You placed this thread in LVM and VxVM - that's good.

Just create a new LVOL without a filesystem - that's it.

IMHO you should create 2 LVOLs, 4GB each.

raw device is nothing but a LVOL without file system.

you can create LVOL with size and slice it is you have available space in that VG.

Instead of saying slicing...you say i need two small logical volumes here..

Sure, you can create two LVs here.

RAW means no file system structure creation on LV.

so as long as you dont run newfs for creating File system on newly created LVs all will remain raw devices....

I hope this will clear query here...:-)
