IBDISCOVER.PL(8) OpenIB Diagnostics IBDISCOVER.PL(8)NAME
ibdiscover.pl - annotate and compare InfiniBand topology
SYNOPSIS
ibdiscover.pl
DESCRIPTION
ibdiscover.pl uses a topology file create by ibnetdiscover and a discover.map file which the network administrator creates which indicates
the nodes to be expected and a ibdiscover.topo file which is the expected connectivity and produces a new connectivity file (dis-
cover.topo.new) and outputs the changes to stdout. The network administrator can choose to replace the "old" topo file with the new one or
certain changes in.
The syntax of the ibdiscover.map file is:
<nodeGUID>|port|"Text for node"|<NodeDescription from ibnetdiscover format>
e.g.
8f10400410015|8|"ISR 6000"|# SW-6IB4 Voltaire port 0 lid 5
8f10403960558|2|"HCA 1"|# MT23108 InfiniHost Mellanox Technologies
The syntax of the old and new topo files (ibdiscover.topo and ibdiscover.topo.new) are:
<LocalPort>|<LocalNodeGUID>|<RemotePort>|<RemoteNodeGUID>
e.g.
10|5442ba00003080|1|8f10400410015
These topo files are produced by the ibdiscover.pl tool.

IBNODES - show InfiniBand nodes in topology
SYNOPSIS
ibnodes [options] [<topology-file>]
DESCRIPTION
ibnodes is a script which either walks the IB subnet topology or uses an already saved topology file and extracts the IB nodes (CAs and
switches).
OPTIONS -C, --Ca <ca_name> use the specified ca_name.
-P, --Port <ca_port> use the specified ca_port.
-t, --timeout <timeout_ms> override the default timeout for the solicited mads.
-h, --help show the usage message
--config, -z <config_file> Specify alternate config file.
Default: /etc/infiniband-diags/ibdiag.conf
Local port Selection
Multiple port/Multiple CA support: when no IB device or port is specified (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.
FILES
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:
