Management computer and method of managing data storage apparatus

Abstract

In a computer system having hierarchically-arranged data storage apparatuses, a management computer provides information required for performing operation on the data storage apparatuses. Through a network for collecting management information, storage area information and hierarchy information are collected from each data storage apparatus. Management relation information is created using the collected storage area information and the collected hierarchy information together with programs for respectively managing the data storage apparatuses, and, the created management relation information is held. Based on the created management relation information, a display screen expressing the hierarchy of the data storage apparatuses is created. Further, responding to operation by a user, a return considering the hierarchy is displayed.

1 . A management computer connected through a second network to data storage apparatuses that are connected to computers through a first network, said management computer comprising: 
 a storage area information collecting module which collects respective pieces of storage area information from said data storage apparatuses connected through the second network, wherein each piece of storage area information relates to storage areas provided by a data storage apparatus concerned;    a hierarchy information collecting module which collects respective pieces of hierarchy information from said data storage apparatuses connected through said second network, wherein each piece of hierarchy information indicates hierarchy among data storage apparatuses held by a data storage apparatus concerned; and    a management relation information creation module which sets hierarchy among said data storage apparatuses to create management relation information, based on said pieces of storage area information and said pieces of hierarchy information collected in said storage area information collecting module and said hierarchy information collecting module.
