Abstract
A request to access a virtual tape volume is identified and a lock status is maintained for the virtual tape volume. The lock status includes a shared status and an exclusive lock status. In shared status, it is determined whether the request includes a request for write access to the virtual tape volume. Concurrent access to the virtual tape volume can be allowed by two or more applications during the shared status based at least in part on whether the applications request for write access to the virtual tape volume.
