Abstract
A storage control apparatus includes a processor. The processor is configured to store, during a normal operation mode, first data as a first logical volume in a storage section of a first virtual storage device. The first data is transmitted and received between a first host device and a physical storage device. The physical storage device stores data in a physical volume. The first virtual storage device is connected to the physical storage device during the normal operation mode. The processor is configured to serve, during a data migration mode, as a pseudo host device connected to a second virtual storage device. The pseudo host device accesses the second virtual storage device to read out second data of a second logical volume stored in the second virtual storage device. The first virtual storage device is connected to the second virtual storage device during the data migration mode.
