Lustre discuss - Dec 2009 - OFED - How to configure infiniband interface on Linux

Hi Guys,

I have another quick question.  I will need to configure my infiniband
interfaces and I guess the best method is to use the kernel-ib modules that
lustre.org provides instead of using the ones from the vendor.  Is there any
documentation that you can point me to that would help me configure these
new interfaces?  I am brand new to infiniband and don''t have too much
experience with this.  I will be adding this to both a RHEL 5.3 and SLES 11
systems.

Thanks in advance.

Jagga,

There is no any special process of enabling IB on linux. You just 
install rpms from lustre.org (lustre + kernel + ib), reboot system and 
look at ''ifconfig -a'' output. If all went fine,
you''ll see ''ib0''
interface in the output and you can configure it with ''ifconfig ib0
...''
in the same way as you configure eth0. As soon as it is ''up''
and has an
IP-address assigned, you can run lustre over it.

Another approach is to build all from sources. If you choose to do so, 
the following link is useful: http://blogs.sun.com/atulvid/
(kudos to Atul for detailed guidelines).

Sincerely,
Maxim

Jagga -

The Configuring Infiniband Connectivity page on lustre.org may also be 
helpful:
