Abstract
A machine implemented process and system is provided. The process determines if any right granted to an entity for performing an I/O operation associated with a data container stored at a first storage volume is to be revoked. The right itself may be cached at the first storage volume and resident at a second storage volume. A recall message is sent to the node that manages the second storage volume. Any pending I/O operation is completed, after the message is sent and before the right is revoked. Thereafter, the right is revoked and the cached copies of the right are invalidated.
