how to create a striped with replicated volume

Hi,

I know how to create a pure striped  volume, but it's not security for this
kind of volume.
How can I create a striped volume with replicated like RAID1+0?
By the way, Can we change the stripe count later after created the striped
volume?


Thanks in advance!
