Computer system, virtual computer system, computer activation management method and virtual computer activation management method

摘要

A computer system, a virtual computer system and a computer activation management method for each system are disclosed. In the virtual computer system, a virtualization mechanism (220) includes a WWN management table (400) for storing the correspondence between a virtual HBA (210) assignable to each virtual computer (200) and the WWN, and a LPAR activation unit (260) for checking the WWN corresponding to the virtual HBA (210) assigned to the virtual computer (200) based on the WWN management table (400) at the time of activating the virtual computer (200) and in the case where the WWN assumes a value indicating the activation suppression, suppressing the activation of the virtual computer (200). The virtual computer or the computer with the device identification information changeable, if triggered at a timing not intended by the user, can be prevented from being activated.
