OpenFabrics Issues

This section covers items related to OpenFabrics, including OpenSM.

C.5.1

Stop OpenSM Before Stopping/Restarting InfiniPath

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]

C.5.2

Load and Configure IPoIB Before Loading SDP

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.

C.5.3

Set $IBPATH for OpenFabrics Scripts

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
