It is not advisable to reduce existing lvols as you can damage data on the mountpoint, the best way is to backup your data and then blow away and recreate the lvol.
You could move all data off the mount point and then reduce it, but better to start clean...
Also, I prefer not to use SAM, it can hang and screw you up. I use command line as I showed above. That way you are in control. And you learn the commands more easily.
