The output of the ping command will be similar to the following, with a line
for each host already configured and connected:

OpenSM
OpenSM is an optional component of the OpenFabrics project that provides a
subnet manager for InfiniBand networks. This package can be installed on all
machines, but only needs to be enabled on the machine in the cluster that will act
as a subnet manager. You do not need to use OpenSM if any of your InfiniBand
switches provide a subnet manager, or if you are running a host-based SM.
If you are using the Installer tool, you can set the OpenSM default behavior at the
time of installation.
If you are using the rpm install method, note that after installing the opensm
package, OpenSM is configured to be off after the next machine reboot. It only
needs to be enabled on the node that acts as the subnet manager, so use the
chkconfig command (as root) to enable it on the node where it is to run:
# chkconfig opensmd on
The command to disable it on reboot is:
# chkconfig opensmd off
You can start opensmd without rebooting your machine by typing:
# /etc/init.d/opensmd start
NOTE:
The configuration must be repeated each time the system is rebooted.
IPoIB-CM (Connected Mode) is enabled by default. The setting in
/etc/infiniband/openib.conf is SET_IPOIB_CM=yes. To use
datagram mode use SET_IPOIB_CM=no.
