Abstract
A method and a system for configuring mirrors of virtual storage devices in a virtual host includes obtaining a topology connection relationship between the virtual storage devices to be configured with mirrors and the virtual host, where the topology connection relationship is a hierarchical relationship in a tree shape with the virtual host as a root node and the virtual storage devices to be configured with mirrors as leaf nodes, and configuring the mirrors of the virtual storage devices to be configured with mirrors in the virtual host according to the obtained topology connection relationship. The method and the system for configuring mirrors of virtual storage devices in a virtual host can increase reliability.
