SYNOPSYS
ibdiagnet [-c <count>] [-v] [-r] [-vlr] [-u] [-o <out-dir>]
[-t <topo-file>] [-s <sys-name>] [-i <dev-index>] [-p
<port-num>] [-wt]

[-lw <1x|4x|12x>] [-ls <2.5|5|10>]
[-skip <ibdiag_check/s>] [-load_db <db_file>]
DESCRIPTION
ibdiagnet scans the fabric using directed route packets and
extracts all the available information regarding its
connectivity and devices. It then produces the following
files in the output directory (which defined by the -o
option (see below)).
FILES
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 priority) in the fabric
ibdiagnet.pm -
A dump of the pm Counters values, of the fabric links
ibdiagnet.pkey -
A dump of the the existing partitions and their member
host ports
ibdiagnet.mcgs -
A dump of the multicast groups, their properties and
member host ports

IB DIAGNOSTIC PACKAGE IBDIAGNET(1)
ibdiagnet.psl -
A dump of the path record SL of each possible source
node guid and DLID pairs. Created only if -vlr option
is provided
ibdiagnet.slvl -
A dump of the SL2VL Tables from all the switches.
Created only if -vlr option is provided
ibdiagnet.db -
A dump of the internal subnet database. This file can be
loaded in later runs using the -load_db option
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:
o SM report
o Number of nodes and systems
o Hop-count information
histogram
maximal hop-count, an example path, and a hop-count
o All CA-to-CA paths traced
o Credit loop report
o mgid-mlid-HCAs multicast group and report
o Partitions report
o IPoIB report
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.
OPTIONS
-c <count> :
IBDIAG 1.0 Last change: 2014-06-17 2
IB DIAGNOSTIC PACKAGE IBDIAGNET(1)
Min number of packets to be sent across each link
(default = 10)
-v :
Enable verbose mode
-r :
Provides a report of the fabric qualities
-u :
Credit loop check based on UpDown rules
-t <topo-file> :
Specifies the topology file name. The system name
(-s) must also be specified if this option is used.
-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
-skip <skip-option(s)> :
Skip the executions of the selected checks. Skip

options (one or more can be specified) : dup_guids
zero_guids pm logical_state part ipoib all
-wt <file-name>> :
Write out the discovered topology into the given
file. This flag is useful if you later want to check
for changes from the current state of the fabric. A
directory named ibdiag_ibnl is also created by this
option, and holds the IBNL files required to load
this topology. To use these files you will need to
set the environment variable named IBDM_IBNL_PATH to
that directory. The directory is located in /tmp or
in the output directory provided by the -o flag.
-load_db <file-name>> :
Load subnet data from the given .db file, and skip
subnet discovery stage. Note: Some of the checks
require actual subnet discovery, and therefore would
not run when load_db is specified. These checks are
: Duplicated/zero guids, link state, SMs status.
-vlr :
VL based Routing - provide this option to create the
paths SL file (psl), SL2VL file (slvl) and use them
in credit loops check (if -r option is provided).
NOTE: Since number of paths is N^2 extracting the
PSL file may take some time.
-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
ERROR CODES

2 - Failed to parse command line options
3 - Failed to intract with IB fabric
4 - Failed to use local device or local port
5 - Failed to use Topology File
6 - Failed to load requierd Package
