Manually Expire Media

Hi All,

Because of wrong retention period to one policy, we had low space issue.

Now I want to manually expire the media.

I know using the commands  /usr/openv/netbackup/bin/goodies/available_media     and  bpexpdate -m (media id) -d 0

My question is ,how to find and list  the all  medias which are  belongs to (for example)  billing.full policy.

Thanks in advance.
