Tracing End-to-End IB Path Continuity
A diagnostic command that supports tracing the IB path from host server, through
the IB Fabric, to the I/O module that terminates the IB path on the Oracle Fabric
Interconnect. This new functionality is helpful as a top-level of troubleshooting
information if virtual resources are encountering a problem, or if you suspect a
problem with the IB path between hosts and the Oracle Fabric Interconnect.
Displaying the IB path is supported through the show diagnostics ib-path
command. When you issue this command, the entire IB path is displayed including
the individual links that comprise the overall IB path. For example, a typical IB path
might contain:
■ A link from a host server’s HCA to an IB switch that is sitting between the host
and the Oracle Fabric Interconnect.
■ A link from the IB switch to the Oracle Fabric Interconnect.
■ One or more links within each Oracle Fabric Interconnect that correspond to links
between the hardware on the Oracle Fabric Interconnect’s Fabric Board.
■ A link from the Fabric Board to the I/O module where virtual resources on the IB
link are terminated.
At each of these individual links, performance statistics and error counters are
tracked and displayed in a table so that you can check the functionality of the IB
path at different points. The show diagnostics ib-path command has the
following syntax:
Note – Virtual resources must be deployed to the I/O card for which you want to
display the IB path. If you issue this command and nothing is displayed, no vNICs
or vHBAs are configured on the server.
Additional notes about using the command:
■ Statistics are not polled or refreshed at regular intervals, so you must explicitly
issue the command every time you want to display a fresh or updated set of
statistics.
