[ofa-general] dapltest couldn't read ABI version

[Wen Hao Wang]

Hi all:

I installed OFED 1.3.1 and 1.4 RC1 on my SLES10 SP2 x86_64 servers.
dapltest failed to be run as server model. Following error is reported:

LS21-05:~ # dapltest -T S -d -D ib0
Server_Cmd.debug:       1
Server_Cmd.dapl_name: ib0
librdmacm: couldn't read ABI version.
librdmacm: assuming: 4
CMA: unable to open /dev/infiniband/rdma_cm
LS21-05:32561:  open_hca: ERR - RDMA channel No such file or directory
LS21-05:32561: dapls_ib_open_hca failed 40000
DT_cs_Server: Could not open ib0 (DAT_INTERNAL_ERROR )
DT_cs_Server: Waiting for clients to all go away...
DT_cs_Server: Cleaning up ...
DT_cs_Server (ib0):  Exiting.

File /dev/infiniband/rdma_cm exists on RHEL servers, but not on SLES
servers. ib0 can communicate with other servres. Any advice or comments?
Thanks in advance!
