Controlling the Subnet Manager
Set the Subnet Manager Priority
Start the Subnet Manager With the opensmd Daemon
The opensmd daemon uses the opensm.conf file to configure the OpenSM Subnet Manager. You must create an opensm.conf file that is optimized for the Sun Datacenter InfiniBand Switch 72.
On the management controller, stop the OpenSM Subnet Manager.
If a /etc/opensm/opensm.conf file does not exist, create one:
# opensm --create-config /etc/opensm/opensm.conf ------------------------------------------------- OpenSM 3.3.2_20090831_ce6f8dd Command Line Arguments: Creating config file template ’/etc/opensm/opensm.conf’. Log File: /var/log/opensm.log ------------------------------------------------- #
The /etc/opensm/opensm.conf file is created.
Open the /etc/opensm/opensm.conf file in a text editor.
Find the following parameters and change them to as listed.
sweep_interval 120
routing_engine ftree
use_ucast_cache TRUE
root_guid_file /etc/opensm/guid.txt
Note - If the /etc/opensm/guid.txt file does not exist, you must create it. See Create the guid.txt File.
Save the /etc/opensm/opensm.conf file.
Set the permissions for the /etc/opensm/opensm.conf file:
# chmod 0644 /etc/opensm/opensm.conf #
