摘要： A storage system which has flash memories constituting a storage area and a function of placing and handling the flash memories in on-line mode and off-line mode, and which stores and manages management information of the flash memories in on-line mode. The storage system includes: when some or all of flash memory in on-line mode is placed in off-line mode, creating a management area in off-line mode in the flash memories by moving existing data in an area used as the management area to an area other than the management area; writing the management information of the flash memories to the created management area; and placing the flash memories in off-line mode.

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.

摘要： A management computer collects a usage condition of a volume from a host computer and a storage apparatus at each site, consolidates management thereof, and prevents a volume from duplicating among applications as a copy source. This makes it possible to select a used volume in an application as a copy source without excess or deficiency and to create a copy pair configuration definition without duplication or incompatibility. If a replication environment is constructed in a large-scale storage system, the consolidated management of a usage condition of a volume collected from the host computer and the storage apparatus at each site makes it possible to create a copy pair configuration definition by a task constituted by a plurality of applications.

摘要： A computer system including a first storage system connected to a first host computer, a second storage system connected to a second host computer and a third storage system connected to the first and second storage systems. The second storage system sets transfer setting before an occurrence of a failure, the transfer setting being provided with a dedicated storage area to be used for transferring data to the third storage system by asynchronous copy in response to a failure at the first host computer. Before the start of data transfer between the second storage system and third storage system to be executed after an occurrence of the failure, the second storage system checks the dedicated storage area, data transfer line and transfer setting information, and if an abnormal state is detected, this abnormal state is reported to the host computer as information attached to the transfer setting.

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： The management burden of a replication administrator is alleviated and the monitoring burden is reduced in a storage system. In a large-scale storage system configured across a plurality of sites, a management computer managing the storage system collects configuration information of a volume group such as the copy pair status information from a host computer of the respective sites including a primary site and a remote site, and analyzes the collected information. When a failure or a disaster occurs and the primary site and the remote site are switched and the management computer detects a change in the configuration of the volume group, and appropriate switches the monitoring configuration upon determining the configuration of the detected change.

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.
