COMPUTER SYSTEM AND APPLICATION PROGRAM EXECUTION ENVIRONMENT MIGRATION METHOD

摘要

The present invention makes it possible for a virtual higher-level device disposed on a virtual platform to use prescribed data related to an application. A virtual higher-level device 20 is disposed on a virtual platform 30. A storage system 40 comprises logical volumes 41, 42 for storing prescribed data related to an application program 11. A management computer 50 prepares prescribed logical volumes 43, 44 in the storage system 40 so that the virtual higher-level device 20 is able to use the prescribed data related to the application program, couples a communication interface part of the virtual platform 30 to a communication port part of the storage system 40 so as to make it possible to access the prepared prescribed logical volumes 43, 44 via the virtual platform 30, and further transparently allocates the prescribed logical volumes 43, 44 to the virtual higher-level device 20.
