Hi,
I am a linux newbie and I am trying to run ipoib on linux Centos 5.3. My
software driver does not recognize the hardware even though it is connected.

1. I am using the following infiniband HCA
$ my prompt> lspci |grep Mellanox
01:00.0 InfiniBand: Mellanox Technologies MT25208 InfiniHost III Ex (Tavor
compatibility mode) (rev a0)

2. I installed the infiniband utilities using ---> yum groupinstall
'OpenFabrics Enterprise Distribution'

3. I then started the driver in this way -->

[root@localhost ]# /etc/init.d/openibd start
Loading OpenIB kernel modules:                             [  OK  ]
[root@localhost ]# ibv_devinfo
libibverbs: Warning: no userspace device-specific driver found for
/sys/class/infiniband_verbs/uverbs0
No IB devices found

As you can see it says No IB devices found. I am able to detect the hardware
using Windows, however I am not able to detect the same using Linux. Please
guide me as to what I can do.

4. One more Question, As I dug into to the release notes, I find that Centos
5.3 is not supported in the distribution of OFED-1.4. Is this correct? Does
this mean I have to downgrade to centos 5.2?

5. What could be the time frame by which Centos 5.3 is also supported?

Thanks.

regards,
Ashwath
