If you have no Subnet Managers other than the one within the management controller, you can set the Subnet Manager priority to the lowest value. If you have other Subnet Managers in your InfiniBand fabric, you must decide which is to be the master Subnet Manager. The master Subnet Manager has the highest priority. All other Subnet Managers are slave Subnet Managers, and must have a lower priority.
Identify the prerequisite and subsequent installation tasks that you must perform in conjunction with this procedure.
Create the root node GUID file.
Create the Subnet Manager configuration file.
Determine the priority of the Subnet Manager within the management controller.
Set the priority of the Subnet Manager:
# setsmpriority priority
where priority is 0 (lowest) to 13 (highest). For example, to set the Subnet Manager to priority 13:
# setsmpriority 13 ------------------------------------------------- OpenSM 3.2.6_20090717 Reading Cached Option File: /etc/opensm/opensm.conf Loading Cached Option:routing_engine = ftree Loading Cached Option:sminfo_polling_timeout = 1000 Loading Cached Option:polling_retry_number = 3 Command Line Arguments: Priority = 13 Creating config file template ’/tmp/osm.conf’. Log File: /var/log/opensm.log ------------------------------------------------- #
Enable the Subnet Manager:
# enablesm Starting IB Subnet Manager. [ OK ] #
Attach the InfiniBand cables.
