ibdiagnet Command

Performs InfiniBand fabric diagnostic.


ibdiagnet [-c count][-v][-r][-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][-skip checks][-load_db file][-h][-V]



This InfiniBand command scans the InfiniBand fabric using directed route packets, extracting all the available information regarding the connectivity and devices. 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.
List of all the nodes, ports, and links in the fabric.
Dump of the unicast forwarding tables of the fabric switches.
Dump of the multicast forwarding tables of the fabric switches.
In case of duplicate port/node GUIDs, this file includes the map between masked GUIDs and real GUIDs.
List of all the Subnet Manager (state and priority) in the fabric.
Dump of the Performance Manager counters values, for the fabric links.
Dump of the existing partitions and their member host ports.
Dump of the multicast groups, their properties, and member host ports.
Dump of the internal subnet database. You can load this file in later runs using the -load_db option.

During the discovery phase, the command also checks for duplicate node/port GUIDs in the InfiniBand fabric. If such an error is detected, it is displayed on the standard output.

After the discovery phase is completed, directed route packets are sent multiple times to detect possible problematic paths on which packets might be lost. A report of suspected bad links is displayed on the standard output.

If requested with the -r option, a full report of fabric qualities is displayed, including:

Note - If the InfiniBand fabric includes only one CA, then CA-to-CA paths are not reported. Additionally, if a topology file is provided, the ibdiagnet command uses the names defined in the topology file for the output reports.

The ibdiagnet command is available from the /SYS/Fabric_Mgmt Linux shell target of the Oracle ILOM CLI interface.


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

Sets the minimum number of packets sent across each link.
Provides verbose output.
Provides a report of fabric qualities.
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.
Uses the Performance Manager counter of PM set to the threshold of value.
Skips the executions of the selected checks. One or more checks can be specified.
Writes out the discovered topology into the given file.
Loads subnet data from the given .db file and skips the subnet discovery stage.

Note - Some checks require actual subnet discovery and are disabled if load_db is specified. Those checks are for duplicate/zero GUIDs, link state, and Subnet Manager status.

Provides help.
Displays the version information.

The following example shows how to test the InfiniBand fabric with the ibdiagnet command. The command checks for 4x link width and 10 Gbyte/sec speed, dumps the Performance Manager counters, and then clears them.

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