Thanks Aaron, you didn't quite answer the question I asked. I can see the network as I noted in the original email, by using the shorthand
lsdef -t network ib the problem I am seeing is that new machines on that network are not having the network appear in the search field in their /etc/resolv.conf. IE. I have networks gen and ib. Some machines are only on gen. Some are on both. node01 and node03 are on both. After following all the documentation, I start node01 and node03 and they install. At the end of the installation, I login to each and: [root@node01 ~]# cat /etc/resolv.conf ; generated by /usr/sbin/dhclient-script search gen. domain.com.au nameserver 10.197.35.201 [root@node03 ~]# cat /etc/resolv.conf # Generated by NetworkManager search gen domain.com.au nameserver 10.197.35.201 The difference here is node01 has confignetwork is in postbootscripts and node03 has confignetwork in postscripts My main concern is that the network ib isn't appearing in the search field of the node's /etc/resolv.conf. A secondary uncertainty is why changing when confignetwork runs changes how resolv.conf is built (dhclient vs NetworkManager) I have been reading and re-reading the documentation (and submitting bug reports/pull requests when I'm finding glaring errors), but I am new to xcat, new to Infiniband and networking has never been a strong suit.
