Abstract:
1. A data relay device comprising: a memory; and a processor coupled to the memory, wherein the processor executes a data relay process comprising: receiving a virtual machine identifier representing a virtual machine of a migration target, a path identifier representing a communication path through which the virtual machine performs communication and a setting request of a port profile from a server connected with the data relay device; determining whether a storage device, which stores a virtual machine identifier of a virtual machine operated by the server connected with the data relay device and a port used by the virtual machine, stores the virtual machine identifier received by the receiving in association with another port; and transferring the setting request of the port profile to a data relay device of an upper level higher than the data relay device, wherein the transfetting includes determining the communication path represented by the path identifier received by the receiving and the data relay device is in the determined communication path, when it is determined by the determining that the received virtual machine identifier is not stored in association with the other port.
