I found out many years ago, ONTAP does NOT in fact send ASUP to customers anymore using the old asup method. I have set it up and it does not always do what is needed. So what do do?
EMS (Event Management System)
There is a simple, easy to follow doc to set it up:
All you need are an email address/group, a SMTP server and away you go!
Take a look. If you want more info, just ask.
