I'm trying to set up partitions in a little test environment, and I'm

I have opensm running on a machine attached to the fabric, and sminfo on

/etc/opensm/partitions.conf:
Default=0xffff , ipoib : ALL, SELF=full ;
PartitionBlue=0x8004, ipoib : 0x0002c9030009cb3f=full,
0x0002c90200252841=full, 0x0002c90200243471=full ;
PartitionRed=0x8005, ipoib : 0x0002c90200252841=full,
0x0002c90200243591=full, 0x0002c9030009cb2b=full ;
You don't really need the 0x8000 bit on in the pkeys but I don't think
it does any harm.
But when I go to the machine with port GUID 0x0002c90200243471, it
doesn't appear that it's getting the pkey I wanted:

What does:
smpquery pkeys 10 1
say ? Do you see the other pkey(s) on that port ?
[r...@stagnate ~]# smpquery pkeys 10 1

64 pkeys capacity for this port
So I see that both 7fff and 8004 are being assigned to this port. Is
that okay? Is there any problem with the machine also being in the
default partition?
As I look around at all of the machines with smpquery, it appears that
they are all being assigned 7fff and the pkey that I assigned in
partitions.conf.
But the machine that I want to run 2 child interfaces on is having
issues. It's at LID 7 and here's what smpquery says:
[r...@stagnate ~]# smpquery pkeys 7 1
0: 0x7fff 0x8004 0x8005 0x0000 0x0000 0x0000 0x0000 0x0000
8: 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000
16: 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000
24: 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000 0x0000

64 pkeys capacity for this port
So that's fine, but when I try to create a child interface I get this:
[r...@labdisk01 ~]# echo 0x8004 > /sys/class/net/ib0/create_child
-bash: echo: write error: Name not unique on network
My plan was to create two child interfaces (0x8004 and 0x8005) and then
ifconfig ib0.8004 and ifconfig ib0.8005 to assign them to separate subnets.
Tom
The pkey you are seeing is the only one for ib0 interface.
If you want to have IPoIB interfaces on the other partitions too, you
need to set this up by creating a child interface on those nodes; you
had asked about that in a previous email
(http://www.mail-archive.com/linux-rdma@vger.kernel.org/msg04728.html).

I'm trying to run one ipoib subnet in each partition, and then
eventually the goal is to have a different server that has 2 child
interfaces, one on each subnet. But it doesn't appear that my partition
configuration is even correct. Is there a syntax error, or something
else I am missing?
Thanks,
Tom
