hi, ADSM'ers

I just installed a server ADSM on a AS400 with a library Magstar 3570.
The version OS400 is V4R3
The version ADSM is 3.1.5
The 3570 runs OK, but it cannot to fill the cartridges more 5 Go.
The config of the devclass is: device type=3570 , format=drive.
Could you help me to fill the cardridge whith 10 or 15 Go of datas.

Thanks you.
