Russell,
Thanks for investigating it and giving the feedback. I'll add the '[
"$gateway" == "<xcatmaster>" ]' part in the code to handle the
situation.

Subject: Re: [xcat-user] using gateway=<xcatmaster> in networks
table
The following modification fixes the original issue that I saw with the
configib script in xCAT v2.8.4 – namely, that the value for gateway that
gets set in ifcfg-ib0 is: gateway=<xcatmaster>
if [ "$gateway" == "<xcatmaster>" ] || [ "$gateway" ==
"<xcatmaster>" ]; then
gateway=''
fi
I suspect that the Perl code that reads the tables and sends the values to
the postscript must be passing the gateway value through some kind of
filter that changes the less-than and greater-than symbols to a
web-compatible format.
No action here since things look to be very different in version 2.8.5
with regard to ‘configib’.
I just wanted to close the loop on this issue and have this info out there
for future reference.

The whole reason I’m trying to make “configib” work is that I don’t want
to install Mellanox drivers.
I’ll probably end up moving ‘confignics’ to the postbootscripts, but I
would like to determine what the root cause is here. I’ll let you know
what I find.

Russell,
Thanks a lot for all detailed information. From the xcat.log and the
fact that updatenode produced the correct result it looks like the
corrected packages for IB were installed, but the module was not loaded
when the postscript confignics was running.
I checked the documentation
https://sourceforge.net/p/xcat/wiki/Managing_the_Mellanox_Infiniband_Network1/
it looks like you need to add another postscript in order to have the
Mellanox driver installed. Please check the section "Mellanox IB Drives
Installation".
You need to add mlnxofed_ib_install to the postscript before confignics.
Another way to try is to move confignics from postscripts to
postbootscripts.
Hope it helps,

I noticed that code in the script as well.
I reran the script via “updatenode node1 -P confignics” and it works as
expected when you do that; The GATEWAY line is omitted from the ifcfg-ib0
file.
However, a fresh installation of the OS (statefull) results in the file
getting the incorrect gateway value.
I’ve posted the xcat.log below. You can see that there’s some kind of
trouble when the configib script runs.
It looks like some of the IB modules aren’t initially loaded, so when the
script brings down the driver stack and starts it, there are errors
related to kernel modules. This looks like it’s injecting characters into
the script and that’s causing the script to fail.

My packages list contains “@infiniband” – I also initially tried a shorter
list of known required IB packages. In each case, the result was the same.
If you notice, there are no user-space modules loaded when the postscript
runs.

Hmm, In the /install/postscripts/configib file, it has the following lines
that should prevent "gateway" being written to the configuration file if
it is <xcatmaster>.
if [ "$gateway" == "<xcatmaster>" ]; then
gateway=''
fi
I checked the configuration for node1 and it seems all correct.
Can you download the latest configib script from the following link and
copy it to /install/postscripts directory on you management node and
service nodes (if any). And then run "updatenode node1 confignics" ? See
if it works for you.
