2 – InfiniPath Cluster Administration
Starting and Stopping the InfiniPath Software

Q
To disable the driver on the next system boot, use the command (as root):
# chkconfig infinipath off
NOTE: This does not stop and unload the driver, if it is already loaded.
You can start, stop, or restart (as root) the InfiniPath support with:
# /etc/init.d/infinipath [start | stop | restart]
This method will not reboot the system. The following set of commands shows how
this script can be used. Please take note of the following:
■ You should omit the commands to start/stop opensmd if you are not running it
on that node.
■ You should omit the ifdown and ifup step if you are not using ipath_ether
on that node.
The sequence of commands to restart infinipath are given below. Note that this
next example assumes that ipath_ether is configured as eth2.
# /etc/init.d/opensmd stop
# ifdown eth2
# /etc/init.d/infinipath stop
...
# /etc/init.d/infinipath start
# ifup eth2
# /etc/init.d/opensmd start
The ... represents whatever activity you are engaged in after InfiniPath is stopped.
An equivalent way to specify this is to use same sequence as above, except use
the restart command instead of start and stop:
# /etc/init.d/opensmd stop
# ifdown eth2
# /etc/init.d/infinipath restart
# ifup eth2
# /etc/init.d/opensmd start
NOTE: Restarting InfiniPath will terminate any InfiniPath MPI processes, as well
as any OpenFabrics processes that are running at the time. Processes
using networking over ipath_ether will return errors.
You can check to see if opensmd is running by using the following command; if
there is no output, opensmd is not configured to run:
# /sbin/chkconfig --list opensmd | grep -w on
You can check to see if ipath_ether is running by using the following command.
If it prints no output, it is not running.
$/sbin/lsmod | grep ipath_ether
