1. A method (600) for creating redundant logical connections, comprising:

  • providing (602) a physical connection topology and a logical connection topology between a host (302) and a logical unit hosted on a storage array (308), said physical connection topology and said logical connection topology comprising all network fabrics to which both said host (302) and said storage array (308) belong;

    determining (604) at least one single point of failure is located between said host (302) and said logical unit within a particular network fabric;

    attempting (606) to create a fully redundant logical connection between said host (302) and said logical unit within said particular network fabric;

    if a fully redundant logical connection is not possible in said particular network fabric, attempting (608) to create a fully redundant logical connection between said host (302) and said logical unit using an alternate of said network fabrics; and

    if a fully redundant logical connection is not possible in any alternate network fabric in said topologies, attempting (610) to create a partially redundant logical connection between said host (302) and said logical unit within said particular network fabric.
