Abstract
The present invention is directed to a method and software for managing the host-to-volume mappings of a SAN storage system. The host-to-volume mappings of the SAN storage system are represented in mapping configuration components. The active mapping configuration component represents the current host-to-volume mapping for the SAN storage system. Only one mapping configuration component is active at a time. The host-to-volume mappings of a SAN storage system are changed by deactivating the active mapping configuration component and activating an inactive mapping configuration component that represents a different mapping configuration, effecting a repartition, repurpose, disaster recovery, or other business activity. This can be a scheduled task or performed in an on-demand manner. The mapping configuration components are managed and controlled through the management component of the SAN storage system.
