Abstract
In one aspect, a method includes receiving notification that a volume in a plurality of volumes has failed, determining a smallest consistency group with a replication trigger point designation using a hierarchical volume tree that includes the failed volume, stopping replication of volumes in a first consistency group if it is determined that the first consistency group is the smallest consistency group with a replication trigger point that includes the failed volume and stopping replication of the plurality of volumes if it is not determined which is the smallest consistency group with a replication trigger point that includes the failed volume.
