Abstract
A storage system 200 has a storage device 240 providing a plurality of logical volumes 250 used as data storage areas of a host 100 and a plurality of MPPKs 210 executing data IO processes for the logical volumes 250 from the host 100 and, when it is determined whether the MPPKs 210 correlated with the logical volumes 250 must be changed based on a storage function such as local copy set for the logical volumes 250, if it is determined that the change is necessary, the MPPK 210 after the change is determined such that the logical volumes 250 are correlated with the same MPPK 210.
