Understanding Service Procedures
By default, the Subnet Manager within the management controller is set to 0 priority. If there is more than one Subnet Manager in your InfiniBand fabric, you must set the Subnet Managers’ priorities appropriately. The Subnet Manager with the highest priority is the master Subnet Manager.
Note - Setting Subnet Managers of the same fabric to the same priority can have undesirable results.
On the management controller, type:
# setsmpriority priority
where priority is 0 (lowest) to 13 (highest). For example:
# setsmpriority 3 ------------------------------------------------- OpenSM 3.2.6_20090717 Reading Cached Option File: /etc/opensm/opensm.conf Loading Cached Option:routing_engine = ftree Loading Cached Option:sm_priority = 13 Loading Cached Option:sminfo_polling_timeout = 1000 Loading Cached Option:polling_retry_number = 3 Command Line Arguments: Priority = 3 Creating config file template ’/tmp/osm.conf’. Log File: /var/log/opensm.log ------------------------------------------------- #
Restart the Subnet Manager:
# disablesm Stopping IB Subnet Manager.. [ OK ] # enablesm Starting IB Subnet Manager. [ OK ] #
