VTL(Data domain issue) with Backup exec 2010R3, backup job in queued

Hi,

I am using BE2010 R3 with VTL and one of my backup job in queued as all medias of target partition are full. i exported some media and imported another media to the same slot but after scanning it is not coming to running state and not able to perform any other operation like inventoy etc. goes to scheduled job with error ideal device as existing drive is busy with queued job. around 2.3 tb job is completed

Thanks....
