If you have snapdrive installed, then you can use the snapdrive CLI to create the snap from the host.
The other options are rsh or ssh to the filer to create the snapshot.
Cheers

Subject: RE: Automatically delete snapshots based on number and not space availability
Everyone is assuming that the NetApp will be taking the snapshots, which
is incorrect. I must do the snapshots from the host side in order to
quiesce the filesystem (actually, the database). My databases run on
LUNs over FCP. I do not want to try and coordinate the databases on the
host being quiesced at the same time the filer will automatically take
the snapshot.

Any reason you can't use the "snap sched" command for this?
snap sched volname 0 3 0
This takes a snapshot at midnight and keeps at most 3.
If midnight isn't suitable you can configure the hourly
option to take one hourly per day and keep 3. Suppose you
want 18:00
snap sched volname 0 0 3@18
