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

pmdaib

PMDAIB(1)						      General Commands Manual							 PMDAIB(1)

NAME

       pmdaib - Infiniband performance metrics domain agent (PMDA)

SYNOPSYS

       $PCP_PMDAS_DIR/infiniband/pmdaib [-c configFile] [-D debug] [-d domain] [-l logfile] [-w]

DESCRIPTION

       pmdaib is a Performance Metrics Domain Agent (PMDA) which exports information and performance metrics about local Infiniband HCAs and local
       or remote Infiniband GUIDs.

       A brief description of the pmdaib command line options follows:

       -c   Location of the config file.  By default, the config file is named $PCP_PMDAS_DIR/infiniband/config.  See CONFIG FILE for more  infor-
	    mation.

       -D   A debug values, as specified by pmdbg (1)

       -d   Specify an alternate performance metrics domain number.  Almost never necessary.

       -l   Location  of the log file.	By default, a log file named ib.log is written to $PCP_LOG_DIR/pmcd.  If the log file cannot be created or
	    is not writable, output is written to the standard error instead.

       -w   Write out the default config file to $PCP_PMDAS_DIRS/infiniband and exit immediately.  The written config file will contain the  local
	    HCA  ports.   It will not overwrite an existing file.  This argument should only be used to create the template config file and should
	    never appear in pmcd.conf.	See CONFIG FILE for more information on the file format and on monitoring remote GUIDs.

CONFIG FILE

       By default, the PMDA will operate without using a config file.  In this mode of operation the local HCA ports will be monitored.  Note that
       if a new HCA is added to the machine that instance domain naming may change because it will always be based on the kernel's naming.

       In  cases where this is not acceptable, or in the case where monitoring remote Infiniband ports is required, a config file must be created.
       A "template" file can be created by running the pmdaib daemon with the -w argument.  This will create a config file with  the  local  ports
       and GUIDs.

       If the config file is executable then it will be run and the output will be used as the config file.

       The  config  file is composed of line-based records.  Blank lines and everything after the hash (#) character are ignored.  Each line has 6
       fields:

       [instName] [portGUID] [portNum] via [localPortName]:[localPortNum]

       The first field is used to give a static instance name to the Infiniband port that has a specific GUID.	All of the other  fields  must	be
       properly specified in order to monitor a particular port.

       For example, to monitor port 1 of the local HCA called 'mthca0' a possible config file line would be:

       myPort1 0xdeadbeef01234567 1 via mthca0:1

       Remote  ports  can  be  easily monitored by specifying the GUID of the HCA or switch and specifying the remote port number.  The localPort-
       Name:localPortNum tuple specifies which local HCA and port to use as the "first hop" in contacting the remote GUID.  E.g., to monitor  port
       13 of a remote switch which is connected to the fabric on the first port of the second HCA:

       switch13 0xfeeffeefabcdabcd 13 via mthca1:1

LOCAL CONTEXT

       The  Infiniband	pmda also supports accessing the metrics via PM_CONTEXT_LOCAL when using the PMAPI interface.  In order to use the Infini-
       band pmda in this way, set the environment variable PMDA_LOCAL_IB prior to calling pmNewContext(3).
