I've changed the string as you've advised, but it didn't work. The only
difference is that string "" was added in /var/log/messages.
root@[...] echo -n
id_ext=0000000000000001,ioc_guid=00066a01380001de,dgid=fe8000000000000000066a02600001de,pkey=ffff,service_id=0000494353535250,io_class=ff00
> /sys/class/infiniband_srp/srp-mthca0-1/add_target
root@[...] tail /var/log/messages
Oct 18 14:01:26 ... kernel: REJ reason 0x0
Oct 18 14:01:26 ... kernel: ib_srp: Connection failed
By the way, in ofed srp_release_notes.txt hasn't been said that io_class is
mandatory parameter.

The problem is with the echo string you are giving. The command should
be invoked as:
echo -n id_ext=0000000000000001,ioc_guid=00066a01380001de,dgid=fe80000
00000000000066a02600001de,pkey=ffff,service_id=0000494353535250,
io_class=ff00 > /sys/class/infiniband_srp/srp-mthca0-1/add_target
You were missing the 'io_class=ff00' bit.
Let me know if it works.
