When you configure SSH, you must log in as the maintenance user. This is because root access to VASA Provider has been disabled. If you use other login credentials, you cannot use SSH to access VASA Provider.

Steps

From the vCenter Server, open a console to the ONTAP tools.
Log in as the maintenance user.
Enter 3 to select System Configuration.
Enter 6 to select Enable SSH Access.
Enter y in the confirmation dialog box.
