Set the Subnet Manager Priority

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.

1. 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
   -------------------------------------------------
   #

2. Restart the Subnet Manager:

   # disablesm
   Stopping IB Subnet Manager..                               [  OK  ]
   # enablesm
   Starting IB Subnet Manager.                                [  OK  ]
   #
