Abstract

A method, system, and computer program product for providing enhanced management features for a SAN with scalable hosts. Partitioned hosts (or ‘scalable’ hosts) are managed by extending SAN manager host-centric logical views to show (1) the host partition hierarchy and (2) the storage resource ownership for a SAN-attached scalable host. The extended host-centric view includes the host system, hosting OSes (if applicable), hosted OSes for each hosting OS (or the host system), OS volumes for each hosted OS, and logical mapping of each OS volume to the SAN storage resource (logical unit). The SAN manager is extended to also show how hosting (trusted) partitions, blades, and/or cluster members physically connect into a SAN. Users are able to toggle between a host centric view and a physical topology view by selection of items within the interface.
