Command to show Volume Group for one or all MediaIDs

Hello everyone,

I need a command that shows the volume group for one or all MediaIDs (tapes).  I tried bpmedialist but that doesn't show me the volumne group as shown here:

bpmedialist -m APA164 -U 

Server Host = inf-srv17

 id     rl  images   allocated        last updated      density  kbytes restores
           vimages   expiration       last read         <------- STATUS ------->
--------------------------------------------------------------------------------
APA164   0    274   11/28/2012 17:53  11/29/2012 07:15   hcart   435026944     0
              274   12/20/2012 05:35        N/A         SUSPENDED

I'm running NetBackup 7.1.  Any recommendations?
