Symmetrix space reclaim confusion

First off, I'd like to thank the guys who helped me with my previous issues/questions! You guys are great!

My problem now is that I'm trying to reclaim space on a DMX 1000 - running 5671.75.75 and SE 7.01.

I have gone through the process of removing old split BCVs, supposedly recovering 2+TB of space (2416836 MB). However, it looks like I've only cleared 1553675 MB, leaving 863161 MB out there somewhere - unless my math is wrong.

Before:

               Total        Configured   Unconfigured Hypers Format

Total         ------------ ------------ ------------ ------ ----------
                   8808307      7160108      1635625    650 FBA
                   1118515         6521       382456    400 CKD-3390

    Device Config      FBA    CKD   AS400  CELERRA
  -----------------   -----  -----  -----  -------
  2-Way Mir             147    N/A    N/A    N/A
  RDF1+Mir               36    N/A    N/A    N/A
  RDF1+R-S              N/A    300    N/A    N/A
  RDF2+Mir               70    N/A    N/A    N/A
  BCV                   140    N/A    N/A    N/A
  DRV                     4    N/A    N/A    N/A

After deleting BCV devs:

Total         ------------ ------------ ------------ ------ ----------
                   9926822      6476104       288835   1010 FBA

     Device Config      FBA   CKD3390  CKD3380  AS400  CELERRA
  -----------------   -----  -------  -------  -----  -------
  2-Way Mir             197      N/A      N/A    N/A    N/A
  RDF1+Mir               36      N/A      N/A    N/A    N/A
  RDF1+R-S              N/A      300      N/A    N/A    N/A
  RDF2+Mir               70      N/A      N/A    N/A    N/A
  DRV                     4      N/A      N/A    N/A    N/A

In the interim, I created 50 additional 17GB devices totaling 863150 MB and run a bin file that removed the EA controllers, as the CKD devices are no longer needed. Unfortunately, I'm having problems removing the CKD devices as they are static RDF. My goal is to reclaim 2TB of space to create new FBA metas. Am I missing something here? Thanks!
