System, Method and Computer Program Product for Partially Synchronous and Partially Asynchronous Mounts/Unmounts in a Media Library

Systems, methods and computer program products for determining completion of commands in a library system and providing an indication of the completion to a component of the media library system so that other commands which are dependent upon the completion can be efficiently issued and executed. In one embodiment, a tape is mounted in a drive of the library and a filesystem mount command is issued to initiate a filesystem mount operation. Diagnostic information generated by the operating system for this operation is communicated to the media library management application. When the filesystem mount process is completed, a corresponding diagnostic message is communicated to the media library management application. Until this message is received by the media library management application, commands that are dependent upon the completion of the filesystem mount process are inhibited, and afterward these dependent commands are allowed to be issued.
