A host computerthat manages a container built on an operating system includes a processor. The processoris configured to duplicate a second container based on a container image of a first container, and configure a hardware resource used by the first container such that the hardware resource can also be used by the second container. A nonvolatile storage deviceof the host computerstores container resource information in which the container image of the first container and the hardware resource used by the first container is associated, and the processoris configured to, when duplicating the second container based on the container image of the first container, duplicate the hardware resource associated with the container image of the first container, and configure the duplicated hardware resource such that the duplicated hardware resource can be used by the second container.

The present invention relates to migrating volumes among computers in a computer system. According to the migration method of the present invention, a setting of a storage apparatus is changed so that the volume having been used by the migration source host is accessible by the migration destination host, and then a volume recognition process is performed in the migration destination host. As a result of the volume recognition process, if it is detected in the migration destination host that multiple device files are created in a duplicated manner with respect to a single volume provided by the storage apparatus, the migration destination host deletes the device files created in a duplicated manner leaving one device file.
