This method will not reboot the system. The following set of commands shows 
how to use this script. 

If OpenSM is configured and running, it must be stopped before the openibd 

stop

 command, and must be started after the openibd

 

start command. Omit 

the commands to start/stop opensmd if you are not running it on that node.
The sequence of commands to restart the driver are as follows:

# /etc/init.d/opensmd stop 
# /etc/init.d/openibd stop
...
# /etc/init.d/openibd start
# /etc/init.d/opensmd start 

The

...

 represents whatever activity you are engaged in after infinipath is 

stopped.

An equivalent way to restart the driver this is to use same sequence shown 
previously, except use the restart command instead of start and stop:

# /etc/init.d/opensmd stop 
# /etc/init.d/openibd restart
# /etc/init.d/opensmd start 

You can check to see if opensmd is running by using the following command (as a 

root user); if there is no output, opensmd is not configured to run:

# /sbin/chkconfig --list opensmd | grep -w on

When you need to determine which InfiniPath and OpenFabrics modules are 
running, use the following command. You do not need to be a root user.

$ lsmod | egrep ’ipath_|ib_|rdma_|findex’

You can also unload the driver/modules manually without using 
/etc/init.d/openibd. Use the following series of commands (as a root user):

# umount /ipathfs
# fuser -k /dev/ipath* /dev/infiniband/*
# lsmod | egrep ’^ib_|^rdma_|^iw_’ | xargs modprobe -r

Stopping or restarting openibd terminates any QLogic MPI processes, as 

well as any OpenFabrics processes that are running at the time.
