filer> sis stop /vol/vol1
Operation is currently idle: /vol/vol1

Next, disable A-SIS on the volume:

filer> sis off /vol/vol1
SIS for "/vol/vol1" is disabled.

Finally, make the volume “fat” again:

filer> priv set advanced
Warning: These advanced commands are potentially dangerous; use
them only when directed to do so by Network Appliance
personnel.
filer*> sis undo /vol/vol1
filer*> sis status /vol/vol1
Path State Status Progress
/vol/vol1 Disabled Undoing 6810 MB Processed
filer*> priv set
filer>

Be sure to do the math to make sure you will have enough space in the fat volume once deduplication is undone. See my Practical Limits of NetApp Deduplication post elsewhere for more on this.
