Abstract
To more effectively eliminate a resource imbalance among storage apparatuses, and shorten the time required for elimination in a computer system including a plurality of storage apparatuses and a computer. In a computer system including a plurality of storage apparatuses that provide a volume to a computer and a storage management device that manages the plurality of storage apparatuses, in a case where there is an instruction to create a new volume, the storage management device compares a distribution of feature amounts of all volumes provided by each storage apparatus and a distribution of feature amounts of all volumes in a case of providing a newly created volume in each storage apparatus, and instructs a storage apparatus having a largest difference in the distributions of the feature amounts to create a volume.
