Actually, no, nodeset didn't return anything. I tried "nodeset xcat-serv1
install". The hyphen in the node name isn't problematic is it? After the
upgrade to 2.8.3 the warning about the SN daemons not being up is gone now
(which is good), but nothing is returned to the console when I do a nodeset
(it completes silently). I don't think it is working, and I didn't see an
entry created for it in /tftpboot/xcat/xnba/nodes/.
Here are the entries in my tables:
*tabdump nodelist:*
