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.

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.

Greetings,
I take a daily snapshots (named ss-YYYYMMDDHHmm) of several volumes on my filers. I would like to automatically delete the oldest snapshot (assuming it's not busy) when a certain number of snapshots are
present
in the volume (ie, only keep the latest 3 snapshots). Is this
possible?
If not, does anyone have any scripts where it can be done from a host?
TIA,
Daniel
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

I create snapshots all day long using snapdrive.
My question is how to automatically delete snapshots based on the _number_ of snapshots and not space availability (which is what the autodelete setting uses), when those snapshots are taking from the host (ie, snapdrive or regular rsh/ssh command).

The way we do it is by the way we order them:
Pseudo logic:
sdcli snap delete snap.3 sdcli snap rename snap.2 snap.3 sdcli snap rename snap.1 snap.2 sdcli snap rename snap.0 snap.1 sdcli snap create snap.0
