摘要： 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. 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 from the second storage system to a second storage system copy in response to the command. The second server performs the second point-in-time copy operation, in response to determining from the mirror data to create the second point-in-time copy.

摘要： An apparatus, system, and method are disclosed for activating a synchronous mirror as a primary storage volume. The apparatus system and method include directing a third storage volume to store updates sent to the third storage volume from a second storage volume onto a first storage volume in response to the first storage volume becoming operational after a failure, terminating sending updates from the second storage volume to the third storage volume in response to the first storage volume becoming substantially consistent with the third storage volume, and synchronously storing updates received by the second storage volume on the first storage volume and asynchronously storing updates received by the first storage volume on the third storage volume in response to terminating sending updates from the second storage volume to the third storage volume after the first and third storage volumes are substantially consistent.
