Location: DNS Functions/Establish a Trust Relationship with a Primary Nameserver
You can establish a master/primary nameserver relationship at your server setup level. Refer to Editing your server setup for more information. If you do set up a primary nameserver, you need to establish a trust relationship between the two servers so that you can add all DNS entries from the primary nameserver. This saves you from having to log on to multiple servers to set up various DNS entries.
NOTICE: This function is handled automatically when DNS clustering is enabled. There is nothing to set up.
