Sachin,

Try this:

"Label Libvol library_name search=yes labels=prompt checkin=scratch"

It will label all the volumes that aren't checked in, and then check in
those newly labeled volumes...

search=bulk -> looks for a tape only in the priority slot
search=yes  -> looks for tapes in all slots except the priority slot

checkin=scratch -> after labeled the tapes are checked in as scratch
checkin=private -> after labeled the tapes are checked in as private

Good Luck
