Understanding Service Procedures
Often you need to know the route between two nodes. The ibtracert command can provide that information by displaying the GUIDs, ports, and LIDs of the nodes along the route.
On the management controller, type:
# ibtracert slid dlid
where:
slid is the LID of the source node.
dlid is the LID of the destination node.
For example:
# ibtracert 25 24 From switch {0x0021283a8620b0f0} portnum 0 lid 25-25 "Sun DCS 72 QDR FC switch o4nm2-72p-2" [1] -> switch port {0x0021283a8620b0c0}[9] lid 22-22 "Sun DCS 72 QDR switch 1.2(LC)" [2] -> switch port {0x0021283a8620b0e0}[8] lid 24-24 "Sun DCS 72 QDR switch 1.1(FC)" To switch {0x0021283a8620b0e0} portnum 0 lid 24-24 "Sun DCS 72 QDR switch 1.1(FC)" #
For this example:
The route starts at switch with GUID 0x0021283a8620b0f0 and is using port 0. The switch is LID 25 and in the description, the switch host’s name is o4nm2-72p-2.
The route enters at port 1 of the switch with GUID 0x0021283a8620b0c0 and exits at port 9. The switch is LID 22.
The route enters at port 2 of the switch with GUID 0x0021283a8620b0e02 and exits at port 8. The switch is LID 24.
Note - The output for your InfiniBand fabric will differ from that in the example.
