command to make a media a primary copy

Hi Champs,

I have my copy 2 images on a single tape.My primary tape is missing.

Is there any command by which I can make this media a primary copy?I have all images on this single media which are copy 2.

Set primary copy is the option.and ALT_RESTORE_COPY_NUMBER.

But I need the command by which all images on this media becomes primary or this media becomes primary copy.
