Q

This section covers items related to OpenFabrics, including OpenSM.

OpenSM must be stopped before stopping or restarting InfiniPath. If not, error 
messages such as the following will occur:

# /etc/init.d/infinipath stop

Unloading infiniband modules: sdp cm umad uverbs ipoib sa ipath 

mad coreFATAL:Module ib_umad is in use.

Unloading infinipath modules FATAL: Module ib_ipath is in use.

[FAILED]

SDP will generate "Connection Refused" errors if it is loaded before IPoIB has been 
loaded and configured. Loading and configuring IPoIB first should solve the 
problem.

The environment variable $IBPATH should be set to 

/usr/bin

. If this has not been 

set, or if you have it set to a location other than the installed location, you may see 
error messages similar to this when running some OpenFabrics scripts:

/usr/bin/ibhosts: line 30: /usr/local/bin/ibnetdiscover: No such 

file or directory

For the OpenFabrics commands supplied with this InfiniPath release, you should 
set the variable (if it has not been set already), to 

/usr/bin

 as follows:

$ export IBPATH=/usr/bin

The following section gives details on locating problems related to system 
administration.
