The setting of the redundancy of the set path in the first computer system a second computer reflect computer system and methods

摘要

PPROBLEM TO BE SOLVED: To reflect path redundancy set by a first computer system in a second computer system without placing much of burden on the individual. PSOLUTION: Mapping management information denoting the mapping of a first host and first host volume and a second host and second host volume is prepared beforehand. First-path-redundancy information, which is related to the redundancy of the first path of the first host volume, is acquired, and a second host volume and second host mapped to this first host volume and the first host thereof are specified by referencing the mapping management information. The redundancy of a second path, which links the specified second host volume and a second storage volume, is determined based on the first-path-redundancy information. Second-path-redundancy information, which is related to the determined second path redundancy, is output to set the determined second-path-redundancy in the specified second host.
