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
ibtl - Solaris InfiniBand Transport Layer DESCRIPTION
InfiniBand (IB) is an I/O technology based on switched fabrics. The Solaris InfiniBand Transport Layer (IBTL) is a Solaris kernel misc mod- ule and adheres to the IB Architecture Version 1.1 specification and provides a transport layer abstraction to IB client drivers. IBTL implements the programming interfaces for the Solaris InfiniBand Transport Framework (IBTF), consisting of the IB Channel Interface (CI) and the IB Transport Interface (TI). The CI consists of Host Channel Adapters (HCAs) and HCA drivers. A host is attached to the IB fabric through the CI layer. The Solaris InfiniBand CI is Sun's API rendering of the InfiniBand Architecture (IBTA) "verbs" specification. The Solaris InfiniBand TI is the kernel service driver interface into the Solaris InfiniBand Transport Framework. It provides transport and communications setup programming interfaces for Unreliable Datagram (UD) and Reliable Connected (RC) transport types only. FILES
