Hi, 
I am using TSM 4.2.1.9 on AIX 4.3.3 with 3583 Library (3 Drives on it) 

I have a disk pool about 3GB. All my schedules starts at 7pm but some 
clients' files are over 1.8GB on a low bandwitdth. These clients 
try to write next stg pool (to a tape pool) directly although their 
destination pool is my disk pool. I came to a conclusion that due 
to not enough space on disk pool during backup of many clients 
some of them are trying to write tape pool even though tape drives are very 
slow. 

Do you have any idea to prevent clients to write my tape pools 
directly (I use migration and at %60 the disk pool migrates to tape pool). 

I want all clients to write to disk pool and migrate them according 
to above condition whatever the size or bandwitdh of data. 

Thank you in advance 
Burak
