A problem with removing a old dbvolume

I'm running adsm under an RS6000 (Aix 4.1.3) and have a problem in that I
want to remove the database volume from ADSM.  It's 1 Gig in size and has
been used up.  I want to migrate from this logical volume to another because
I foolishly increased the size of the volume with smit to no avail, so I
want to start afresh on a new (larger) LV.

So what I did was to:
        1.  Created a 1.6 Gig logical volument called adsm_database
        2.  Added adsm_database as a dbvolume with 1596 Meg available
        3.  Attempted to delete the original 1 Gig filesystem with a
                addm> del dbvol /dev/radsm_db

I get the error
  ANR2434E DELETE DBVOLUME: Insufficient space on other database volumes to
  delete volume /dev/radsm_db.

Querying the DBvolumes (detailed) gives me:
-----
adsm> q dbv f=d
adsm> q dbv f=d

Volume Name (Copy 1): /dev/radsm_database
         Copy Status: Sync'd

Yet still I cannot delete the old volume and migrate the data from one
Yet still I cannot delete the old volume and migrate the data from one
dbvolume to the other.

Is there any known fix to this?
