We seem to be working with a given configuration just fine on RHEL 5.2
w/ OFED 1.3 and it's bundled Open iSCSI. We are failing to login
with the same configuration parameters running OFED v1.4 RC6. Is
anyone having issues with iSER on this newer build on RHEL 5.2? Did
the configuration options change?
Thanks

For me, this ended up being that the CM service was not yet
configured at the time that I was attempting to login. So, it is
possible that you need to set the port settling time attribute to
ensure that the port are configured properly. Sameer, ping me
directly if you need further assistance.

Am I missing something here? is iSER transport available in v1.4?
You are getting REJECTED (8) event with the reject reason being
INVALID_SERVICE_ID (8), see include/rdma/ib_cm.h. This means
there's no one listening on the Service-ID you are attempting to
connect to, eg your target didn't issue a listen call on the SID
(service id) you are trying to connect to or there's some mismatch
is the SID as constructed by the initiator, etc.
Related inter-op issue has been brought by Jesse Butler from Sun
couple of months ago, http://lists.openfabrics.org/pipermail/general/2008-October/054487.html
but I am not sure where it stands.
The code that builds the SID from the tcp port is
cma_get_service_id (drivers/infiniband/core/cma.c, below) where in
this case the resulted SID is 0x0000000001060cbc
Or.
static __be64 cma_get_service_id(enum rdma_port_space ps, struct
sockaddr *addr)
{
return cpu_to_be64(((u64)ps << 16) + be16_to_cpu(cma_port(addr)));
}
