ABSTRACT:
Systems, methods, apparatus and software can implement a SAN monitoring scheme for determining changes in SAN topology, such as device failure and state changes. These changes are recorded in a SAN topology data structure. Information in the SAN topology data structure is used, for example, to identify a suspect path or set of paths, and to make decisions about communications pathways used by a multipath device driver.
