Origianlly had 2 3590-1 tape drives in 3494 tape subsystem, all was fine
We added 2 stanadalone 3590 tape drives . The origianal and new drives
are both UNIT=3590-1

Both my primary storage and copy storage pools use a DEVCLASS with UNIT=3590-1

When I copy a primary storage pool to a copy storage pool I get a Z/OS message 
IKJ56241I

Since both the tape subsystem and standalone 3590s are both 3590-1
how can I force TSM to use the tape subsystem tape units
