Data processing method and device and medium

The invention relates to the field of data storage, and discloses a data processing method and device and a medium, which are applied to a processor connected with shared storage equipment, and the data processing method comprises the following steps: when a data operation instruction is obtained, obtaining state information of the shared storage equipment stored in a state storage unit, the state storage unit is a device connected with each processor; whether the state information meets a preset condition or not is judged, and the preset condition is a condition determined by analyzing the data operation instruction; and if the preset condition is met, executing the data operation instruction. Therefore, according to the technical scheme provided by the invention, the working state information of the storage equipment is acquired through the state storage unit connected with the shared storage equipment, so that whether the data operation instruction is executed or not is judged, a processor and a GPIO (Gene
