Deleted device class and storage pool wth l. 200+ volumes associated with it

Apparently in Sept 2012 I deleted a device class and recently noticed that there are still 269 volumes associated with it. That would explain my ever low Scratch count.

When I run a query content I see data on the volumes.

If I run q occ "node" * I can see existing storage pools Local (ltopool) and Remote (Copy_Off). So in theory there should be two copies of the data and I shouldn't need the other tapes. Does that sound accurate?

Example output from q occ
tsm: TSMA>q occ tpc02 *

Is there any way to see the dates of the data on those volumes? Would I need to recreate the deleted device class and storage pool?
Thanks,
