    摘要: Provided is a storage system capable of starting/stopping a disk drive. At the time of allocating a logical device, it is judged, based on attributes including a purpose of the logical device, whether or not control can be performed in terms of start/stop of an allocation target disk drive to determine an allocation destination disk drive. Further, in the case where access to a specific logical device is stopped due to release of a path definition or other such cause, it is judged whether or not a disk drive corresponding to the logical device can be stopped. When it is judged that the disk drive can be stopped, the disk drive is stopped. When it is judged that the disk drive cannot be stopped, the logical device is migrated to another disk drive that can be stopped, a migration destination disk drive is stopped.

    摘要: Availability of an information system including a storage apparatus and a computer is improved. First and second storage apparatuses execute remote copy of copying data written into a first primary volume from the computer to a second primary volume, at least one of the first and second storage apparatuses executes local copy of copying the data written into the first or second primary volume in a self-storage apparatus to the corresponding first or second secondary volume, and the computer switches the destination of a write request of the data from the first storage apparatus to the second storage apparatus in case of a failure occurring in the first storage apparatus.

    摘要: When a logical volume in a first storage box is transferred to a second storage box, information of an access object such as a network communication protocol possessed by a host which communicates with the first storage box is changed to change a network route for accessing the transferred logical volume. Logical volume transfer is notified from the first storage box to the host by using an ICMP Redirection Error message or the ARP protocol.

    摘要: Availability of an information system including a storage system that performs remote copy between two or more storage apparatuses and a host computer using such storage system is improved. A third storage apparatus including a third volume is coupled to a first storage apparatus, a fourth storage apparatus including a fourth volume is coupled to a second storage apparatus, the first and third storage apparatuses perform remote copy of copying data stored in a first volume to the third volume, the first and second storage apparatuses perform remote copy of copying data stored in the first volume to a second volume, and the third and fourth storage apparatuses perform remote copy of copying data stored in the third volume to the fourth volume.
