Sahana,
Unfortunately I am pretty sure dynamic DNS won't help me. I need the DNS entry on my DR netapp to be what the Primary netapp was. Dynamic DNS would possibly work if I didn't have SVM and lifs that could move around where the same name always gets to the correct machine but i don't think that dynamic DNS can work to get DR netapp to send the name of the failed SVM, unless I was maybe doing svm failover?
