You could do something like this, which assumes TLD libraries and works 
with Netbackup V4.5 on Tru64:

#!/bin/ksh

# Show the number of free tapes, and the total number of tapes in each 
media
# pool by library

for POOL in `vmpool -listall -b | tail +3 | cut -d " " -f 1` ; do
   HEADER=0
   for LIBNAM in `tpconfig -d | grep 'TLD(' | awk '{print $1}' | sort -u` 
; do
      LIB=${LIBNAM#TLD\(} ; LIB=${LIB%\)}
      TOTL=`vmquery -w -pn $POOL | awk "\\$8 == \"${LIB}\" { print \\$0 }" 
| wc -l`
      if [[ $TOTL -eq 0 ]] ; then continue ; fi
      FREE=`vmquery -w -pn $POOL | awk "\\$20==\"00/00/0000\" && \\$8 == 
\"${LIB}\" { print \\$0 }" | wc -l`
      if [[ $HEADER -eq 0 ]] ; then echo $POOL ; HEADER=1 ; fi
      echo "   lib$LIB: $FREE / $TOTL"
   done
   TOTL=`vmquery -w -pn $POOL | awk "\\$7 == \"NONE\" { print \\$0 }" | wc 
-l`
   if [[ $TOTL -ne 0 ]] ; then
      if [[ $HEADER -eq 0 ]] ; then echo $POOL ; HEADER=1 ; fi
      FREE=`vmquery -w -pn $POOL | awk "\\$20==\"00/00/0000\" && \\$7 == 
\"NONE\" { print \\$0 }" | wc -l`
      echo "    s/a: $FREE / $TOTL"
   fi
done
