摘要：
The present invention efficiently changes a volume size while maintaining a copy pair as-is. A PVOL and a SVOL #1 are in a pair state and are synchronized. The PVOL and a SVOL #2 are in a restore state. Upon instruction of expansion of the size of the PVOL, the size of a copy-destination SVOL #1 is first expanded, the size of the PVOL is then expanded, and the size of the SVOL #2 is lastly expanded. In the case of a PSUS state, only the size of the PVOL is expanded, and the size of the SVOL is left as-is.
