What version of openib are you using? If this is gen2 (openfabrics), then
you need the following in modprobe.conf:
options lnet networks="o2ib0"
When you have this, then you can successfully run the following:
# modprobe lnet
# lctl network up
If everything goes well, you will see some output in dmesg that looks
something like:
Lustre: Added LNI <IB0InterfaceAddress>@o2ib [8/64]
At this point, you can run ?/usr/sbin/lctl list_nids? and see what nids are
available on your system.
If I understand anything, you?ll need an ipoib interface up for the initial
connection between client and server (after that everything is passed with
lower level IB protocols). If someone knows otherwise, please let me know
(as I?m interested in learning more about it).
