摘要： A computer system in an embodiment comprises a storage apparatus, a host computer, and a copy control program. The storage apparatus performs copy operations of volumes allocated to a guest OS of the host computer. The copy control program obtains volume information of the guest OS from a VM control program at a given time. The control program compares the information with previous volume information of the guest OS and performs volume copy control for the guest OS in accordance with the comparison result. This process achieve appropriate copy operations even if the association relationship between the guest OS and volumes is changed during system operation.

摘要： A data storage or management method is provided which allows both a content object-based access and a file-based access. A first request for storing a content object in accordance with the processing of an application program executed in a host is sent to an object archive control functionality executed in the host, an intermediate server, or a storage apparatus. The object archive control functionality generates an object identifier corresponding to the content object received in response to the first request, a directory name corresponding to the object identifier, and a plurality of file names corresponding to a plurality of fields contained in the content object. The storage apparatus stores a directory having the directory name and the plurality of files having the plurality of file names in accordance with the second request.

摘要： A copy source storage controller received write data added with a time and issued from a host computer transfers the write data with the time to a copy destination storage controller. If there are a plurality of copy destination storage controllers, a representative copy destination storage controller compares times of write data copied to the plurality of copy destination storage controllers, and writes the write data in copy destination logical volumes in the sequential order of time. The representative copy destination storage controller judges that integrity of the write data is established, if a communication procedure is established with the copy destination storage controller and if the statuses of the copy source/destination logical volumes are coincident. In remote copy which guarantees integrity of write data and traverses a plurality of storage controllers, it is possible to judge at an optional time point whether integrity of write data can be guaranteed.
