1. A computer switching method to be performed by a computer system including a plurality of computers, a storage system, and a management computer,
the plurality of computers each including: a first processor; a first memory coupled to the first processor; and a first I/O device coupled to the first processor, the management computer including: a second processor; a second memory coupled to the second processor; and a second I/O device coupled to the second processor, the storage system including: a controller; a plurality of storage devices coupled to the controller; and a plurality of ports coupled to the controller, for respectively coupling the storage system to the plurality of computers, the plurality of computers including: a plurality of first computers for executing a service; and a plurality of second computers for taking over the service executed by each of the plurality of first computers, the storage system providing a logical storage device generated by using storage areas of the plurality of storage devices to each of the plurality of first computers, the logical storage device including a first logical storage device which is a storage area for storing data necessary for the service, the computer switching method including: a first step of detecting, by the management computer, a switch trigger for the service from one of the plurality of first computers to one of the plurality of second computers; a second step of transmitting, by the management computer, a first generation request for instructing the storage system to generate a second logical storage device which is a virtualized storage area to be provided to the one of the plurality of second computers; a third step of generating, by the storage system, the second logical storage device for the one of the plurality of second computers based on the first generation request; a fourth step of generating, by the management computer, first change information for mapping the first logical storage device for storing the data necessary for the service executed by the one of the plurality of first computers to the second logical storage device for the one of the plurality of second computers, and transmitting a first change request including the generated first change information to the storage system; a fifth step of mapping, by the storage system, the first logical storage device for storing the data necessary for the service executed by the one of the plurality of first computers to the second logical storage device for the one of the plurality of second computers based on the first change information; and a sixth step of booting, by the management computer, the one of the plurality of second computers. |
