In our DR procedure we have included only the last 8 days of our COPY_POOL 
volumes from DRMEDIA table, that need to be sent to DR Site. Our backup size is 
almost 2Tb on a daily basis and we do full backups weekly and incremental on a 
daily basis to LTO1.
Using this method we can control the number of volumes that need to be sent to 
our DR center, and we can reduce operations during recover, otherwise we need 
to load required volumes into the library each time TSM require. 

We send prepare file and "priority volumes" (from drmedia table) to our DR site 
and to our offsite safe. You'll not need to change anything in you prepare 
file, DR plan and DR tests. 
The result in a DR Test scenario should be the same as your DR Plan.

You shouldn't create DR scenario tests that are different from your DR Plan 
otherwise things might not work. 

The major advantage is to test DR with COPY_POOL, but you only need to transfer 
part of your COPY_POOL and not all COPY_POOL volumes. Of course for security 
purposes....
