I have a AFF system running OnTap 9.3P1 and am seeing a strange issue. If we have a DNS entry for the cluster mgmt interface ,that contains an "_" character, I recieve the following error when trying to load the System Manager interface.
Your browser sent a request that this server could not understand.
Additionally, a 400 Bad Request error was encountered while trying to use an ErrorDocument to handle the request.
If I go to the IP address or a DNS entry that doesn't contain an _ I can logon as normal.
Is anyone else seeing this?

Underscores are not valid in DNS hostname entries.
The authoritative answer is in http://www.ietf.org/rfc/rfc952.txt
1. A "name" (Net, Host, Gateway, or Domain name) is a text string up to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus sign (-), and period (.).

agree, it was never a good idea.. i guess that escaped NetApp guys not just once .. ONTAP Cloud default SVM name is created using svm_ prefix .. even today.
