Uploading iSO images to ISO domain sucessfully, but no see it in RHEVM GUI

Hi all,
As my title, I have ISO domain (name: ISO), I have upload ISO files to /tmp/ISO, I have used: engine-iso-uploader --iso-domain=ISO upload iso_files, and upload successfully, but I don't see them in RHEVM GUI. Please show me how to check (by commandline) which ISO images have uploaded and how to do RHEVM show them!
thanks,
