[Pvfs2-users] no connection on infiniband dual port card

[vlad]

Hi!

I`m  evaluating now version 2.8.5  and I have been able to connect  and
use hosts with single port infiniband cards (Mellanox Infinihost III, )
using  the ib0 Interface, connection set to 

 ib://host:3335/pvfs2

Integrating of hosts with 2-port cards fails. On this hosts I have 
plugged in port ib1, configured IPoverIB and I'm able to ping between the
infiniband hosts. I have also an OpenSM Subnet Manager running on each
host.

When starting the servers on these hosts they complain about that they
cannot reach the other pvfs2-servers and I should check if my subnetmanager
on that particular host is running.

I suppose, the connection request is sent on ib0 instead of ib1.

My question is, if there are any parameters to tell the server to use port
1 instead of port 0   

Despite of all, everything runs very fine  and we have very nice data
transfers (the 1-port 5 Nodes are writing with 415 MB per second).


I would appreciate any help.
