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. 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.

摘要： The management system of the present invention is capable of efficiently discovering each apparatus coupled to a communication network. The management server 1 judges a type of an apparatus coupled to a communication network 5 on the basis of service utilization information T1, which is acquired from a discovered device or acquired from a device (an iSNS server 4, for example) having a name server function for resolving an address from a public name, and on the basis of discovery management information prepared beforehand (S1, S2). The management server 1 acquires a communication protocol in accordance with the type of the apparatus from protocol selection rules T3, and attempts authentication of the apparatus by using the communication protocol (S3).

摘要： In a storage system 1, a storage apparatus A having a first pool 1430 including segments as unit storage areas and a storage apparatus B having a second pool 1430 having the same configuration are communicably connected to each other. In the storage system, an external volume identifier is associated with a logical volume 1420 included in the first pool 1430, the external volume identifier being used by a controller 1500 in the storage apparatus B to identify and manage the logical volume 1420 as an external volume 1425 that is a virtual volume in the storage apparatus B. Moreover, a volume identifier 5110 of the logical volume 1420 included in the first pool 1430 is rewritten into the external volume identifier in order to enable the storage apparatus B to utilize the logical volume 1420 created from the first pool 1430.

摘要： If both of LUN security information on storage apparatuses and configuration information on an iSNS server are acquirable, a management server makes reference to configuration situation of the LUN security acquired from a monitoring-target storage apparatus, thereby acquiring iSCSI initiator names which are permitted to access the storage apparatus. Moreover, the management server acquires, from the iSNS server, IP address of an iSCSI initiator name which does not exist on a monitoring-target host out of the iSCSI initiator names, then adding the IP address into monitoring-target nodes. Meanwhile, when an access from the management server to a monitoring-target node becomes impossible for a certain constant time-period due to a reason such that the monitoring-target node has been excluded from the network, the management server is capable of excluding the monitoring-target node from the monitoring targets on a GUI.

摘要： In a management computer which manages a storage system including a main logical volume and subsidiary logical volumes, when the access volume to the main logical volume exceeds a threshold value, a subsidiary logical volume associated with a physical volume having higher input/output performance than the physical volume associated with the main logical volume is selected. When the migration time of the data stored in the physical volume corresponding to the selected subsidiary logical volume is within a prescribed time period, then data stored in the physical volume corresponding to the main logical volume is migrated to the physical volume corresponding to the selected subsidiary logical volume, and the physical volume corresponding to the selected subsidiary logical volume is associated with the main logical volume.

摘要： Conventionally, when a switch virtualizing a storage (storage virtualization switch) is installed in a computer system including an SAN, a host computer, and a storage device, since a port ID of a virtual storage and a port ID of a storage device assigned to the virtual storage are different, the computer system has to be suspended at the time of installation of the storage virtualization switch. The storage virtualization switch installed in the computer system assigns a port ID to a port of a virtual storage generated by the storage virtualization switch so as to be equivalent to a port ID of an existing storage device and, in the case in which the port ID is designated as an access destination by an access request from one computer to the storage device, sends the access request to the virtual storage.

摘要： A management computer manages the pool application information that indicates a pool application for a pool and the application condition information that indicates the condition for the pool application. The management computer calculates an excess storage capacity based on a pool usage status for the pool. The management computer specifies a pool application for the pool and the condition for the pool application based on the pool application information and the application condition information. The management computer judges whether the specified condition is satisfied even in the case in which a storage area having a storage capacity equivalent to or less than the calculated excess storage capacity is deleted from the pool. In the case in which the result of the judgment is positive, the management computer defines a capacity equivalent to or less than the excess storage capacity as an unused capacity.
