No worries. Here is all the info you could ever want about snapmirror.allow in 8.0:
Using FilerView, navigate to SnapMirror --> Remote Access --> Manage and make sure that the destination filer is listed there. If not, add it using the "Add Remote Access Entry" button.
Basically, this controls the specific systems that the filer can snapmirror to. Note that this is on a controller basis - so you need to specify "ToasterA" and "ToasterB".
You can also edit this file either from the command line or opening the file by using CIFS. If you edit it directly, as always, be sure to create a backup file.
