Abstract
A system and method is disclosed for the automatic assignment, or reassignment, of shared storage resources to blade computers in a blade server environment. A chassis manager is implemented as a processing entity on the mid-plane of a blade server chassis to provide, independently or in conjunction with other systems and/or attached storage devices, management of shared storage resources. Management of these resources includes, but is not limited to, creation of logical units, assignment of logical units to predetermined blade server chassis slots, and deletion of logical units. Host-based software is not required to assign shared resources to a computer blade, only its presence in a predetermined slot of a blade server chassis. Logical unit numbers (LUNs) are assigned by the chassis manager based on blade server slot IDs while host-unique identifiers, such as world wide names (WWNs) are used by one or more shared storage controllers for internal LUN addressing.
