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： A method, apparatus, and article of manufacture for performing a point-in-time backup using a snapshot function. Work space on a work virtual volume is obtained to hold the snapshot copy of the source data being copied from a source virtual volume. Updates to the source virtual volume are suspended during the snapshot function, so as to provide a logically consistent view of the source virtual volume at a common point in time. Pointers are copied from a virtual track table of the source virtual volume to a virtual track table of the work virtual volume without actually moving any data on data storage devices referenced by those pointers. As a result, the snapshot function provides a method for copying the source virtual volume to the work virtual volume very quickly. Upon completion of the snapshot function, updates to the source virtual volume may be resumed. Subsequently, a backup is performed in the usual manner, except that the backup retrieves the source data from the work virtual volume rather than the source virtual volume.

摘要： Provided are a computer program product and system for maintaining mirror and storage system copies of volumes at multiple remote sites. A first server maintains a mirror copy relationship between a first storage system at a first site and a second storage system at a second site. The first server performs a first point-in-time copy operation from the first storage system to a first storage system copy, wherein the data for the first storage system copy is consistent as of the determined point-in-time. The first server transmits a command to a second server to create a point-in-time copy of the second storage system. The second server processes mirror data transferred from the first server as part of the mirror copy relationship to determine when to create a second point-in-time copy. The second server performs the second point-in-time copy operation.

摘要： An approach to synchronization of logical copy relationships on a local site with those on a remote site that is a mirror. A withdraw command is received on the local site for logical copy relationships between local source tracks and local target tracks. The withdraw command is executed and sent to a remote site buffer, from which it will be transferred to the remote site. Change indicators are set for the at least one local track in the affected logical copy relationships. If the withdraw command is lost from the remote site buffer, the remote site buffer will be rebuilt using the change indicators. By setting change indicators for local tracks in a withdrawn logical copy relationship (even if the data in local tracks hasn't changed), the remote counterparts to these tracks on the remote site will be rewritten, resulting in withdrawal of the logical copy relationship there even if the withdrawal command was never sent to the remote site.

摘要： Methods, computing environments, and computer program products are provided for replicating data. Point-in-time copy parameters are generated at a primary host site. A side file entry having the point-in-time copy parameters and a track information field (TIF) associated with the point-in-time copy parameters is generated. The side file entry is transferred to a secondary host site. A point-in-time copy process is performed at the secondary host site based on the point-in-time copy parameters and the TIF.

摘要： A first command is sent from a primary host system to a primary storage controller device, specifying that a first primary volume is to be flash-copied to a second primary volume. Flash-copying provides for completion of copying the first primary volume to the second primary volume to be signaled prior to data on the first primary volume being physically copied to the second primary volume. A first state of the first primary volume and the second primary volume is verified by the primary storage controller device to determine whether the first state permits flash-copying of the first primary volume to the second primary volume. A first query is sent from the primary storage controller device to a secondary host system, requesting whether a first secondary volume can be flash-copied to a second secondary volume. The first and second secondary volumes asynchronously mirror the first and second primary volumes, respectively.

摘要： A primary storage controller is configured to communicate with a secondary storage controller via a system data mover. In response to receiving a command to perform a point in time copy of a source volume of the primary storage controller to a target volume of the primary storage controller, a determination is made as to whether the target volume of the primary storage controller is a source for an asynchronous data replication operation, initiated by the system data mover, between the primary storage controller and the secondary storage controller. In response to determining that the target volume of the primary storage controller is the source for the asynchronous data replication operation, initiated by the system data mover, the point in time copy of the source volume of the primary storage controller to the target volume of the primary storage controller is performed.

摘要： A method for managing storage functions in a data replication environment is disclosed. In one embodiment, such a method includes continually monitoring for changes to a storage configuration at a secondary site. Upon detecting changes to the storage configuration at the secondary site, the method transmits remote metadata describing the changes to the primary site and stores the remote metadata at the primary site. The method then initiates a storage management function at the primary site which is mirrored to the secondary site. In order to perform the storage management function, the method reads the remote metadata at the primary site to determine the storage configuration at the secondary site. The method then performs the storage management function at the primary site in a way that takes into account the storage configuration at the secondary site. A corresponding apparatus, system, and computer-readable medium are also disclosed and claimed herein.
