摘要： This invention provides, when optimizing a configuration of a storage system using a pool, an optimal configuration while ensuring a policy set by an administrator, the policy concerning a power saving performance, a response performance, or the like. The management computer sets, according to the set policy, priorities to volumes held by a storage subsystem, and reserves volumes satisfying the capacity of the pool, in descending order of the priority. Only some of the reserved volumes are registered for the pool in descending order of the priority. At this time, it can be guaranteed that a host computer makes no access to the volumes which have not been registered for the pool, and therefore the sleep state is set to physical drives forming the volumes or to a controller controlling the physical drives.

摘要： A computing system and an exclusive access control method are provided for preventing degraded performance of a network caused by exclusive access control, and for permitting a computer to exclusively access a storage area irrespective of whether a storage has an exclusive access control function. In the computing system in which a plurality of computers and an external storage device storing shared data are connected through a relay, exclusive access control is executed by a device other than the storage. Specifically, the relay having a virtualizing function is instructed to execute exclusive access control. The relay has information indicating whether a storage area on the storage is an exclusive access area, so that the relay determines based on this information whether an access request received from a computer requests an access to an exclusive access area, and executes exclusive access control when it is an access request.

摘要： In a computer system, to enable a second computer to take over control of copying of data within the computer system, from a first computer that normally controls copying of data. The second computer selects from a plurality of storage systems a storage system to be accessed in order to acquire sub system pair information, and acquires sub system pair information from the selected storage system. Based on the acquired sub system pair information, the second computer generates system pair information that includes copy pair information relating to a plurality of storage areas belonging to the plurality of storage systems. The second computer initially selects a storage system directly linked to the second computer, and subsequently sequentially selects a storage system based on the acquired sub system pair information.

摘要： Transfer of data and replication of data among several storage devices are executed without imposing a load on the computer connected to the storage system. For example, a first host computer monitors usage rates of transfer groups TG11, TG12 and physical path usage rate on a storage device interconnect physical path 50, and when either a usage rate or physical path usage rate goes above a predetermined value, issues to the first storage device 20 an instruction to allocate a reserved volume R11, R12. The first host adaptor 21 receiving the reserved volume R11, R12 allocation request allocates reserved volume R11 to transfer group TG1, whereby a virtual transfer volume is formed by transfer volume T11 and the reserved volume R11 allocated thereto. As a result, capacity of the virtual transfer volume is increased by the equivalent of the reserved volume R11 capacity, so that additional transfer frames may be stored.
