NAME
ibdiscover.pl - annotate and compare InfiniBand topology
SYNOPSIS
ibdiscover.pl
DESCRIPTION
ibdiscover.pl uses a topology file create by ibnetdiscover and a dis‐
cover.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 adminis‐
trator 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 ibdis‐
cover.topo.new) are:
<LocalPort>|<LocalNodeGUID>|<RemotePort>|<RemoteNodeGUID>
e.g.
10|5442ba00003080|1|8f10400410015
These topo files are produced by the ibdiscover.pl tool.
