LT0-6 drive Block size modification in cell manager 9.08

Hi ,

Is there any way to modify block size of LT0 drives in data protector. by default it is 256kb

I want to increase it becuase Storeonce gateways are configured on 512KB and becuase of 512kb size , i cannot offload backup to tapes [MSL 6480] . ofcourse , reduce the size on storeonce gateways can be solution of this problem.

my environment- 9.08 cell manager + storeOnce 6500

thanks,

DPx
