1. A storage control device that controls a physical storage device in a storage system, the storage control device comprising:
a memory configured to store a management table; and a processor configured to perform operations including: receiving a command from the storage system including the physical storage device and a virtual storage device, the physical storage device configured to store data in a physical volume, the virtual storage device configured to intervene between a host device and the physical storage device and store data to be transmitted and received between the host device and the physical storage device as a virtual portable volume; registering, when determining that the command is an export-corresponding write command from the virtual storage device, identification information of a third physical volume specified by the export-corresponding write command in the management table; comparing, when the command is an ejection command indicating an outside management of a first physical volume specified by the ejection command, the identification information of the first physical volume with the identification information of the third physical volume in the management table; and performing data protection setting on the first physical volume when the identification information of the first physical volume accords with the identification information of the third physical volume in the management table.
