20090144344 | APPARATUS, SYSTEM, AND METHOD FOR REPLICATION OF DATA MANAGEMENT INFORMATION - An apparatus, system, and method are disclosed for replication of data management information. A base replication module replicates a base table on an active server to a first and second standby server. The base table comprises configuration parameters for storage devices, logical volumes, physical interconnections, logical interconnections, and logical subsystems of a storage system, and the like. A session replication module replicates first sessions from a session table stored on the active server to the first standby server and second sessions to the second standby server. The session table stores a plurality of sessions. Each session comprises a plurality of copy sets. The active server manages the sessions using the base table and the session table, and the first and second standby servers do not manage the sessions. A transfer module transfers management of the first sessions to the first standby server. | 06-04-2009 |
20090177850 | APPARATUS, SYSTEM, AND METHOD FOR A READ-BEFORE-WRITE STORAGE CONTROLLER INSTRUCTION - An apparatus, system, and method are disclosed for a read-before-write storage controller instruction. A sequencer receives an atomic read-before-write instruction comprising new data, a target address for the new data, and an undo log address. An I/O unit reads old data from the target address, writes the old data and the target address to the undo log address, and writes the new data to the target address as directed by the sequencer. | 07-09-2009 |
20090319945 | INTERFACE FOR USING DESIRED STATE COMMANDS ON A COPY SERVICES MANGEMENT SYSTEM - A data replication management interface is provided for selecting a state for replicating data from one site to another site. A pictorial representation of and/or a command line for multiple states is displayed. A pictorial representation of a current state is displayed. Each one of the multiple states respectively corresponds to multiple steps to accomplish each one of the multiple states. The multiple states are configured to be individually selected. An individual selection of one of the multiple states causes the multiple steps for the individual selection to be accomplished. The individual selection of one of the multiple states is selected by a user without requiring the user to choose any of the multiple steps to accomplish the individual selection. | 12-24-2009 |
20130036326 | ACQUIRING A STORAGE SYSTEM INTO COPY SERVICES MANAGEMENT SOFTWARE - In one embodiment, a computer program product includes a computer readable storage medium having computer readable program code embodied therewith, configured for: validating a replication of copy services between a first storage system and a second storage system, removing a plurality of existing copy relationships between the first storage system and a failed storage system, creating a plurality of copy relationships between the first storage system and the second storage system, and synchronizing a plurality of data between the first storage system and the second storage system. In more embodiments, a system includes logic for performing the above functionality, and a method includes steps for performing the above functionality. | 02-07-2013 |
20140059003 | AUTOMATED MIGRATION TO A NEW TARGET VOLUME VIA MERGED BITMAPS TO MAINTAIN CONSISTENCY - Aspects of the present invention relate to data migration and/or disaster recovery. One embodiment enables merging of bitmaps to allow for automation of the process of switching to a different target volume on the same storage subsystem without major interruption of data recovery capability and limited interruption of host I/O to the source volumes during the migration. In one approach, the migration of data onto a new target volume within the same storage subsystem as the original target volume is automated, without requiring the user to manually create or remove any new copy relationships | 02-27-2014 |
20140059009 | AUTOMATED MIGRATION TO A NEW COPY SERVICES TARGET STORAGE SYSTEM TO MANAGE MULTIPLE RELATIONSHIPS SIMULTANEOUSLY WHILE MAINTAINING DISASTER RECOVERY CONSISTENCY - In one embodiment, a method for switching a storage subsystem in a disaster recovery configuration includes receiving instruction to change from an original target storage subsystem in a disaster recovery configuration including: a source storage subsystem including one or more source volumes from which data is copied in first copy services relationships, the one or more source volumes being accessible to an application, and the original target storage subsystem including one or more original target volumes to which data is copied in the first copy services relationships; selecting a new target storage subsystem to replace the original target storage subsystem, creating second copy services relationships between one or more new target volumes on the new target storage subsystem and the one or more source volumes on the source storage subsystem using multi-target functionality, and terminating the first copy services relationships after all the second copy services relationships are full duplex. | 02-27-2014 |
20140059307 | AUTOMATED MIGRATION TO A NEW COPY SERVICES TARGET STORAGE SYSTEM TO MANAGE MULTIPLE RELATIONSHIPS SIMULTANEOUSLY WHILE MAINTAINING DISASTER RECOVERY CONSISTENCY - A system according to one embodiment, includes one or more source volumes on a source storage subsystem from which data is copied in first copy services relationships, the one or more source volumes being accessible to an application; one or more original target volumes on an original target storage subsystem to which data is copied in the first copy services relationships; logic configured for selecting a new target storage subsystem to replace the original target storage subsystem; logic configured for creating second copy services relationships between one or more new target volumes on the new target storage subsystem and the one or more source volumes on the source storage subsystem using multi-target functionality; and logic configured for terminating the first copy services relationships after all of the second copy services relationships are full duplex. | 02-27-2014 |
20140059308 | AUTOMATED MIGRATION TO A NEW TARGET VOLUME VIA MERGED BITMAPS TO MAINTAIN CONSISTENCY - Aspects of the present invention relate to data migration and/or disaster recovery. One embodiment enables merging of bitmaps to allow for automation of the process of switching to a different target volume on the same storage subsystem without major interruption of data recovery capability and limited interruption of host I/O to the source volumes during the migration.

20150052324 | AUTOMATED MIGRATION TO A NEW COPY SERVICES TARGET STORAGE SYSTEM TO MANAGE MULTIPLE RELATIONSHIPS SIMULTANEOUSLY WHILE MAINTAINING DISASTER RECOVERY CONSISTENCY - A method according to one embodiment includes receiving instruction to change from an original target storage subsystem in a disaster recovery configuration-to a new target storage subsystem. Second copy services relationships are created between one or more new target volumes on the new target storage subsystem and one or more source volumes on a source storage subsystem using multi-target functionality. Existing first copy services relationships between the source storage subsystem and the original target storage subsystem are terminated after all of the second copy services relationships are full duplex. | 02-19-2015 |
20150088821 | DATA MIGRATION USING MULTI-STORAGE VOLUME SWAP - In one embodiment of the present description, data is migrated to a replacement source storage unit of a storage subsystem while being mirrored from the original source storage unit of a storage subsystem to an original target storage unit of a storage subsystem, and the original source storage unit and the replacement storage unit are swapped in a multi-storage volume swap to write updates to the replacement source storage unit instead of the original source storage unit, in input/output operations issued by at least one host. Further, data stored in the replacement source storage unit, is mirrored from the replacement source storage unit to the original target unit. Other aspects are described. | 03-26-2015 |
