Abstract: A method, apparatus, and computer program product for managing permissions for processing input/output (I/O) operations in a storage system is disclosed that includes a plurality of storage system controllers and a plurality of storage devices. The method comprises determining that a permission associated with a storage system controller for issuing I/O operations to the storage devices should be invalidated and, in response to the determination, modifying at least one I/O capability of the storage system controller.
