Hi,
Better way is to reduce this disk in the vg.
After that you could remove it by
saconfig /dev/ciss2 -D 0
check the doc

Hope it helps

IMHO you can only delete the existing RAID (offline) - you will loose all the data - and create 2 RAID 0 logical drives.

Hope this helps!

You can also try a RAID migration - make sure you have a good backup!

# saconfig /dev/cissX -M -R

Hope this helps!
