Hal,
The procedure is a little different. You'll need to create a child
interface (on a partition) first and then you will be able to
configure it as follows:
echo 0x8001> /sys/class/net/ib0/create_child
ifconfig ib0.8001 ...
Note that you'll want the 0x8000 bit on for full membership.
What does "full membership" mean? And are you saying that for full
membership, any value beginning with 0x8 would work? Can an HCA have
full membership on multiple partitions simultaneously?
Thanks,
Tom

Hi,
I have some basic questions about IB partitions.
Can an HCA port belong to more than 1 partition at a time?
Yes.
How do you configure partitions with opensm? From reading the opensmd
man page, it looks like you just create a file called
/etc/osm-partitions.conf, with port GUIDs and such, but is this current?
The default location depends on how OpenSM is configured/built.
I missed this the first time around:
and yes, the syntax indicated is current.

I ask because according to the man page the opensm configuration file is
in /etc/opensm/ . Can you tell opensm where to look for the partitions
file?
Yes, with either the -P option on the command line or
partition_config_file line in the options file.
