I think so. First you cooperate network names must be in DNS and
/etc/hosts. When you create a client you can specify the NIS server just
put in the host name gremio instead of gremio_i it will use that network to
talk with the NIS master.

Subject: NIS question for "conoisseurs".
Fellow AIXers,
We have, in our company, a two-frame RS/6000SP system and three standalone
RS/6000 hosts.
The first SP tower has four nodes and the second one, three nodes.
Three networks interconnect these nodes:
i) the corporate network, 10.1/16 (hostnames with no special suffix);
ii) the administrative network, 172.16/16 (hostnames with _i suffix);
iii) the "fast-switching" internal network, 172.17/16 (hostnames with _sw
suffix).
The administrative network (ii) connects the nodes in each frame with
control workstations which are used to manage that frame. Please note, the
administrative network does not link one frame with the other. The
"fast-switching" network (iii) connects the nodes in each frame and the
switches are interconnected in order to assure inter-frame communication.
The corporate network is "seen" by every AIX machine in our network and all
their clients.
We have a problem with NIS configuration. In our first AIX installation we
(mistakenly I presume) configured the "default hostname" to be the
_i-terminated one (i.e. the "administrative network" name). So if the DNS
(corporate) name would be "gremio", we configured it to be "gremio_i", which
resolves to 172.16.X.Y. The problem is, if we assign "gremio_i" as the NIS
master server, it is only "seen" by hosts in the same frame (because NIS
tries to communicate over the "administrative network", which does not link
SP frames), and worse, it is not seen by machines outside the SP frames.
Changing the hostname is not an option, as we have software which depends on
the "default hostname" for its licensing (e.g. OpenIngres). Using the
switched network is not another option, because that network is not seen by
other AIX (i.e. non-SP) hosts.
My question is, is there a way to force NIS to ignore the "default
hostnames" and to comunicate ONLY by the corporate network, even if NIS
masters and slaves are SP nodes?
Thanks for your advice,
Marlon.
