Abstract: Methods, systems, and computer program products for providing deferred replication of recovery information at site switchover are disclosed. A computer-implemented method may include receiving a first copy of logged data for storage volumes of a disaster recovery (DR) partner at a remote site from the DR partner, receiving a request to perform a site switchover from the remote site to the local site, receiving a second copy of logged data for the storage volumes from a local high availability (HA) partner in response to the switchover, and recovering the storage volumes locally by applying one or more of the copies of logged data to corresponding mirrored storage volumes at the local site.

Abstract: A system and method for avoiding object identifier collisions in a cluster environment is provided. Upon creation of the cluster, volume location databases negotiate ranges for data set identifiers (DSIDs) between a first site and a second site of the cluster. Any pre-existing objects are remapped into an object identifier range associated with the particular site hosting the object.

Abstract: Techniques for recovering from a failure at a disaster recovery site are disclosed. An example method includes receiving an indication to shift control of a set of volumes of a plurality of volumes. The set of volumes is originally owned by a second storage node. The first storage node is a disaster recovery partner of the second storage node. The method includes shifting control of the set of volumes. The method further includes during the shifting, changing a status of a flag corresponding to a progress of the shifting. The method also includes during a reboot of the first storage node, determining the status of the flag and determining, based on the status of the flag, whether to mount the set of volumes during reboot at the first storage node.
