Abstract
Method and system is provided for performing a failover operation during which a second storage system takes over the management of a storage volume managed by a first storage system. The first storage system may also manage a plurality of replicated copies of the storage volume and maintain metadata for storing information regarding the replicated copies. The failover operation is completed without having the second storage system read all the metadata.
