Selecting a path comprising ports on primary and secondary clusters to use to transmit data at a primary volume to a secondary volume

A system in communication with a primary storage location and a secondary storage location, comprising:

• a plurality of primary clusters, wherein each primary cluster includes at least one port providing a path to the secondary storage location;
• and
• a program executed by at least one of the first and secondary clusters to perform operations, the operations comprising:
• receiving a request to copy data from a primary storage location to a secondary storage location;
• determining from the plurality of primary clusters an owner primary cluster for the primary storage location, wherein the primary clusters are configured to access the primary storage location;
• determining whether there is at least one port on the owner primary cluster providing an available path to the secondary storage location;
• and
• selecting one port on the owner primary cluster to use to copy the data to the secondary storage location in response to determining that there is at least one port on the owner primary cluster available to transmit to the secondary storage location.
