ibdiagpath Command

Traces the InfiniBand fabric diagnostic path.


ibdiagpath -n[src_name,]dst_name|-l[src_lid,]dst_lid|-d p1,p2,p3,...[-c count][-v][-o outputdir][-t topology][-s system][-i device][-p port][-wt topology][-pm][-pc][-P PM = value][-lw 1x|4x|12x][-ls 2.5|5|10][-h][-V]



This InfiniBand command traces a path between two endpoints and provides information regarding the nodes and ports traversed along the path. The command uses device-specific health queries for the different devices encountered. The way the ibdiagpath command operates is determined from the addressing mode specified on the command line:

In LID route addressing, the actual path from the local port to the source port, and from the source port to the destination port, is defined by means of Subnet Management Linear Forwarding Table queries of the switch nodes along those paths.

Note - When the ibdiagpath command queries the performance counters along the path between the source and destination ports, the command always traverses the LID route, regardless of whether a directed route is specified. If one or more links along the LID route are not in the Active state, the ibdiagpath command reports an error.

This command produces a set of files in the output directory. By default, the output directory is /tmp. The following table describes the files.

File Name
Dump of all the application reports generated according to the provided flags.
Dump of the Performance Manager counters values, for the fabric links.

The following table describes the options to the ibdiagpath command and their purposes:

Identifies the source and destination ports.
Identifies the source and destination LIDs.
Sets directed route from the local node to the destination node.
Sets the minimum number of packets sent across each link.
Provides verbose output.
Specifies the topology file name.
Specifies the local system name.
In the case of multiple devices on the local system, this option specifies the index of the device of the port used to connect to the InfiniBand fabric.
Specifies the local device port number used to connect to the InfiniBand fabric.
Specifies the output directory.
Specifies the expected link width.
Specifies the expected link speed.
Dumps all the fabric link Performance Manager counters into
Resets all the fabric link Performance Manager counters.
Use the Performance Manager counter of PM set to the threshold of value.
Provides help.
Displays the version information.

The following example shows how to display the route from LID 15 to LID 14 with the ibdiagpath command.

Note - The output for your InfiniBand fabric will differ from that in the example.
