Abstract:
1. A computer program embodied on a computer readable medium, comprising: program instructions for gathering information of one or more storage area network (SAN) components in a discovery process from one or more sources for a storage infrastructure manager (SIM); program instructions for storing the information in a database; and program instructions for analyzing the information from the discovery process to infer which of the one or more SAN components are currently detectable to the SIM, where each of the one or more sources of the information are each classified as either only an authoritative source or only a nonauthoritative source and the information from any authoritative source is prioritized over the information from any nonauthoritative source and the nonauthoritative sources can define one of the one or more SAN components in the discovery process as missing only if all of the nonauthoritative sources report the one as missing in their most recent scan and any authoritative source can define the one as missing; wherein the SIM accepts a report from an authoritative source that a SAN component is missing without waiting for reports from additional sources.
