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

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 <http://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.
