摘要： When there is a change in a group of volumes managed by a host computer, data duplication processing is immediately carried out against the changed volume. The host computer includes a volume-managing portion, a data duplication-controlling portion which executes the data duplication of data stored in a volume in a main data center, and a data duplication storing portion which stores data necessary for the data duplication. The data duplication-controlling portion compares data held by the volume-managing portion with the data in the data duplication storing portion, and updates the data in the data duplication storing portion based on the data held by the volume-managing portion.

摘要： When migrating data stored in a storage region assigned to a volume to another storage region, the connection status of the host computer and volume is confirmed. When the host computer and volume are connected, the maximum capacity of the volume requested by the host computer is reserved so that it is exclusively secured in another storage region to which data is to be migrated, and when the host computer and volume are not connected, the current capacity of the volume is reserved so that it is exclusively secured in another storage region.

摘要： In a data processing system having a storage system and a management computer for managing the storage system, the management computer has an access right setting request unit for transmitting, to the storage system, a request to set a right to access a designated logical volume in response to a predetermined external input. The storage system also has: a control unit for dynamically expanding, as necessary based on an access request from the host computer, the capacity of a first type logical volume by dynamically assigning storage areas in units of segments of predetermined size thereto; and an access right setting unit for setting, in response to a request to set a right to access the first type logical volume from the management computer, a designated access right for each segment assigned to the first type logical volume.

摘要： Conventionally, it has been impossible to choose storage subsystems for selective implementation of I/O delay to prevent buffer from overflowing during remote copy. According to this invention, in a management computer that manages serially connected plural storage subsystems in a computer system, the computer system having a host computer to write data in the storage subsystems, the plural storage subsystems each have one or more logical volumes where data is stored and a buffer where data is stored temporarily, the logical volume of one of the storage subsystems and the logical volume of another of the storage subsystems form a pair for remote copy, and the management computer observes the usage of each buffer and issues, when the usage of the buffer exceeds a given threshold in a first storage subsystem, a command to delay executing write processing to the storage subsystems that are upstream of the first storage subsystem.

摘要： A dump information acquiring method and a system recovery method for a computer system using a virtual memory, the methods being used when fault occurs in the computer system. The computer system has a plurality of external storage units used as a paging device unit for holding the contents of the virtual memory to be paged out from a main memory. During the normal operation, an external storage unit selected from the plurality of external storage units is used as the paging device unit. When fault occurs, a program for acquiring dump information operates to output the contents of the main storage at the time of the fault occurrence to a dump file. The identifier of the external storage unit set to definition information for defining the external storage unit used as the paging device unit is changed from the identifier of the external storage unit used as the page device unit to the identifier of another external storage unit. Thereafter, the computer system is restarted. The contents of the virtual memory held in the paging device unit at the time of the fault occurrence are output to the dump file by a program executed in a background of a job process of the current computer system or by a program executed by another computer system.
