ibdiagnet.log -

A dump of all the application reports generate according to the provided flags

ibdiagnet.lst -

List of all the nodes, ports and links in the fabric

ibdiagnet.fdbs -

A dump of the unicast forwarding tables of the fabric switches

ibdiagnet.mcfdbs -

A dump of the multicast forwarding tables of the fabric switches

ibdiagnet.masks -

In case of duplicate port/node Guids, these file include the map between masked Guid and real Guids

ibdiagnet.sm -

List of all the SM (state and priorty) in the fabric

ibdiagnet.pm -

A dump of the pm Counters values, of the fabric links

In addition to generating the files above, the discovery phase also checks for duplicate node/port GUIDs in the IB 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 (according to the -c option) to detect possible problematic paths on which packets may be lost. Such paths are explored, and a report of the suspected bad links is displayed on the standard output.

After scanning the fabric, if the -r option is provided, a full report of the fabric qualities is displayed. This report includes:

* SM report

* Number of nodes and systems

* Hop-count information

maximal hop-count, an example path, and a hop-count histogram

* All CA-to-CA paths traced

* Credit loop report

* mgid-mlid-HCAs matching table

Note: In case the IB fabric includes only one CA, then CA-to-CA paths are not reported. Furthermore, if a topology file is provided, ibdiagnet uses the names defined in it for the output reports.

-c <count> :

Min number of packets to be sent across each link (default = 10)

-v :

Enable verbose mode

-r :

Provides a report of the fabric qualities

-t <topo-file> :

Specifies the topology file name

-s <sys-name> :

Specifies the local system name. Meaningful only if a topology file is specified

-i <dev-index> :

Specifies the index of the device of the port used to connect to the IB fabric (in case of multiple devices on the local system)

-p <port-num> :

Specifies the local device's port num used to connect to the IB fabric

-o <out-dir> :

Specifies the directory where the output files will be placed (default = /tmp)

-lw <1x|4x|12x> :

Specifies the expected link width

-ls <2.5|5|10> :

Specifies the expected link speed

-pm :

Dump all the fabric links, pm Counters into ibdiagnet.pm

-pc :

Reset all the fabric links pmCounters

-P <PM=<Trash>> :

If any of the provided pm is greater then its provided value, print it to screen

-h|--help :

Prints the help page information

-V|--version :

Prints the version of the tool

--vars :

Prints the tool's environment variables and their values
