Diagnostic Tools
Model of operation: All utilities use direct MAD access to operate. Operations that require QP 0 mads only, may use direct routed mads, and therefore may work even in subnets that are not configured. Almost all utilities can operate without accessing the SM, unless GUID to lid translation is required.
Dependencies
Multiple port/Multiple CA support:
When no InfiniBand device or port is specified (as shown in the following example for "Local umad parameters"), the tools select the interface port to use by the following criteria:
- The first InfiniBand ACTIVE port.
- If not found, the first InfiniBand port that is UP (physical link up).
If a port and/or CA name is specified, the tool attempts to fulfill the user’s request and will fail if it is not possible.
For example:
ibaddr # use the 'best port' 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.
Common Options & Flags
Most diagnostics take the following flags. The exact list of supported flags per utility can be found in the usage message and can be shown using util_name -h syntax.
# Debugging flags
-d raise the IB debugging level. May be used several times (-ddd or -d -d -d).
-e show umad send receive errors (timeouts and others)
-h show the usage message
-v increase the application verbosity level.
May be used several times (-vv or -v -v -v)
-V show the internal version info.
# Addressing flags
-D use directed path address arguments.
The path is a comma separated list of out ports.
Examples:
"0" # self port
"0,1,2,1,4" # out via port 1, then 2, ...
-G use GUID address arguments.
In most cases, it is the Port GUID.
Examples:
"0x08f1040023"
-s <smlid> use 'smlid' as the target lid for SA queries.
# Local umad parameters:
-C <ca_name> use the specified ca_name.
-P <ca_port> use the specified ca_port.
-t <timeout_ms> override the default timeout for the
solicited mads.
CLI notation: all utilities use the POSIX style notation, meaning that all options (flags) must precede all arguments (parameters).

ibnetsplit
Automatically groups hosts and creates scripts that can be run in order to split the network into sub-networks containing one group of hosts.
Syntax
Group:
ibnetsplit [-v][-h][-g grp-file] -s <.lst|.net|.topo> <-r head-ports|-d max-dist>
Split:
ibnetsplit [-v][-h][-g grp-file] -s <.lst|.net|.topo> -o out-dir
Combined:
ibnetsplit [-v][-h][-g grp-file] -s <.lst|.net|.topo> <-r head-ports|-d max-dist> -o out-dir
Usage
- Grouping:
The grouping is performed if the -r or -d options are provided.
- If the -r is provided with a file containing group head ports, the algorithm examines the hosts distance from the set of node ports provided in the head-ports file (these are expected to be the ports running standby SM's).
If the -d is provided with a maximum distance of the hosts in each group, the algorithm partition the hosts by that distance.
This method of analyzation may not be suitable for some topologies.
The results of the identified groups are printed into the file defined by the -g option (default ibnetsplit.groups) and can be manually edited. For groups where the head port is a switch, the group file uses the FIRST host port as the port to run the isolation script from.
- Splitting:
- If the -o flag is included, this algorithm analyzes the MinHop table of the topology and identifies the set of links and switches that may potentially be used for routing each group ports. The cross-switch links between switches of the group to other switches are declared as split-links and the commands to turn them off using Directed Routes from the original Group Head ports are written into the out-dir provided by the -o flag.
Both stages require a subnet definition file to be provided by the -s flag. The supported formats for subnet definition are:
- *.net - for ibnetdiscover
- *.lst - for opensm-subnet.lst or ibiagnet.lst
- *.topo - for a topology file
HEAD PORTS FILE
This file is provided by the user and defines the ports by which grouping of the other host ports is defined.
Format:
Each line should contain either the name or the GUID of a single port. For switches the port number shall be 0.
<node-name>/P<port-num>|<PGUID>
GROUPS FILE
This file is generated by the program if the head-ports file is provided to it. Alternatively it can be provided (or edited) by the user if different grouping is desired. The generated script for isolating or connecting the group should be run from the first node in each group.
Format:
Each line may be either:
GROUP: <group name> <node-name>/P<port-num>|<PGUID>
