IBDIAGNET(1) IB DIAGNOSTIC PACKAGE IBDIAGNET(1)NAME
ibdiagnet - IB diagnostic net
SYNOPSYS
ibdiagnet [-c <count>] [-v] [-r] [-t <topo-file>] [-s <sys-name>]
[-i <dev-index>] [-p <port-num>] [-o <out-dir>] [-lw <1x⎪4x⎪12x>]
[-ls <2.5⎪5⎪10>] [-pm] [-pc] [-P <<PM counter>=<Trash Limit>>]
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
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 discov‐
ery 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, ibdiag‐
net uses the names defined in it for the output reports.
OPTIONS-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
