Abstract

The invention discloses a control method and device of storage equipment, electronic equipment and a storage medium. Comprising the steps that a fault detection request is obtained, and a target storage device is a storage device having an association relationship with a current storage device; in response to the fault detection request, executing an access operation on a target storage device to obtain an access result, and determining a first running state corresponding to an optical fiber link deployed between the current storage device and the target storage device based on the access result; when the first operation state is an optical fiber link fault state, detecting a first power supply state corresponding to a power supply in the current storage device; and under the condition that the first power supply state is the fault state, executing equipment switching operation. By detecting the power supply state of the storage equipment, the reason that normal access cannot be carried out between the storage equipment can be quickly determined, so that equipment switching cannot be triggered when the network fluctuates, the equipment switching time when a real fault occurs is reduced, and meanwhile, the service efficiency of the storage equipment is ensured.

Description

technical field [0001] The present application relates to the field of device control, and in particular to a storage device control method, device, electronic device, and storage medium. Background technique [0002] Active-active is a data disaster recovery solution with two centers in the same city. The two storage devices are connected through optical fibers in the same city, and the two storage devices can undertake business at the same time. After receiving business I / O, the data is copied to the peer storage device through background copying. In this way, data backup and protection can be performed, and storage performance can be fully utilized to achieve business load balance. HyperMetro is a very efficient and reliable data protection solution. One of the requirements is that when one storage device A fails, another storage device B can take over from storage device A to continue business, ensuring that the business will not be interrupted. Achieve business contin...
