Abstract
Techniques for updating a cached version of data in a computer system upon a change of the data as stored in a shared storage system networked to the computer system are described. In accordance with such techniques, a notification from the shared storage system is received at the computer system upon attempting to access the shared storage system. The computer system then determines that the notification occurred due to an unregistering of the computer system's access to the shared storage system by a second computer system that has updated the data stored in the shared storage system. As such, the computer system re-registers its access to the shared storage system and updates the cached version of the data with the data in the shared storage system that was updated by the second computer system.
