1. A method comprising:
identifying that a target storage system is replicating a source volume of a source storage system, wherein a first host computing device that issues input and output (“I/O”) operations to the source volume is mapped to the source volume on the source storage system;
providing, on the target storage system, based on a host-to-volume mapping that maps the first host computing device to the source volume, configuration information for connecting the target storage system to a second host computing device that can issue I/O operations to a replica volume at the target storage system; and
implementing, in response to a triggering event that includes a failure at the source storage system, another host-to-volume mapping that maps the second host computing device to the replica volume on the target storage system by using the configuration information.
