A snapplan specifies snapshot scenarios for a database (such as online, instant, or offline). You can name a snapplan file whatever you choose.
You can use the dbed_vmchecksnap -o setdefaults option to create the snapplan and set default values for the parameters. You may then modify the snapplan file using a text editor.
You can also use the command to validate, copy, list, or remove a snapplan and check the storage to make sure it is configured appropriately for the Database FlashSnap feature.
