The initial configuration appears to be inconsistent and a lot of changes were 
made by the command-line tools.  To isolate my issues, I believe a rebuild is 
the best approach.  I can do a clean install and setup a few clients then 
approach EMC if I am still having issues.  One of the more recent issues 
involved the LUN assignment for the tape drives.  They appeared to be 
dynamically generated... I have not sat down and looked into this issue.  EMC 
mentioned that I need to make the LUN mappings static.  

The old tapes are a complete mess, some have been selected for recycle (done 
prior to my arrival at this position), and others in the set are missing.  The 
media pools are not configured properly.  Looks like some sort of auto media 
management is taking place and tapes are being reassigned.  So rather than mess 
with these tapes, I would like to remove them all together... and replace them 
with the spares I have available.  However, accessing the tapes in the future 
may be required... so I wanted to know how easy/difficult it would be to do 
this and the procedure to take these tapes offline.  Is there something I 
should do before I wipe out the current install?   The client names will change 
when I reconfigure... something that I have recently done and experienced 
problems with.  Does the DR guide outline a DR practice run?  I have not looked 
at this resource yet.  I am in the early stages of planning at this point.
