[ofa-general] opensm error when running ibsim

[Vincent Ficet]

Hello,

When running the latest opensm with ibsim, I get the following error:

[user at host:~ ] ibsim -s ibsim/net-examples/net.1
[ ... ]

[user at host:~ ] export LD_PRELOAD=/path/to/libumad2sim.so
[user at host:~ ] opensm -f -
...
OpenSM 3.2.2

ibwarn: [32336] sim_connect: attached as client 2 at node "Switch1"
Entering DISCOVERING state


Error from osm_opensm_bind (0x2A)
Perhaps another instance of OpenSM is already running
Exiting SM

However, no other instance of opensm was running at that time. Digging 
further, I realised that commenting out the 'guid' entry in opensm.conf 
fixed this issue.

==> Shouldn't opensm have some mechanism that excludes this parameter 
when a connection to the sim:ctl socket is made ?

Cheers,

Vincent
