1. A method for load balancing the access to an array of storage elements each element storing at least one logical device accessible to at least one host processor as a host logical volume through a storage element controller, comprising the steps ofvisually displaying in a first window portion of a host processor-controlled display monitor, a first mapping identifying for each controller host port, the logical volumes available to said port,visually displaying in a second window portion of the host processor-controlled display monitor a second mapping identifying for each controller storage port the logical devices stored in a storage element attached to said controller storage port, andhighlighting in at least the second window, for any selected host port identified in the first window, all logical devices accessible from said host port.

Abstract
The invention relates to a method for displaying, for an array of storage elements, logical devices stored on the storage elements in which each element stores at least one logical device accessible to at least one host processor through a storage element controller, in particular a disk drive controller. In accordance with the invention, a host processor operates to visually display, in a first window of the host processor-controlled display monitor, a first mapping identifying for each controller host port at least the logical volumes available at said port. The system then visually displays in a second window of the monitor a second mapping identifying, for each controller storage port, the logical devices stored on the storage element attached to the controller storage port. The system then enables the user to highlight, at least, in the second window, for any selected host port identified in the first window, all of the logical devices accessible from the host port. In other aspects, the system allows the user to highlight any of the identified elements being displayed to provide a correspondence in the first and second windows so that views from the host port side and from the storage element side can be simultaneously displayed and highlighted.
