Before You Begin
The output of some InfiniBand commands identify a node by its GUID. You can determine the switch chip or InfiniBand cable connection associated with that GUID using this procedure.
For example, given this output from the ibdiagnet command:
-W- lid=0x000f guid=0x002128312345c0a0 dev=48438 Port=21
In this example, the GUID is 0x002128312345c0a0 and the port is 21.
For example, GUID 0x002128312345c0a0 is truncated to c0a0.
The c0 means that the node is inside of a Sun Network QDR InfiniBand Gateway Switch. The a means that the node is located in I4 switch chip A, the only switch chip. The port is 21.
# ibswitches Switch : 0x03ba01234567a0a0 ports 36 "SUN DCS 36P QDR mnm-36p-2 10.172.144.66" enhanced port 0 lid 1 lmc 0 Switch : 0x002128312345c0a0 ports 36 "SUN IB QDR GW switch mnm-gw-1 10.172.144.69" enhanced port 0 lid 15 lmc 0 #
For example, using Switch Chip Port to QSFP Connectors and Link LED Routes, I4 switch chip, port 21 routes to connector 1B.
