We have one AS/400 and already had a 3494 library with 3590 drives for TSM.  
Since BRMS or Robot Save would have been required with TSM, we attached the 
AS/400 directly to one of the dual ported 3590 drives and share the library.  
At night the AS/400 uses the drive with BRMS.  The drive is online to TSM 
during the day for storage pool copy activity.

This setup also provides better performance than tramitting the AS/400 data 
over a network to TSM.
