comprises the following steps B1-B2:
and step B1, acquiring at least two power supply output conditions obtained by detecting the power supply of the current storage device by at least two sensors deployed in the current storage device.
In the embodiment of the application, when the first operating state is the optical fiber link failure state, whether the power supply in the current storage device can normally output is detected through at least two sensors deployed in the current storage device, so that the corresponding number of power supply output conditions are obtained.
And step B2, determining a first power state of the current storage device based on the power output conditions, wherein the first power state is a normal state when at least one power output condition is used for indicating that the power is normally output.
In the embodiment of the application, the processor receives the power output conditions fed back by the sensors, and when at least one power output condition is used for indicating that the power is normally output, the first power state is a normal state. Alternatively, when all of the power output conditions are used to indicate that the power output is abnormal, the first power state is an abnormal state.
As an example, the processor is connected with the sensor a and the sensor B respectively, controls the sensor a and the sensor B to detect the output condition of the power supply, receives the power supply output condition fed back by the sensor a and the sensor B respectively, and determines that the first power supply state is the normal state when at least one power supply output condition is used for indicating the normal output of the power supply.
In step S14, when the first power state is a failure state, a device switching operation is performed to cause the target storage device to serve in place of the current storage device.
In this embodiment, when the first power state is a failure state, it indicates that the current storage device is powered off at this time, and the processor cannot access the target storage device through the optical fiber link, and then the lease validity period is skipped, and device switching is performed immediately.
It should be noted that, in the prior art, frequent double-active failover caused by fiber network fluctuation can be avoided by introducing lease validity period, but the failover time is lengthened. If the position of the storage device A has power failure, the A cannot continue the service, and the double-active fault switching logic is continued after the lease expiration, so that the double-active fault switching time is prolonged by a lease validity period.
Therefore, only when the power supply of the current storage device is abnormal, it indicates that the abnormality of the optical fiber link is caused by power failure, rather than network fluctuation (conversely, if the power supply is in a normal state, it indicates that the abnormality of the current optical fiber link is caused by network fluctuation), so that the situation that the storage devices cannot be normally accessed due to network fluctuation can be quickly eliminated by detecting the power supply state, at this time, the processor does not verify whether the current storage device exceeds the lease effective time period any more, and directly performs device switching, thereby performing effective device switching operation, and simultaneously saving unnecessary device switching time compared with the prior art.
Therefore, the power supply state is determined by detecting the output condition of the power supply, and the reason that normal access cannot be performed between the storage devices can be quickly determined, so that double-active fault switching cannot be triggered when the network fluctuates, the device switching time during real fault is reduced, and the service efficiency of the storage devices is ensured.
In this embodiment of the present application, if the power is normal, then determining whether the current storage device exceeds the lease validity period, the specific method includes the following steps C1-C2:
and step C1, inquiring the valid time period corresponding to the current storage device when the first power supply state is the normal state.
And step C2, in case that the current time is determined not to belong to the valid time period, executing the device switching operation to make the target storage device replace the current storage device for service.
In an embodiment of the application, the method further comprises the following steps D1-D2:
and D1, monitoring the second operation state of the optical fiber link within the preset time under the condition that the current time is determined to belong to the valid time period.
And D2, controlling the current storage device to continue to be served when the second operation state is the normal state of the optical fiber link.
In the embodiment of the application, whether the lease of the storage device is over-term is judged according to the valid time period of the lease, and if the lease is over-term, the device switching operation is carried out. If the state of the optical fiber link returns to normal within the valid time period of the lease, the equipment switching operation is not carried out.
In this embodiment of the application, when the first power state is a normal state, the method further includes: generating a first communication signal based on the first power state; and broadcasting the first communication signal to the target storage device so that the target storage device executes the device switching operation based on the first communication signal under the condition that the power supply of the target storage device is failed.
In this embodiment of the application, when the first power state is a normal state, the method further includes: and under the condition of determining the first power state, generating an initial communication signal, and carrying the first power state in the initial communication signal to obtain a first communication signal. The processor broadcasts the first communication signal, so that the processor of the target storage device receives the first communication signal and stores the first communication signal. In the case where the target storage device has a power failure, it is possible to make sure that the current storage device is normal based on the first communication signal, and thus the target storage device can perform a device switching operation. Therefore, the service corresponding to the target storage device is guaranteed to be switched to the device in the survival state (namely the current storage device).
In this embodiment of the application, when the first power state is a normal state, the method further includes: monitoring a second communication signal broadcasted by the target storage equipment; and under the condition that the second communication signal is not monitored within the preset time, determining that the power supply of the target storage equipment has a fault, and executing equipment switching operation to enable the current storage equipment to replace the target storage equipment for service.
In this embodiment of the application, when the first power state is a normal state, the processor may further monitor a second communication signal broadcasted by the processor located on the target storage device, and if the processor does not monitor the second communication signal within a preset time, it is determined that the power of the target storage device has a fault, which results in that the processor of the target storage device cannot broadcast the communication signal, and at this time, the current storage device may automatically perform a device switching operation, so that it is ensured that a service corresponding to the target storage device is switched to the current storage device.
