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)).
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.mcg −
A dump of the multicast groups, their properties and member host ports
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:
* 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 multicast group and report
* Partitions report
* 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.
−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
−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.
−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
