Method and apparatus to simplify HA solution configuration in deployment model

摘要

A method, device and system for generating an HA group according to a user's HA requirement by retrieving an applicable HA pattern, according to a result of HA requirement analysis on the user's HA requirement; generating an initial HA group based on the retrieved HA pattern; performing context rebuilding on a member unit in the initial HA group to obtain a preliminarily configured HA group; generating a member unit based HA group variant for the preliminarily configured HA group according to an HA group redundancy obtained from the user's HA requirement; and performing structure configuration and attribute configuration on a member unit in the generated HA group variant to obtain an HA group that meets the user's HA requirement.
