Managing a shared storage system using hardware identifiers to deter data/file corruption

摘要

A method, system, and computer program product for managing a storage facility are disclosed. A potential file overlay may be detected when performing a file transfer. When a file is common to multiple systems and resides on a shared system storage volume, potential file corruption due to a data transfer request is detected and then able to be prevented. Hardware identifiers such as Universal Unique Identifiers (UUIDs) are used in managing a write of a file to shared system storage. By comparing multiple hardware identifiers, a determination is made as to whether to process the write of the file. If the hardware identifiers mismatch, the write is processed. If the hardware identifiers match, a potential file overlay is detected. Because of the potential file overlay, the write is aborted and a failure notification is returned. A successful overwrite prevention notification may also be returned.
