VIRTUAL MACHINE SYSTEM AND METHOD FOR CONTROLLING THE SAME

摘要

A virtual computer system and a control method thereof are provided to set up a destination LPAR in another physical computer to enable migrating of the LPAR without necessity of setting change of a security function on the RAID apparatus side when a failure occurs in an LPAR on a physical computer under an SAN environment. When completing the reception of the data, the management server displays the completion of reception. Thereafter, the management server determines a destination server module(S301). For example, the management server instructs a hypervisor, which is supposed to generate the LPAR on a destination server module, to receive the server module/hardware configuration information of the server module where the failure occurs and the hypervisor configuration information of the LPAR2(S302). When receiving the configuration information relating to the LPAR2 where the failure occurs(S303), the hypervisor determines whether or not the LPAR can be generated in the destination server module on the basis of the configuration information(S305). The determination will be described later in detail. If the result of the determination satisfies predetermined conditions, the LPAR which takes over the configuration information relating to the LPAR2 of the original server is generated in a destination server(S306). The LPAR4 (124) serves as the LPAR of the destination server. When completing the generation of the LPAR4, the hypervisor transmits the Hypervisor-Agt alert and notifies the completion of generation of the LPAR (S307). When receiving the Hypervisor-Agt alert, the management server transmits an activate command to the hypervisor so as to activate the generated LPAR4(S308). The hypervisor which receives the activate command activates the generated LPAR(S309). Then, the hypervisor transmits the Hypervisor-Agt alert and notifies the completion of activate of the LPAR(S310). The management server which receives the Hypervisor-Agt alert displays an activate status of the LPAR on the display unit(S311).
