Controlling the Subnet Manager
Set the Subnet Manager Priority
Start the Subnet Manager With the opensmd Daemon
If you want to quickly determine your Subnet Manager’s priority and state, the sminfo command can also provide the LID and GUID of the hosting HCA.
On the management controller, type:
# sminfo
For example:
# sminfo sminfo: sm lid 25 sm guid 0x21283a8620b0f0, activity count 44911 priority 13 state 3 SMINFO_MASTER #
In the output, the Subnet Manager’s hosting HCA has LID 25 and GUID 0x21283a8620b0f0. The Subnet Manager has a priority of 13 (high) and its state is 3 (master).
