    摘要: Provided are a method, system and program from managing failures in a mirrored system. A copy relationship between primary and secondary storage locations, wherein updates to the primary storage locations are copied to the secondary storage locations. A failure is detected preventing an application from writing updates to the primary storage locations. A failure message is received for the application in response to detecting the failure, wherein the failure message is not provided to the application. The copying of updates to the primary storage locations to the secondary storage locations is suspended. The failure message is provided to the application in response to suspending the copying.

    摘要: Provided are a method, system, and program for remote copying of updates to primary and secondary storage locations subject to a copy relationship. A first copy relationship is established between first and second storage locations in a first storage system and second storage system, respectively, wherein updates to the first storage locations are copied to the second storage locations. A second copy relationship is established between the first storage locations in the first copy relationship and third storage locations in a third storage system, wherein updates to the first storage locations are indicated in a first bitmap. A suspended third copy relationship is established between the second storage locations in the first copy relationship and the third storage locations, wherein updates to the second storage locations are indicated in a second bitmap. Updates are copied from the first or second storage locations to the third storage locations, wherein the first or second bitmap is capable of being used to determine updates for the first or second storage locations to copy to the third storage locations.

    摘要: Provided are a method, system, and program for maintaining consistency when mirroring data using different copy technologies. Update groups having updates to primary storage locations are formed using a first copy technology. The updates in the update groups are copied to secondary storage locations. Update groups having updates to primary storage locations are formed using a second copy technology, wherein the updates in the update groups are copied to secondary storage locations. Indication is made in a data structure of a time of an update in response to including the update in one of the update groups formed using the first copy technology. Indication is also made in the data structure of a time of the update group formed using the second copy technology.

    摘要: Provided are a method, system, and program for consolidating session information for a cluster of sessions in a coupled session environment. Information for each of a plurality of sessions comprising a cluster is stored in a memory of a processor session. Each session associates at least one primary system and at least one secondary system, wherein within each session, updates are copied from the at least one primary system to the at least one secondary system. The session information in the memory for the plurality of sessions is processed to generate consolidated session information for the cluster based on the session information for the sessions in the cluster. The consolidated session information for the cluster is written to a master data set maintaining information for sessions.

    摘要: Techniques are provided for distributing data. It is determined that a source storage device is becoming a bottleneck. One or more blocks to be moved from the source storage device to one or more other storage-devices are identified. The one or more other storage devices are selected. Copy services are used to move the blocks from the source storage device to the one or more other storage devices. A metadata store is updated with locations of the blocks that have been moved.

    摘要: Provider are a method, system, and program for maintaining data in a distributed computing environment. Data is stored at a primary storage site. A data structure is processed indicating an association of data sets in the stored data, secondary storage sites, and update frequencies. In response to processing the data structure, a determination is made of one of a plurality of secondary storage sites and a determination is made of at least one data set to transmit to the determined secondary storage site at an update frequency. The determined data set is transmitted to the determined secondary storage site according to the update frequency.
