First, create the logical volume, then create the filesystem on the new lv.
The commands are something like:
mklv -y'crmdatelv' -e'x' '-S16K' whatevervg 10
crfs -v jfs -d'crmdatelv' -m'/crmdate' -Ayes -p'rw' -tno -a frag=4096 -a
nbpi=4096 -a ag=8
mount /crmdate

NOTE: Cut&Patse of the above WILL cause problems. Find out what the
options mean first
