Node GUID: 0x0021280001a0a364
System image GUID: 0x0021280001a0a367
Port 1:
State: Active
Physical state: LinkUp
Rate: 40
Base lid: 120
LMC: 0
SM lid: 6
Capability mask: 0x02510868
Port GUID: 0x0021280001a0a365
Link layer: IB
Port 2:
State: Active
Physical state: LinkUp
Rate: 40
Base lid: 121
LMC: 0
SM lid: 6
Capability mask: 0x02510868
Port GUID: 0x0021280001a0a366
Link layer: IB
In the output, information about two ports is displayed. Identify the GUID
and Base lid of the port that you want to use for creating the VNIC.
For the example illustrated in this procedure, we will use the port with GUID
0x0021280001a0a366 and Base lid 121.
b. On the same compute node, run the following command to view information
about all the active links in the InfiniBand fabric:
hostname# iblinkinfo.pl -R | grep hostname
hostname is the name of the compute node. You can also specify the bonded
IPoIB address of the compute node.
Example:
el01cn01# iblinkinfo.pl -R | grep el01cn01
65 15[ ] ==( 4X 10.0 Gbps Active/ LinkUp)==> 121 2[ ] "el01cn01
EL-C 192.168.10.29 HCA-1" (Could be 5.0 Gbps)
64 15[ ] ==( 4X 10.0 Gbps Active/ LinkUp)==> 120 1[ ] "el01cn01
EL-C 192.168.10.29 HCA-1" (Could be 5.0 Gbps)
From the output of the iblinkinfo command, note the switch lid value
(65, in first column) associated with the Base lid of the compute node port
that you noted earlier (121, in the first line):
4.
Determine the gateway switch that corresponds to the switch LID 65 by running
the ibswitches command, as in the following example:
Example:
el01cn01# ibswitches
Switch : 0x002128548042c0a0 ports 36 "SUN IB QDR GW switch el01gw03" enhanced
port 0 lid 63 lmc 0
Switch : 0x002128547f22c0a0 ports 36 "SUN IB QDR GW switch el01gw02" enhanced
port 0 lid 6 lmc 0
Switch : 0x00212856d0a2c0a0 ports 36 "SUN IB QDR GW switch el01gw04" enhanced
port 0 lid 65 lmc 0
