DESCRIPTION

17       ibdiagnet scans the fabric using directed route packets and extracts
18       all the available information regarding its connectivity and devices.
19       It then produces the following files in the output directory (which
20       defined by the -o option (see below)).
21

FILES

23       ibdiagnet.log -
24           A dump of all the application reports generate according to the
25           provided flags
26
27       ibdiagnet.lst -
28           List of all the nodes, ports and links in the fabric
29
30       ibdiagnet.fdbs -
31           A dump of the unicast forwarding tables of the fabric switches
32
33       ibdiagnet.mcfdbs -
34           A dump of the multicast forwarding tables of the fabric switches
35
36       ibdiagnet.masks -
37           In case of duplicate port/node Guids, these file include the map
38           between masked Guid and real Guids
39
40       ibdiagnet.sm -
41           List of all the SM (state and priority) in the fabric
42
43       ibdiagnet.pm -
44           A dump of the pm Counters values, of the fabric links
45
46       ibdiagnet.pkey -
47           A dump of the the existing partitions and their member host ports
48
49       ibdiagnet.mcgs -
50           A dump of the multicast groups, their properties and member host
51           ports
52
53       ibdiagnet.psl -
54           A dump of the path record SL of each possible source node guid and
55           DLID pairs.  Created only if -vlr option is provided
56
57       ibdiagnet.slvl -
58           A dump of the SL2VL Tables from all the switches.  Created only if
59           -vlr option is provided
60
61       ibdiagnet.db -
62           A dump of the internal subnet database. This file can be loaded in
63           later runs using the -load_db option
64
65       In addition to generating the files above, the discovery phase also
66       checks for duplicate node/port GUIDs in the IB fabric. If such an error
67       is detected, it is displayed on the standard output. After the
68       discovery phase is completed, directed route packets are sent multiple
69       times (according to the -c option) to detect possible problematic paths
70       on which packets may be lost. Such paths are explored, and a report of
71       the suspected bad links is displayed on the standard output.
72
73       After scanning the fabric, if the -r option is provided, a full report
74       of the fabric qualities is displayed.  This report includes:
75
76SM report
77
78Number of nodes and systems
79
80Hop-count information
81
82            maximal hop-count, an example path, and a hop-count histogram
83All CA-to-CA paths traced
84
85Credit loop report
86
87mgid-mlid-HCAs multicast group and report
88
89Partitions report
90
91IPoIB report
92
93       Note: In case the IB fabric includes only one CA, then CA-to-CA paths
94       are not reported.  Furthermore, if a topology file is provided,
95       ibdiagnet uses the names defined in it for the output reports.
96

OPTIONS

98       -c <count>      :
99            Min number of packets to be sent across each link (default = 10)
100       -v              :
101            Enable verbose mode
102       -r              :
103            Provides a report of the fabric qualities
104       -u              :
105            Credit loop check based on UpDown rules
106       -t <topo-file>  :
107            Specifies the topology file name
108       -s <sys-name>   :
109            Specifies the local system name. Meaningful only if a topology
110           file is specified
111       -i <dev-index>  :
112            Specifies the index of the device of the port used to connect to
113           the IB fabric (in case of multiple devices on the local system)
114       -p <port-num>   :
115            Specifies the local device's port num used to connect to the IB
116           fabric
117       -o <out-dir>    :
118            Specifies the directory where the output files will be placed
119           (default = /tmp)
120       -lw <1x|4x|12x> :
121            Specifies the expected link width
122       -ls <2.5|5|10>  :
123            Specifies the expected link speed
124       -pm             :
125            Dump all the fabric links, pm Counters into ibdiagnet.pm
126       -pc             :
127            Reset all the fabric links pmCounters
128       -P <PM=<Trash>> :
129            If any of the provided pm is greater then its provided value,
130           print it to screen
131       -skip <skip-option(s)> :
132            Skip the executions of the selected checks. Skip options (one or
133           more can be specified) : dup_guids  zero_guids pm logical_state
134           part ipoib all
135       -wt <file-name>> :
136            Write out the discovered topology into the given file. This flag
137           is useful if you later want to check for changes from the current
138           state of the fabric. A directory named ibdiag_ibnl is also created
139           by this option, and holds the IBNL files required to load this
140           topology. To use these files you will need to set the environment
141           variable named IBDM_IBNL_PATH to that directory. The directory is
142           located in /tmp or in the output directory provided by the -o flag.
143       -load_db <file-name>> :
144            Load subnet data from the given .db file, and skip subnet
145           discovery stage. Note: Some of the checks require actual subnet
146           discovery, and therefore would not run when load_db is specified.
147           These checks are : Duplicated/zero guids, link state, SMs status.
148       -vlr :
149            VL based Routing - provide this option to create the paths SL file
150           (psl), SL2VL file (slvl) and use them in credit loops check (if -r
151           option is provided).
152               NOTE: Since number of paths is N^2 extracting the PSL file may
153               take some time.
154
155       -h|--help       :
156            Prints the help page information
157       -V|--version    :
158            Prints the version of the tool
159       --vars          :
160            Prints the tool's environment variables and their values
