PROBLEM TO BE SOLVED: To automatically control relevant I/O priority setting in transferring an application between servers in a SAN (Storage Area Network) environment. SOLUTION: When a virtual port created for a physical port on a first storage control unit is transferred to another physical port, such as in the same storage control unit or on another storage control unit, priority settings on the first physical port and storage control unit are checked and transferred with the virtual port to the other physical port to prevent competition for priority by virtual ports at the destination physical port. Similarly, priority settings assigned to volume groups may also be transferred when a volume group is transferred to another physical port within a storage control unit or to a different storage control unit.
