Abstract: A method and system for constructing and analyzing an access path event history in a network is provided. Inconsistencies in the physical and logical access paths when making changes in the network are detected and analyzed. Component events associated with network appliances are recorded and an event sequence is constructed. Root causes for the inconsistencies are identified and the access paths are repaired in conformance with the network access path policy. The method and systems can be applied to networks in general, and more particularly to storage area networks (SAN).
Abstract: A method and system for validating logical access path in a storage area network is provided. It supports definition of a SAN access path policy that represent which application to data LUN logical access paths should not exist, which should exist, and what should be the end-to-end attributes of each. It performs the SAN-customized graph-based validation algorithm based on information it collects automatically from devices distributed across the SAN using a variety of non-intrusive mechanisms. It enables to identify violations of actual logical access paths relative to the required access paths as determined by the policy. It enables notification about violations, with all their relevant context information, to the appropriate target recipient using a variety of means.
