Abstract: Provided is a method 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.

Abstract: Provided are a system and article of manufacture for mirroring data. A mirror policy indicating volumes in a first storage system is processed to mirror to volumes in a second storage system and volumes in the second storage system to mirror to volumes in a third storage system. The third storage system is at a first geographical location remote with respect to a second geographical location including the first and second storage systems. A command is transmitted to cause the copying of updates to the volumes in the first storage system to corresponding volumes in the second storage system indicated in the mirror policy. Upon an occurrence of an event, the causing the suspension of the copying of updates to the volumes in the first storage system indicated in the mirroring policy to the volumes in the second storage system.

Abstract: Provided are a computer program product, system, and method for maintaining mirror and storage system copies of volumes at multiple remote sites. A first server maintains a mirror copy relationship in a computer readable storage medium between a first storage system at a first site and a second storage system at a second site to mirror data at the first storage system to the second storage system, wherein the first and second sites connect over a network. 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, wherein the point-in-time copy operation is completed upon creating a data structure indicating data for the first storage system copy as located at the first storage or the first storage system copy. The first server transmits a command to a second server to create a point-in-time copy of the second storage system.

Abstract: Providing extended or end-to-end data integrity through layers of a system.

Abstract: Provided are a method, system, and article of manufacture wherein a command is received for writing data to a first storage location. A determination is made that previously written data is stored in the first storage location. The previously written data is copied to a second storage location, in response to determining that the previously written data is stored in the first storage location. The data is written to the first storage location, in response to copying the previously written data to the second storage location.

Abstract: Provided are a method, system and article of manufacture, wherein a request to access data is received from a requestor. A determination is made as to whether the requestor is authorized to access the data. In response to determining that the requestor is authorized to access the data, a determination is made as to whether the data is encrypted. An encryption key is requested from the requester, in response to determining that the data is not encrypted.

Abstract: Provided are a method, system and program from for 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.

Abstract: A data storage system writes data supplied from a host to data storage in accordance with write I/O of an owning application. A workload manager directs the processing of the supplied data in accordance with the write I/O of the owning application, provides service workload identification describing the write I/O, a storage subsystem control adds the service workload identification to record set information for the data, and a journal management system stores the record set information in a journal. The journaled information, for example, may be employed for performing forensic analysis of data corruption events or to perform security audits, etc.

Abstract: 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.

Abstract: Provided are a method, system, and article of manufacture, wherein a primary control unit sends a selected time to a plurality of secondary control units.
