Abstract:
A simulated stretched volume may be configured from multiple volumes of a single data storage system. The volumes may be assigned unique identifiers. The volumes may be exposed to a host over paths from the single data storage system as the same volume having the same unique identifier. The single data storage system may include sets of target ports with each set simulating paths to a different data storage system. A management command may be received that is directed to the simulated stretched volume having the unique identifier. The management command may be received on a path from the host to a target port of the single data storage system. Servicing the management command may include the single data storage system simulating either the local or remote system depending on the set of target ports including the target port.
