Restart (as a root user) by typing:

OpenSM is an optional component of the OpenFabrics project that provides a 
Subnet Manager (SM) 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 a root user) to enable it on the node where it will be 

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

You can stop opensmd again by typing:

# /etc/init.d/opensmd stop

If you want to pass any arguments to the OpenSM program, modify the following 
file, and add the arguments to the OPTIONS variable: 

/etc/init.d/opensmd 

„

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 change the setting to SET_IPOIB_CM=no.
