4. Clear the counters on the server (brick) to get a fresh batch of statistics.
5. Issue the show diagnostics ib-path command for the server (brick) to
display the IB path and counters.
The output of the command is displayed in a top-down manner, which represents
the IB path’s flow from the server to the module that terminates the IB path on
the Oracle Fabric Interconnect. In this example, color is used to illustrate the IB
path flow, and also to differentiate the various links in the overall IB path.
■ The red text indicates the server HCA as one end of the IB path. The LID/Port
field indicates the IB local ID and the HCA port on which the IB path exists. The
width/speed show that the HCA is in QDR mode.
■ the green text shows a link in the overall IB path. This link shows that an IB
switch exists between the host/HCA and the Oracle Fabric Interconnect. Two
entries are present—one for the ingress point and one for the egress point. Entries
in the table are always ordered with the ingress point on top in keeping with
overall flow of the IB path from the server to the Oracle Fabric Interconnect. The
lid/port field shows local ID and port that are supporting the IB path on the IB
switch.
