I just took a look at the code in /opt/xcat/lib/perl/xCAT/Template.pm:
tabdb that handles the table attr substitutions in templates, and it is not
smart enough to handle this type of attribute. It can only handle simple
attribute substitution like
IPADDR="TABLE:nics:$NODE:nicips#
Since the full nics.nicips attribute is really a comma-delimited string of
the different nic ips, the code does not have the logic to parse out a
single value from that string and does not know how to figure out
"nicips.ib0".
I have opened a defect to handle this case:
https://sourceforge.net/p/xcat/bugs/4200/
but we probably won't be able to get to it before xCAT 2.9 timeframe.
Sorry about that. For now it is a limitation in our table attribute
substition support.

Subject: [xcat-user] Trouble accessing nicips.<nicname> sub attributes
Hello,
I've got a pretty simple xCAT template macro like so:
IPADDR="TABLE:nics:$NODE:nicips.ib0#
When I run 'nodeset' I get ugly output like
nodeset compute-7-28 osimage=centos-x86_64-install-compute
compute-7-28: Error: Unable to find requested nicips.ib0 from nics, with
node=compute-7-28
Error: Some nodes failed to set up install resources on server hatteras,
aborting
The entry for this node in my 'nics' table looks like:
"compute-7-28","ib0!10.4.31.2,em1!10.4.15.2","ib0!.ib",,"ib0!Infiniband,em1!Ethernet",,"ib0!infiniband,em1!kickstart",,,
Problem is consistent for any node name -- just using compute-7-28 as an
example.
Also, an `lsdef` shows that xCAT is in no way confused about the entries
in my nics table:
# lsdef compute-7-28
Object name: compute-7-28
...
nichostnamesuffixes.ib0=.ib
nicips.ib0=10.4.31.2
nicips.em1=10.4.15.2
nicnetworks.ib0=infiniband
nicnetworks.em1=kickstart
nictypes.ib0=Infiniband
nictypes.em1=Ethernet
...
I'm confused about how to get at the IP address for this infiniband
interface via the nics table from a kickstart template macro. Other
similar macros seem to work fine. My only suspicion is that perhaps I'm
not handling the sub-attribute in the right way, syntax-wise. Any ideas?
