I'm new to ADSM and pehaps someone can help me understand a strange problem(?). 
  I am running ADSM v3.1 level 1.5 on AIX 4.2.1.  I have an ADIC Scalar 224 
(with two DLT-7000 drives) attached to the system.  I have defined the library 
for ADSM.

The tape library can hold 24-tapes and each tape is 30GB.  This gives me a 
total of 720GB.  Unfortunately, when I query the storage pool the value of 
Estimated Capacity is 18.108TB which is incorrect!  And, to further muddy the 
waters, when I query my volumes (which ADSM created dynamically when it was 
doing a migration) under my tape storage pool, each of the volumes are 720GB.  
Can someone either help me fix this or point me in the right direction?  Below 
is the output of the query commands.
