How to find which switch the OpenSM is running on


1. On any clients do a ibstat

CA type: MT26428
        Number of ports: 2
        Firmware version: 2.9.1000
        Hardware version: b0
        Node GUID: 0x000xxxxxxxxxx
        System image GUID: 0xxxxxxxxxxxxxxxx
        Port 1:
                State: Active
                Physical state: LinkUp
                Rate: 40
                Base lid: 184
                LMC: 0
                SM lid: 1
                Capability mask: 0x02510868
                Port GUID: 0x0002c903005abfd7
                Link layer: InfiniBand

2. To check for the SM Manager

# smpquery ND -L 1
Node Description:.......Voltaire 4036 # 4036-0D9E

where 1 is the SM Lid:1

3. If you query InfiniBand SMInfo attribute

# sminfo
sminfo: sm lid 1 sm guid 0x8f10500200d9e, activity count 42554 priority 4 state 3 SMINFO_MASTER
