Abstract
A processing system includes a local or local storage and a number of remote or remote storage systems that store data mirroring that maintained by the local storage system. Data that is written, changed, deleted or other wise modified by the local storage system is periodically sent to the remote storage systems via remote copy commands to update the mirroring data maintained by each. Failure of a local or a remote storage system will cause the surviving storage systems to exchange information indicative of the data maintained by each, and if differences exist, to exchange data so that the mirrored and/or mirroring data is the same.
