Issue a robot inventory Contents report to obtain the list of media in the robotic library. See whether inventory filters have been enabled in the Media Manager configuration file. Inventory filters affect the contents of the media list returned from the robotic daemon or process. Use a robot test utility or an operating system/vendor administrative interface to verify the status of media, as needed. Update the volume configuration and search for the media if it was not in the robotic library, as needed, and resubmit the request.
