Okay, how about this.
With ethernet and a linux server, I can set up up aliases (virtual IP
addresses) and assign multiple IPs to a single NIC. Can this be done
with an HCA and IPoIB? For example, could I configure ib0:1 to be
192.168.0.1/24 and ib0:2 to be 10.0.0.1/24?
I have tried this on a RHEL5 box and it doesn't seem to want to accept
it, but I don't know if there is another piece somewhere that I need to
configure.

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.

Thanks,
