An apparatus and method are disclosed to manage one or more reserved volume serial numbers in a virtual library grid. The method supplies a virtual library grid comprising one or more virtual library clusters, wherein each of said one or more virtual library clusters comprises a management interface node, at least one virtualization node, at least one management node, at least one library manager node, at least one direct access storage device, one or more information storage media, and at least one data storage device to read information from and to write information to the one or more information storage media. The method then reserves in each of the one or more virtual library system clusters one or more volume serial numbers, and establishes a time out period. The method then determines if the time out period has expired. If the time out period has expired, the method unreserves in each of the one or more virtual library clusters the one or more volume serial numbers.
