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： Disclosed is an article of manufacture, system, and program for determining device suspension and device blocking. Local session cache usage and residual counts are compared against limit values associated with that session, wherein the limit values comprise a device blocking count, a device blocking percent, a suspend count, and a suspend percent for the local session. If a cache in trouble condition is detected based on the comparison, the cache in trouble condition is processed to determine whether one or more volumes are to be blocked or suspended.

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 techniques for copying data. It is determined that it is time to execute a quick copy command indicating one or more control volume pairs for which a freeze indicator is set to indicate that a freeze is to occur and one or more data volume pairs for which a freeze indicator is set to indicate that a freeze is not to occur. A consistent instant virtual copy operation is performed for each of the one or more control volume pairs for which the freeze indicator is set to indicate that the freeze is to occur. An instant virtual copy operation is performed for each of the one or more data volume pairs for which the freeze indicator is set to indicate that the freeze is not to occur.

摘要： A method, device, and computer program product for performing asynchronous remote copy verification is provided. An initial track-to-track comparison between a primary and a secondary volume pair is performed. Differences between primary and secondary volume tracks are recorded as noncompare tracks. A first predetermined time is waited for. A subsequent track-to-track comparison of the noncompare tracks is performed.
