Network Appliance products are shipped with all purchased services already licensed, so license is normally needed only to turn on new services. License is required if a new file system is created.
To turn off or disable a license, enter the code DISABLE. The license will be removed.
The following is a list of supported services:
toaster> license nfs=ABCDEFG
nfs license enabled.
nfs enabled.
toaster> license cifs=DISABLE
unlicense cifs.
cifs will be disabled upon reboot.
toaster> license nfs ABCDEFG cifs site BCDEFGH http not licensed
