the `domain` name define in the site is different from `nslookup` output.
from the site table, the /etc/resolv.conf file should looks like
search mendel.sdmz.amnh.org
nameserver 192.168.247.254
can u show me "ip addr show" ? is your makedhcp command working?
Thanks,
Casandra Qiu

check your /etc/resolv.conf, you can get rid of 169 ip address and use
head's ip address, then run makedns again.

Subject: [EXTERNAL] [xcat-user] Erroneous DNS entry creation
CentOS 8
xCat 2.16
When running makedns there is an entry created for an entry that is not in
my /etc/hosts. The effect of this is that the head node has 2 entries in
the local DNS cache. One for its private IP address (in /etc/hosts) and one
for the other address which is not reachable by the compute nodes. The
other IP address is just used by the HW management utilities for internal
communications and is a 169.x.x.x address. How can I tell xCat/makedns to
not create this entry?
