    • An information processing system including a plurality of server apparatuses coupled to one another, wherein failover is executed. A management server is coupled to the server apparatuses, and is configured to, when detecting occurrence of a failure in an active server apparatus, execute failover from the active server apparatus to a standby server apparatus after turning on a power supply of the standby server apparatus. The management server is enabled to acquire information on the standby server apparatus after turning on the power supply of the standby server apparatus, turn off the power supply of the standby server apparatus after acquiring the information, and, based on the acquired information, judge whether failover to the standby server apparatus can be executed.
