处理I/O请求的方法、存储阵列及主机技术

一种I/O请求处理方法，由主机的代理模块执行。所述代理模块在将所述待迁移磁盘的磁盘标识发送至所述阵列标识对应的第二存储阵列，以使所述第二存储阵列根据所述待迁移磁盘的磁盘标识构建所述待迁移磁盘的镜像磁盘。在所述镜像磁盘构建好之后，所述代理模块为上报镜像磁盘的磁盘标识的路径设置虚拟路径信息，并将所述虚拟路径信息上报至所述多路径模块。所述代理模块接收多路径模块通过虚拟路径发送的磁盘标识查询请求，将所述待迁移磁盘的磁盘标识发送至所述多路径模块，以使所述多路径模块将所述虚拟路径作为所述待迁移磁盘的路径进行优先访问路径管理，并将所述虚拟路径设置为所述待迁移磁盘的优先访问路径。

Method, Storage Array and Host for Processing I/O Request

An I/O request processing method is implemented by the agent module of the host. The proxy module transmits the disk identification of the disks to the second storage array corresponding to the array identification, so that the second storage array constructs the mirror disk of the disks to be migrated according to the disk identification of the disks to be migrated. After the mirror disk is constructed, the proxy module sets virtual path information for the path of the disk identifier reporting the mirror disk, and reports the virtual path information to the multipath module. The proxy module receives the disk identity query request sent by the multipath module through the virtual path, sends the disk identity of the disks to be migrated to the multipath module, so that the multipath module manages the virtual path as the path of the disks to be migrated, and sets the virtual path as the priority access of the disks to be migrated. Ask the path.
