ABSTRACT:
A method, system, and program product for controlling multi-node access to a disk storage system. In accordance with the method of the present invention, an active access authorization is set for a first node. The active access authorization enables read and write access by the first node to user and meta data within the disk storage system. A passive access authorization is set for a second node. The passive access authorization enables read-only access by the second node to logical volume management meta data within the disk storage system.
