FLASHCOPY RESERVATION FOR FLASHCOPY ONTO A SYNCHRONOUSLY-MIRRORED SOURCE |
摘要 |
A method, system and computer-usable medium are disclosed for improved point-in-time copying of data within an asynchronous data mirroring environment. A first establish for a first point-in-time copying process is generated, followed by submission of a request to initiate an asynchronous data mirroring process associated with the first point-in-time copying process. In response, a point-in-time establish reservation is generated for a second point-in-time copying process. If it is not possible to successfully perform the second point-in-time copying process, then the point-in-time establish reservation is cancelled and the first point-in-time copy establish is failed. Otherwise, the point-in-time establish reservation is then used to generate an establish for the second point-in-time copying process, which is then initiated. |

1. A computer-implemented method for data mirroring, comprising:
receiving a request to initiate an asynchronous data mirroring operation associated with a first point-in-time copying process; processing a first set of establish data to generate a point-in-time establish reservation, the first set of establish data associated with the first point-in-time copying process establish; using the point-in-time establish reservation to generate a second set of establish data if the second point-in-time copying process can be performed; and using the second set of establish data to initiate a second point-in-time copying process. |
