Hi xCAT List,

For some time we have been under the impression that we needed to define a 
separate DNS sub-domain for each xCAT management node (i.e. each xCAT 
cluster) that we have in our environment.

I notice in the fine print of the release notes for xCAT 2.7 that xCAT can 
now update an external DNS server using the makedns -e option.  Does this 
mean that multiple xCAT management nodes (managing different clusters) can 
now share a single DNS sub-domain?  Or is it still recommended that each 
cluster be part of a separate DNS sub-domain?

If we use makedns -e, do the DNS zone files for forward and reverse name 
resolution need to be already defined on the external DNS server i.e. does 
the makedns -e command only update existing DNS zones or can it create new 
zones?
