Failed to load HCA driver and Access Layer

Hi All,

I got the following errors when i was trying to restart Infiniband service.

Loading cxgb3 driver : [FAILED]
Loading HCA driver and Access Layer : [FAILED]

The command managed to bring up the services, but without RDMA modules loaded from /etc/init.d/openibd status output. Is the missing of RDMA module has significant impacts on IB connectivity or performance?

It's on SLES 10 SP3.

Appreciate if you could shed light on this.

Many thanks,
Darrell

NAME

       tavor - InfiniHost MT23108/MT25208 InfiniBand (IB) Driver

SYNOPSIS

       PCI   pci15b3,5a44@pci-slot, pci15b3,5a45@pci-slot

       PCI-E pci15b3,6278@pci-e-slot, pci15b3,6279@pci-e-slot

       The  tavor  driver is an IB Architecture-compliant implementation of an HCA, which operates on the Mellanox MT23108 InfiniBand ASSP and the
       Mellanox MT25208 InfiniBand ASSP. These ASSP's support the  link and physical layers of the InfiniBand specification, while  the  ASSP  and
       the driver support the transport layer.

       The  tavor  driver  interfaces with the InfiniBand Transport Framework (IBTF) and provides an implementation of the Channel Interfaces that
       are defined by that framework. It also enables management applications and agents to access the IB fabric.
