AUTOMATED MIGRATION TO A NEW COPY SERVICES TARGET STORAGE SYSTEM TO MANAGE MULTIPLE RELATIONSHIPS SIMULTANEOUSLY WHILE MAINTAINING DISASTER RECOVERY CONSISTENCY |
| 摘要 |
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. |

1. A method, comprising:
receiving instruction to change from an original target storage subsystem in a disaster recovery configuration-to a new target storage subsystem; creating second copy services relationships 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; and terminating existing first copy services relationships between the source storage subsystem and the original target storage subsystem after all of the second copy services relationships are full duplex. |
