Systems and methods for identifying and correcting storage system inefficiencies are provided. One method includes discovering Logical Unit Number (LUN) information from a network storage system node, the LUN information associated with a first LUN and including an initiator group (IGroup) associated with the first LUN; discovering node information. The node information includes logical interface (LIF) status information. The method includes determining whether LUN access information also comprises a port set associated with the IGroup; combining the LIF status information and the initiator access list of the IGroup to test accessibility of the first LUN, when a port set is not associated with the at least one IGroup; and combining the LIF status information, the initiator access list of the IGroup, and the LIF access list of the port set to test the accessibility of the first LUN, when there is a port set associated with the IGroup.
