-g|--guid <GUID in hex> Specifies the local port GUID value of the port used to con-
nect to the IB fabric. If GUID given is 0 than ibdiagnet dis-
plays a list of possible port GUIDs and waits for user input.
--vlr <file> Specifies opensm-path-records.dump file path, src-dst to SL
mapping generated by SM plugin. ibdiagnet will use this map-
ping for MADs sending and credit loop check (if -r option
selected).
-r|--routing Provides a report of the fabric qualities.
-u|--fat_tree Indicates that UpDown credit loop checking should be done
against automatically determined roots.
-o|--output_path <directory> Specifies the directory where the output files will be
placed.(default="/var/tmp/ibdiagnet2/").
--skip <stage> Skip the executions of the given stage. Applicable skip
stages:(all | dup_guids | dup_node_desc | lids | links | sm |
pm | nodes_info | speed_width_check | pkey | aguid).
--skip_plugin <library name> Skip the load of the given library name. Applicable skip
plugins:(libibdiagnet_cable_diag_plugin |
libibdiagnet_cable_diag_plugin-2.1.1).
--pc Reset all the fabric PM counters.
-P|--counter <<PM>=<value>> If any of the provided PM is greater then its provided value
than print it.
--pm_pause_time <seconds> Specifies the seconds to wait between first counters sample
and second counters sample. If seconds given is 0 than no
second counters sample will be done. (default=1).
--ber_test Provides a BER test for each port. Calculate BER for each
port and check no BER value has exceeds the BER threshold.
(default threshold="10^-12").
--ber_use_data Indicates that BER test will use the received data for calcu-
lation.
--ber_thresh <value> Specifies the threshold value for the BER test. The recipro-
cal number of the BER should be provided. Example: for 10^-12
than value need to be 1000000000000 or 0xe8d4a51000
(10^12).If threshold given is 0 than all BER values for all
ports will be reported.
--extended_speeds <dev-type> Collect and test port extended speeds counters. dev-type: (sw
| all).
--pm_per_lane List all counters per lane (when available).
--ls <2.5|5|10|14|25|FDR10> Specifies the expected link speed.
--lw <1x|4x|8x|12x> Specifies the expected link width.
-w|--write_topo_file <file
name>
Write out a topology file for the discovered topology.
-t|--topo_file <file> Specifies the topology file name.
--out_ibnl_dir <directory> The topology file custom system definitions(ibnl) directory.
--screen_num_errs <num> Specifies the threshold for printing errors to screen.
(default=5).
--smp_window <num> Max smp MADs on wire. (default=8).
--gmp_window <num> Max gmp MADs on wire. (default=128).
--max_hops <max-hops> Specifies the maximum hops for the discovery pro-
cess.(default=64).
