Abstract
In the computer system including a host computer and a storage system, the storage system includes a physical disk and a disk controller, and provides a storage area of the physical disk as at least one logical unit. The processor obtains, at a first time point and a second time point different from the first time point, a relation between a logical path and a component through which the logical path passes, stores, as logical path connection information, the relations obtained at the first time point and the second time point, refers to the logical path connection information to compare the logical paths existing at the first time point and the logical paths existing at the second time point with each other, and specifies the logical path which does not exist at the second time point among the logical paths existing at the first time point.A1
