ABSTRACT:
Provided is a method of managing a computer system including a plurality of storage systems and a plurality of management appliances for managing the plurality of storage systems. A first management appliance and a second management appliance hold an identifier of a first storage system and management data obtained from the first storage system. The method includes the steps of: selecting a third management appliance from the plurality of management appliances when a failure occurs in the first management appliance; transmitting the identifier held in the second management appliance from the second management appliance to the selected third management appliance; and holding the identifier transmitted from the second management appliance in the selected third management appliance. Thus, it is possible to prevent, after failing-over due to an abnormality of a maintenance/management appliance, a single point of failure from occurring to reduce reliability of the maintenance/management appliance.
