Can you state what is going on! Migration has nothing to do with copy pools. Each backup object can have only one primary sequential pool associated with it unless the cache on disk is used, but it still gets migrated. These objects have additional objects associated that are the copy storage pool objects.
This is an example of the show bfo (Bit File Object) for a backups table entry. You will notice this is what connects the backups table to the contents table. **Sub-bitfile 0.203027760 is stored in the following aggregate(s) Super-bitfile: 0.203027760, Offset: 0.0, Length 0.646 **Archival Bitfile Entry Bitfile Type: PRIMARY Storage Format: 9 Bitfile Size: 0.702823 Number of Segments: 1 Storage Pool ID: 10 Volume ID: 8513 Volume Name: 421705 **Archival Bitfile Entry Bitfile Type: COPY Storage Format: 9 Bitfile Size: 0.702823 Number of Segments: 1 Storage Pool ID: -3 Volume ID: 8493 Volume Name: 400586 **Archival Bitfile Entry Bitfile Type: COPY Storage Format: 9 Bitfile Size: 0.702823 Number of Segments: 1 Storage Pool ID: -13 Volume ID: 8538 Volume Name: 423547 Typically, if collocation is set to NO migration will fill up a cartridge unless you are specifying many more than process maxpr=x. If you have collocation turned on. All bets are off. Migration will make every attempt to collocate the data for a node/filespace. This usually means at least one tape per. Paul D.

Is the fact that a copy pool cartridge is also sent offsite have anything to do with my theory.If anyone has any thoughts on this i would appreciate it if you could please set them down on paper.
