Abstract:
1. A virtual computer system comprising a plurality of physical computers including first and second physical computers, a management apparatus that is connected to the plurality of physical computers via a network to manage the physical computers and logical partitions, and a monitoring apparatus managing the plurality of physical computers, and allows OSs to operate by generating the logical partitions on the physical computers, wherein the monitoring apparatus includes status detection means for detecting that a status change has occurred in the first physical computer or the first logical partition formed therein, the first physical computer includes: a first physical adapter for communicating with the logical partition; and first management means for managing configuration information of the first physical partition and a virtual identifier as an identifier assigned to a logical adapter provided in the first logical partition, the management apparatus includes: means for accepting notification of the status change occurrence from the status detection means to receive the configuration information of the first logical partition and the virtual identifier from the first management means; and means for determining a substitute second physical computer to transmit the configuration information of the first logical partition and the virtual identifier to the second physical computer, the second physical computer includes: a second physical adaptor for communicating with the logical partition; means for receiving the configuration information of the first logical partition and the virtual identifier transmitted from the management apparatus; means for determining, on the basis of the configuration information of the first logical partition, whether or not the second logical partition can be generated on the second physical computer; and means for generating the second logical partition on the basis of the virtual identifier upon detection by the determination means that the second logical partition can be generated, the configuration information of the first logical partition includes information of the first physical adapter, and in the means for generating the second logical partition, a logical adapter is provided in the generated second logical partition and the virtual identifier is assigned to the logical adapter provided in the second logical partition.
