Is the driver loaded ? ie., do an /sbin/lsmod to see.
Ah ha -- no, it is not:
[11:51] svbu-mpi005:/etc/udev/rules.d % /sbin/lsmod | grep rdma
[11:51] svbu-mpi005:/etc/udev/rules.d %
What would cause it to not be loaded? I *assumed* (but didn't check)
that it is loaded as part of OFED's /etc/init.d/openibd. Is that
correct?
Also are there any messages that would indicate a
problem when you do a dmesg.
As I indicated in my first mail :-), no.

Subject: [ewg] /dev/infiniband/rdma_cm not created
I'm running on rhel4u6 with the 1.4.1 nightly from last night and
sometimes /dev/infiniband/rdma_cm is not created. I can see its entry
in /etc/udev/rules.d/90-ib.rules:
KERNEL="umad*", NAME="infiniband/%k"
KERNEL="issm*", NAME="infiniband/%k"
KERNEL="ucm*", NAME="infiniband/%k", MODE="0666"
KERNEL="uverbs*", NAME="infiniband/%k", MODE="0666"
KERNEL="ucma", NAME="infiniband/%k", MODE="0666"
KERNEL="rdma_cm", NAME="infiniband/%k", MODE="0666"
But only some of these are created:
[11:29] svbu-mpi005:/etc/udev/rules.d % l /dev/infiniband/
total 0

I have both an IB HCA and an iWARP RNIC in this server:

I don't see any obvious errors occurring in syslog or dmesg.
What could cause this failure?
