Thank you, Yuan and Christian!
Yuan, I haven't tried it, but it seems that your suggestion would not
actually solve my problem. Makehosts would generate, as you were saying,
this line:
192.168.20.2 hpcmn-test-eth1 hpcmn-test.kkeane.sandiego.edu
But the DNS server should only listen on 192.168.101.2. That is why I my
preferred solution would be to change the zones to have an NS record that
actually points to the correct NIC: hpcmn-test.imm.sabre.kkeane.sandiego.edu

Christian - you are right. Putting the names into the "hostnames" field was
a bit of a hack. It actually works if there is only one name in that field,
but if there are multiple names in that field, makehosts seems to only use
the last one. And it also seems to *replace* rather than add to the names
that xCAT would ordinarily use.
