For each of N active servers (N being an integer equal to or larger than 2), a management system performs, on at least one of M standby servers (M being an integer equal to or larger than 2), a full test for determining whether a failover is executable by performing a failover from the active server to the standby server, and performs, on at least one of the standby servers that is different from the standby server on which the full test is performed, a simplified test for determining whether the failover is executable without performing the failover from the active server to the standby server, the number of standby servers on which the simplified test is performed being larger than the number of standby servers on which the full test is performed. |

1. A management system comprising:
an interface device coupled to a server system including N active servers (N being an integer equal to or larger than 2) and M standby servers (M being an integer equal to or larger than 2), and a storage system that provides a plurality of LUs (Logical Units) to the N active servers; and a processor coupled to the interface device and a storage device, the storage device being configured to store server management information including information indicating for each server whether the server is an active server or a standby server, the processor being configured to determine a plurality of server combinations based on the server management information, each of the server combinations being a combination between any one of the N active servers and any one of the M standby servers, the processor being configured to execute diagnosis processing for performing a test to determine whether a failover is executable for each of the plurality of server combinations, the test being a full test for determining whether the failover is executable by performing a failover from the active server to the standby server or a simplified test for determining whether the failover is executable without performing the failover from the active server to the standby server, and in the diagnosis processing, the processor being configured to perform, for each of the N active servers, the full test on at least one of the standby servers, and the simplified test on at least one of the standby servers that is different from the standby server on which the full test is performed, the number of standby servers on which the simplified test is performed being larger than the number of standby servers on which the full test is performed. |
