IBQUERYERRORS(8) OpenIB Diagnostics IBQUERYERRORS(8)NAME
IBQUERYERRORS - query and report IB port counters
SYNOPSISibqueryerrors [options]
DESCRIPTION
The default behavior is to report the port error counters which exceed
a threshold for each port in the fabric. The default threshold is zero
(0). Error fields can also be suppressed entirely.
In addition to reporting errors on every port. ibqueryerrors can
report the port transmit and receive data as well as report full link
information to the remote port if available.
OPTIONS-s, --suppress <err1,err2,...> Suppress the errors listed in the comma
separated list provided.
-c, --suppress-common Suppress some of the common "side effect" coun‐
ters. These counters usually do not indicate an error condition and
can be usually be safely ignored.
-r, --report-port Report the port information. This includes LID,
port, external port (if applicable), link speed setting, remote GUID,
remote port, remote external port (if applicable), and remote node
description information.
--data Include the optional transmit and receive data counters.
--threshold-file <filename> Specify an alternate threshold file. The
default is /etc/infiniband-diags/error_thresholds
--switch print data for switch's only
--ca print data for CA's only
--router print data for routers only
--clear-errors -k Clear error counters after read.
--clear-counts -K Clear data counters after read.
CAUTION clearing data or error counters will occur regardless of if
they are printed or not. See --counters and --data for details on con‐
troling which counters are printed.
--details include receive error and transmit discard details
--counters print data counters only
Partial Scan flags
The node to start a partial scan can be specified with the following
addresses.
--port-guid, -G <port_guid> Specify a port_guid
-D, --Direct <dr_path> The address specified is a directed route
Examples:
-D "0" # self port
-D "0,1,2,1,4" # out via port 1, then 2, ...
(Note the second number in the path specified must match the port being
used. This can be specified using the port selection flag '-P' or the
port found through the automatic selection process.)
Note: For switches results are printed for all ports not just switch
port 0.
-S <port_guid> same as "-G". (provided only for backward compatibility)
Cache File flags
--load-cache <filename> Load and use the cached ibnetdiscover data
stored in the specified filename. May be useful for outputting and
learning about other fabrics or a previous state of a fabric.
Port Selection flags
-C, --Ca <ca_name> use the specified ca_name.
-P, --Port <ca_port> use the specified ca_port.
Local port Selection
Multiple port/Multiple CA support: when no IB device or port is speci‐
fied (see the "local umad parameters" below), the libibumad library
selects the port to use by the following criteria:
1. the first port that is ACTIVE.
2. if not found, the first port that is UP (physical link up).
If a port and/or CA name is specified, the libibumad library
attempts to fulfill the user request, and will fail if it is not
possible.
For example:
ibaddr # use the first port (criteria #1 above)
ibaddr -C mthca1 # pick the best port from "mthca1" only.
ibaddr -P 2 # use the second (active/up) port from the first available IB device.
ibaddr -C mthca0 -P 2 # use the specified port only.
Configuration flags
--config, -z <config_file> Specify alternate config file.
Default: /etc/infiniband-diags/ibdiag.conf
--outstanding_smps, -o <val>
Specify the number of outstanding SMP's which should be issued
during the scan
Default: 2
--node-name-map <node-name-map> Specify a node name map.
This file maps GUIDs to more user friendly names. See FILES sec‐
tion.
-t, --timeout <timeout_ms> override the default timeout for the
solicited mads.
-y, --m_key <key>
use the specified M_key for requests. If non-numeric value (like
'x') is specified then a value will be prompted for.
Debugging flags
-d raise the IB debugging level. May be used several times (-ddd
or -d -d -d).
-e show send and receive errors (timeouts and others)
-h, --help show the usage message
-v, --verbose
increase the application verbosity level. May be used several
times (-vv or -v -v -v)
-V, --version show the version info.
-R (This option is obsolete and does nothing)
EXIT STATUS-1 if scan fails.
0 if scan succeeds without errors beyond thresholds
1 if errors are found beyond thresholds or inconsistencies are found in
check mode.
FILES
ERROR THRESHOLD
/etc/infiniband-diags/error_thresholds
Define threshold values for errors. File format is simple "name=val".
Comments begin with '#'
Example:
# Define thresholds for error counters
SymbolErrorCounter=10
LinkErrorRecoveryCounter=10
VL15Dropped=100
CONFIG FILE
/etc/infiniband-diags/ibdiag.conf
A global config file is provided to set some of the common options for
all tools. See supplied config file for details.
NODE NAME MAP FILE FORMAT
The node name map is used to specify user friendly names for nodes in
the output. GUIDs are used to perform the lookup.
This functionality is provided by the opensm-libs package. See
opensm(8) for the file location for your installation.
Generically:
# comment
<guid> "<name>"
Example:
# IB1
# Line cards
0x0008f104003f125c "IB1 (Rack 11 slot 1 ) ISR9288/ISR9096 Voltaire sLB-24D"
0x0008f104003f125d "IB1 (Rack 11 slot 1 ) ISR9288/ISR9096 Voltaire sLB-24D"
