The application discloses a storage device control method, device, electronic device and storage medium. Including: obtaining a fault detection request, the target storage device is a storage device that has an association relationship with the current storage device; in response to the fault detection request, performing an access operation to the target storage device, obtaining the access result, and determining the deployment in the current storage device based on the access result The first operating state corresponding to the optical fiber link between the device and the target storage device; in the case that the first operating state is an optical fiber link failure state, detect the first power state corresponding to the power supply in the current storage device; When the state is a failure state, perform a device switching operation. By detecting the power status of storage devices, this application can quickly determine the reason why storage devices cannot be accessed normally, so as to ensure that device switching will not be triggered when the network fluctuates, reducing the time for switching devices when there is a real failure, and at the same time ensuring that storage devices service efficiency.
Description
technical field [0001] The present application relates to the field of device control, and in particular, to a control method, device, electronic device and storage medium for a storage device. Background technique [0002] Active-active is a data disaster recovery solution with dual centers in the same city. The two storage devices are connected by optical fibers in the same city, and the two storage devices can undertake services at the same time. After receiving the service I / O, the data is copied to the opposite storage device through the background copy. In this way, data backup and protection can be performed, and storage performance can be fully utilized to achieve business load balance. Active-active is a very efficient and reliable data protection solution. One of the requirements is that when one of the storage devices A fails, the other storage device B can take over the storage device A to continue the business, ensuring that the business will not be interrupted...
