Abstract: A distributed storage management program manages a network comprising multiple data storage devices attached to multiple host computer systems. The management program includes a separate agent in each host, and a central manager. The agents gather data and communicate with the manager across a communications path which is independent of the storage network. The manager collates the data from different agents to produce a coherent view of the network. Preferably, each local agent actively builds an internal topological view of the network as seen by its host and collects data such as error events, which it stores in internal data structures. The manager is able to resolve gaps in the information of each agent from information provided by other agents. Preferably, the manager represents the network as a collection of objects of different classes in an object-oriented class library. This collection is graphically displayed in a logical and understandable manner to a user on a display device.

Abstract: A portable tool box having an open-top, box-like housing containing removable slats with apertures for holding tools in an upright position and a drawer slidably engaged within a drawer aperture in one wall of the housing. The drawer outer wall has an outwardly projecting shelf and a lip extending above the shelf. A cover disposed over the housing has an endwall which covers the lip for retaining the drawer in the housing. Preferably, the shelf extends around the perimeter of the housing for supporting bottom edge of one or more of the walls of the cover. The tool box cover is sturdy enough to be used as a stool.
