"Non-active" tapes are unavailable for backups.  They are Full, 
Suspended, and/or Frozen.

"Active" are all the rest of your tapes that are not empty.  NetBackup 
will use them for future backups (with the same retention period).

The "are currently EXPIRED" list is probably of interest.  These are 
tapes that have no useful data on them, but will not be used for 
backups.  They are probably "frozen".  Hopefully you recorded why the 
tape is frozen (NetBackup doesn't record this, except for the case of 
the errors file (view with "less  +G  
/usr/openv/netbackup/db/media/errors")) so can deal with it appropriately.

Tapes in a non-active category eventually have their data expire 
(expirations of infinity take longer) and the tapes automatically become 
available for backups (unless frozen .. see above).

Tapes that become empty (all data expires), and are not frozen, 
disappear from this report.  Whether these tapes stay in their current 
Volume Pool or go to Scratch depends on other factors.

Hope this helps!    cheers, wayne
