We are running TSM 5.3.0.0 ser ver on AIX 5.3.0 with 10 LTO drives in a 3584 
library. We have 10 lto storage pools ( sequential) we always have two  prime 
stg tape pools in the library and we rotate 3 offsite tape pools on weekly 
basis. We are always very low on the Scratch tape we run reclamation using TSM 
admin. schedule. Would like to optimize to take full advantage of 10 drives and 
also if TSMers would like to share any  BKM ( Best known methods) for 
reclamation process implementation. Each pool is roughly 100 tapes.

Thanks
Ashok
