    • When a storage device initiates a change in its file system, it locally stores it for future update of the file system. When the host device sends a command to the storage device, the storage device responds to it by commencing a synchronization process during which the two parties coordinate the update of the file system with the stored change. If there are no file system changes pending in the host device, the storage device gets permission from the host device to update the file system with the change and, then, the host device reads the updated file system from the storage device. If there are file system changes pending in the host device, the host device updates a representation of the file system residing in the host device, causes the storage device to make the same changes, and then the storage device initiated change, in the file system. Lastly, the host device receives information from the storage device regarding the changes initiated by the storage device.
    • 当存储设备启动其文件系统的更改时,本地存储设备会将其存储以供将来更新文件系统。 当主机设备向存储设备发送命令时,存储设备通过开始同步过程来对其进行响应,在该同步过程期间双方协调文件系统的更新与存储的更改。 如果主机设备中没有挂起文件系统更改,存储设备将从主机设备获得许可,以更新文件系统,然后主机设备从存储设备读取更新的文件系统。 如果主机设备中存在文件系统更改挂起,则主机设备更新驻留在主机设备中的文件系统的表示,使存储设备进行相同的更改,然后存储设备发起更改,在文件系统中 。 最后,主机设备从存储设备接收关于由存储设备发起的改变的信息。
