SYSTEM REDUNDANCY VERIFICATION METHOD AND COMPUTER SYSTEM

摘要

A system redundancy verification method, which is to be executed in a computer system, the computer system comprising a first computer, a second computer, a storage system, and a management computer, the system redundancy verification method including: a step of obtaining, by the management computer, first hardware information on the first computer and second hardware information on the second computer; a step of obtaining, by the management computer, first storage area information on the storage area; a step of obtaining, by the second computer the second storage area information from the storage system, and a step of comparing, by the management computer, the first hardware information and the first storage area information with the second hardware information and the second storage area information, and determining whether a failover is implementable between the first computer and the second computer.

主权项

1. A system redundancy verification method, which is to be executed in a computer system,
the computer system comprising at least one first computer, at least one second computer, a storage system, and a management computer for managing the at least one first computer and the at least one second computer, the at least one first computer including a first processor, a first memory coupled to the first processor, and a first I/O interface coupled to the first processor, the at least one second computer including a second processor, a second memory coupled to the second processor, and a second I/O interface coupled to the second processor, the storage system including a disk controller and a plurality of storage media, the disk controller including at least one controller each including at least one port, the management computer including a third processor, a third memory coupled to the third processor, and a third I/O interface coupled to the third processor, the at least one first computer being configured to execute a service, the at least one second computer being configured to take over the service, in a case where a failure occurs on the at least one first computer, the storage system being configured to provide the at least one first computer with a storage area for storing data necessary for executing the service, the system redundancy verification method including: a first step of obtaining, by the management computer, first hardware information on a hardware configuration of the at least one first computer and second hardware information on a hardware configuration of the at least one second computer; a second step of obtaining, by the management computer, first storage area information on the storage area provided to the at least one first computer; a third step of transmitting, by the management computer, an instruction to obtain second storage area information on the storage area provided to the at least one first computer to the at least one second computer; a fourth step of obtaining, by the at least one second computer, in a case of receiving the obtaining instruction, the second storage area information from the storage system, and transmitting the obtained second storage area information to the management computer; and a fifth step of comparing, by the management computer, the obtained first hardware information and the obtained first storage area information with the obtained second hardware information and the obtained second storage area information, and determining whether a failover is implementable between the at least one first computer and the at least one second computer based on a result of the comparison.
