[openib-general] [ANNOUNCE] Updated OpenIB diagnostics

[Hal Rosenstock]

Hi,

The OpenIB diagnostics
(https://openib.org/svn/gen2/trunk/src/userspace/management/diags) have
been updated as follows:

1. discover.pl diagnostic tool added
discover.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 discover.topo file which is the expected connectivity
and produces a new connectivity file (discover.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 discover.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 (discover.topo and discover.topo.new)
are:
<LocalPort>|<LocalNodeGUID>|<RemotePort>|<RemoteNodeGUID>
e.g.
10|5442ba00003080|1|8f10400410015

These topo files are produced by the discover.pl tool.

2. ibportstate diagnostic tool added to query, disable, and enable
switch ports

3. Added error only mode to diagnostic scripts so less data to weed
through on a large fabric (also verbose mode to see everything)

4. Tree structure collapsed so all tools in same directory as opposed to
individual ones and build simplified

Let me know about any comments or issues. Thanks.

-- Hal
