CONTROLLER-MEDIATED VOLUME TRANSFORMATION IN A SHARED-RESOURCE ENVIRONMENT

摘要

A computer program product is provided for storage controller-mediated volume transformation in a shared-resource environment. The computer program product comprises a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a computer to cause the computer to receive, from an initiating host system, a command to send a notification to other host systems connected to a shared volume. Additionally, the programs instructions are executable by the computer to cause the computer to broadcast an interrupt to the other host systems connected to the shared volume, and receive responses from the other host systems connected to the shared volume. Moreover, the programs instructions are executable by the computer to cause the computer to notify the initiating host system of the responses received from the other host systems connected to the shared volume.
