摘要： The present invention efficiently changes a volume size while maintaining a copy pair as-is. A PVOL and a SVOL #1 are in a pair state and are synchronized. The PVOL and a SVOL #2 are in a restore state. Upon instruction of expansion of the size of the PVOL, the size of a copy-destination SVOL #1 is first expanded, the size of the PVOL is then expanded, and the size of the SVOL #2 is lastly expanded. In the case of a PSUS state, only the size of the PVOL is expanded, and the size of the SVOL is left as-is.

摘要翻译： 本发明有效地改变卷大小，同时保持副本对。 PVOL和SVOL＃1处于成对状态并同步。 PVOL和SVOL＃2处于恢复状态。 在指示扩大PVOL的尺寸时，首先扩大复制目的地SVOL＃1的大小，然后扩大PVOL的大小，并且最后扩大SVOL＃2的大小。 在PSUS状态的情况下，仅扩大PVOL的尺寸，SVOL的大小保持原样。

摘要： When an event occurs in a storage system that is not recognized by a host, it is not possible to recover data at the point before and after this event. Provided is a storage system including a first storage area storing data to be used by a computer, and a second storage area for storing updated data and its update log information when there is an update request from the computer to the first storage area. This storage system monitors its own storage system and detects an event, and creates a recovery point and its update log information based on the event. When the storage system receives a recovery command at a certain recovery point, it recovers data of the first storage area at the time of recovery point by writing, in a replication storage area at a certain point of the first storage area, update data up to the recovery point among the update data stored in the second storage area.

摘要： The present invention creates a pool comprising tiers corresponding to the performance of logical volumes.A first storage apparatus either acquires or measures the performance of multiple external pool volumes of an external storage (S1711 through S1714), and creates a pool volume group based on the performance of the external pool volumes (S1715, S1716). The rank order of a tier is decided in accordance with the performance of each pool volume group (S1717, S1718). This makes it possible to relatively easily create a pool comprising multiple appropriate tiers that are suited to the current situation.

摘要： A host I/F unit has a management table for managing an MPPK which is in-charge of the control of input/output processing for a storage area of an LDEV, and if a host computer transmits an input/output request for the LDEV, the host I/F unit transfers the input/output request to the MPPK which is in-charge of the input/output processing for the LDEV based on the management table, an MP of the MPPK performs the input/output processing based on the input/output request, and the MP of the MPPK also judges whether the MPPK that is in-charge of the input/output processing for the LDEV is to be changed, and sets the management table so that an MPPK which is different from the MPPK that is in-charge is to be in-charge of the input/output processing for the LDEV.

摘要： A storage system 200 has a storage device 240 providing a plurality of logical volumes 250 used as data storage areas of a host 100 and a plurality of MPPKs 210 executing data IO processes for the logical volumes 250 from the host 100 and, when it is determined whether the MPPKs 210 correlated with the logical volumes 250 must be changed based on a storage function such as local copy set for the logical volumes 250, if it is determined that the change is necessary, the usage rates of processors 212 of the MPPKs 210 are acquired and compared with each other and if it is determined that the comparison result satisfies a predetermined condition, the process cost for the logical volumes 250 is calculated for each of the responsible MPPKs 210 to determine the destination MPPK 210 such that the costs of the MPPKs 210 are equalized.
