A
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 as above,
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
root); 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 root:
$ lsmod | egrep ’ipath_|ib_|rdma_|findex’
Unloading the Driver/Modules Manually
You can also unload the driver/modules manually without using
/etc/init.d/openibd. Use the following series of commands (as root):
# umount /ipathfs
# fuser -k /dev/ipath* /dev/infiniband/*
# lsmod | egrep ’^ib_|^rdma_|^iw_’ | xargs modprobe -r

See the modprobe(8), modprobe.conf(5), and lsmod(8) man pages for more
information. Also see the file (on Red Hat systems):
/usr/share/doc/initscripts-*/sysconfig.txt
NOTE:
Stopping or restarting openibd terminates any QLogic MPI processes, as
well as any OpenFabrics processes that are running at the time.
