    摘要： There is provided a management computer comprising a processor and a storage resource. The processor acquires information on a type of the first management object and the second management object; traces association from the type of the second management object to the type of the first management object; generates a metarule including a condition part and a conclusion part; generates a method of acquiring information on a topology constructed by the association from the type of the second management object to the type of the first management object based on a method of the trace from the type of the second management object to the type of the first management object; acquires the information on the topology based on the generated method; generates an expanded rule from the generated metarule and the acquired information on the topology; and analyzes a detected new failure based on the generated expanded rule.

    摘要： In analyzing an elaborate computer system which requires large-scale or numerous event propagation models, a law-of-causality matrix gains size, so that significant amount of storage resources has been used in a management computer. To solve such a problem, the management computer to manage the computer system stores topologies, event propagation models, and causality information including one or more causal relations in the storage resources, determines, when the management computer analyzes or detects an event, whether a causal relation has already been created for the event to be analyzed, and creates the causal relation based on a topology and event propagation models, if not yet.

    摘要： A management system manages a computer system including a plurality of types of managed objects. A storage device of the management system stores one or more meta-rules indicating a correspondence relationship between a cause event and one or more influence events, as well as change frequency information indicating a change frequency for each relation between the types of managed objects. A control device of the management system divides, on the basis of the change frequency information, a first relation group indicating a connection configuration within a rule for a first meta-rule, into a second relation group configured by a relation in which a change frequency is equal to or larger than a predetermined value, and a third relation group configured by a relation in which a change frequency is less than a predetermined value, and divides a first meta-rule into a second meta-rule in which the connection configuration indicated by the second relation group is the connection configuration within a rule, and a third meta-rule in which the connection configuration indicated by the third relation group is the connection configuration within a rule.

    摘要： A management computer stores, in a memory, configuration information which indicates, by mapping, a virtual volume recognized by a host computer and a logical volume provided by a storage apparatus, and backup history information which manages a data backup history on a per virtual volume basis. Upon receiving a data backup request designating a virtual volume, the CPU of the management computer refers to the configuration information and acquires information of the logical volume mapped with the designated virtual volume. The CPU additionally refers to the backup history information and determines whether the logical volume currently mapped with the virtual volume coincides with the logical volume associated with the stored history. When it is determined that the mapped logical volume differs from the logical volume associated with the stored history, the CPU performs control to implement a differential backup between the logical volumes.

    摘要： A management computer stores, in a memory, virtual logical volume management information showing information on virtual logical volumes provided to a host computer by a storage device, and pool management information showing information related to a use status of pools. The management computer acquires performance information related to an access to the storage device from the host computer, determines whether the acquired performance related to the access satisfies a predetermined first required performance, or not, and specifies any virtual logical volume which is a cause of the state based on the virtual logical volume management information if the first required performance is not satisfied. The management computer calculates a capacity consumption trend of the real area included in each pool based on the pool management information, creates a countermeasure for satisfying the first required performance implementable after a given time, and outputs the countermeasure to an output device.
