I've done what you are asking about many times. Just extend the logical drive in the ACU - should be an on-line event. I did this last month on a 370 G3 so I would expect it work on a 350 G3. Which array controller do you have? -Brian

I have just added a 6th drive to the server and gone into the HP ACU to extend array #2 from 3 physical drives to 4 physical drives. The array #2 was extended, however, it didn't extend the logical drive IN the array. Instead, it just shows the old logical drive (144GB), and (72GB) of free space in the array. I want to take that 72GB of free space in the array and extend the current (144GB) logical drive in that array to 216GB. Can this be done? Or do I have to just delete the 144GB logical drive in the array and recreate a new one that uses the maximum space (216GB)? I would think there's a way to extend the logical drive IN the array.
