el01cn02# dladm show-ib
LINK HCAGUID PORTGUID PORT STATE PKEYS
ibp0 21280001A0A694 21280001A0A695 1 up FFFF
ibp1 21280001A0A694 21280001A0A696 2 up FFFF
In the output, information about two ports is displayed. From this output,
you must determine which port GUID to use. This example procedure uses
the port GUID 21280001A0A695 (port 1).
b. On the same compute node, run the following command on the command
line to report information about all active links in the InfiniBand fabric:
el01cn02# iblinkinfo.pl -R | grep hostname
Where hostname is the name of the compute node. For example, el01cn02.
The following is the example output of this command:
el01cn02# iblinkinfo.pl -R | grep el01cn02
65
15[ ] ==( 4X 10.0 Gbps Active/ LinkUp)==> 121 2[ ] "el01cn02
EL-C 192.168.10.29 HCA-1" (Could be 5.0 Gbps)
64
15[ ] ==( 4X 10.0 Gbps Active/ LinkUp)==> 120 1[ ] "el01cn02
EL-C 192.168.10.29 HCA-1" (Could be 5.0 Gbps)
From this example output, note down the switch lid values. The switch lid of
port 1 is 64 (the first column in the output). The switch lid of port 2 is 65.
4. Determine which gateway switch is associated with the switch lids by comparing
the first column of the iblinkinfo output to the lid value of the ibswitches
command as follows:
a. On the compute node, run the ibswitches command on the command line.
The example output of this command is as follows:
el01cn02# 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
Switch : 0x00212856d162c0a0 ports 36 "SUN IB QDR GW switch el01gw05"
enhanced port 0 lid 64 lmc 0
b. In this example output, identify the switches that lid values 64 and 65 are
associated with. In this example, the switch lid 64 of the gateway switch
el01gw05 with GUID 0x00212856d162c0a0 is associated with port 1 of
the HCA in the compute node el01cn02.
Note:
This example procedure uses LID 64 of this gateway switch.
5.
Define a dummy MAC address in the following format:
<last three octets from el01gw05 switch ib GUID> : <last
three octets of the administrative IP of the compute node in
hexadecimal format>
