[openib-general] 2.6.12 Kernel OpenIB support

[Talal jaafar]

Thanks for the help, I was able to load the infiniband drivers using
your suggestion. However, I am still stuck at one point. I do not
understand why is it happening but here what I am getting when I try
to run "service network restart"

 ------------------------------------------------------------------
Shutting down interface eth0:      [OK]
Shutting down interface ib0:       [OK]
Shutting down interface ib1:       [OK]
Shutting down loopback interface:  [OK]
Setting network parameters:        [OK]
Bringing up loopback interface:    [OK]
Bringing up interface eth0:        [OK]
Bringing up interface ib0:  Error, some other host already uses
address 20.1.1.10.
Bringing up interface ib1:  Error, some other host already uses
address 20.1.1.11.
-------------------------------------------------------------------


I am 100% sure that no other host is already using the same address,
and here is how I am setting the ib interfaces:

The output of /etc/sysconfig/network-scripts/ifcgf-ib0 :
---------------------------------------------
DEVICE=ib0
BOOTPROTO=static
ONBOOT=yes
IPADDR=20.1.1.10
NETMASK=255.0.0.0
---------------------------------------------

and the output of /etc/sysconfig/network-scripts/ifcgf-ib1 :
---------------------------------------------
DEVICE=ib1
BOOTPROTO=static
ONBOOT=yes
IPADDR=20.1.1.11
NETMASK=255.0.0.0
--------------------------------------------


Had anybody run into this problem??


Regards,

 Talal
